You should undefine CONFIG_SKIP_LOWLEVEL_INIT + in "include/configs/adp-ag101.h". + +Build and boot steps +==================== + +build: +1. Prepare the toolchains and make sure the $PATH to toolchains is correct. +2. Use `make adp-ag101` in u-boot root to build the image. + +burn u-boot to flash: +1. Make sure the MA17 (J16) is Lo. +2. Make sure the dip switch SW5 is set to "0101". +3. Power On. Press button "S1", then press button "SW1", then you will found the + debug LED show 67 means the system successfully booted into e-bios. + Now you can control the e-bios boot loader from your console. +4. Under "Command>>" prompt, enter "97" (CopyImageFromCard) +5. Under "Type Dir Name of [CF/SD] =>" promtp, enter "c". +6. Under "Enter Filename =>" prompt, enter the file name of u-boot image you + just build. It is usually "u-boot.bin". +7. Under "Enter Dest. Address =>" prompt, enter the memory address where you + want to put the binary from SD card to RAM. + Address "0x500000" is our suggestion. +8. Under "Command>>" prompt again, enter "55" (CLI) to use interactive command + environment. +9. Under "CLI>" prompt, enter "burn 0x500000 0x80400000 0x30000" to burn the + binary from RAM to FLASH. +10. Under "CLI>" prompt, enter "exit" to finish the burn process. + +boot u-boot from flash: +1.

By default, the ebony code uses +the SPD to initialize the DDR SDRAM control registers. So if the SPD +eeprom is corrupted, U-Boot will never get into ram. Here's how I got +out of this situation: + +0. First, _before_ playing with the i2c utilities, do an 'i2c probe', then +use 'i2c md' to capture the various device contents to a file. Some day +you may be glad you did this ... trust me :-). Otherwise try the +following: + +1. In the include/configs/EBONY.h file find the line that defines +the CONFIG_SPD_EEPROM macro and undefine it. E.g: + +#undef CONFIG_SPD_EEPROM + +This will make the code use default SDRAM control register +settings without using the SPD eeprom. + +2. Rebuild U-Boot + +3. Load the new U-Boot image and reboot ebony. + +4. Repair the SPD eeprom using the 'i2c mm' command. Here's the eeprom +contents that work with the default SO-DIMM that comes with the +ebony board (micron 8VDDT164AG-265A1).

The hawkboard comes with a 128MiB Nand flash and a 128MiB +DDR SDRAM along with a host of other controllers. + +The hawkboard is booted in three stages. The initial bootloader which +executes upon reset is the Rom Boot Loader(RBL) which sits in the +internal ROM of the omap. The RBL initialises the memory and the nand +controller, and copies the image stored at a predefined location(block +1) of the nand flash. The image loaded by the RBL to the memory is the +AIS signed spl image. This, in turns copies the u-boot binary from the +nand flash to the memory and jumps to the u-boot entry point. + +AIS is an image format defined by TI for the images that are to be +loaded to memory by the RBL. The image is divided into a series of +sections and the image's entry point is specified. Each section comes +with meta data like the target address the section is to be copied to +and the size of the section, which is used by the RBL to load the +image. At the end of the image the RBL jumps to the image entry +point. + +The secondary stage bootloader(spl) which is loaded by the RBL then +loads the u-boot from a predefined location in the nand to the memory +and jumps to the u-boot entry point. + +The reason a secondary stage bootloader is used is because the ECC +layout expected by the RBL is not the same as that used by +u-boot/linux. This also implies that for flashing the spl image,we +need to use the u-boot which uses the ECC layout expected by the +RBL[1].

FLASH0 contains 16 MiB, and is mapped to +addresses 0xFF000000 - 0xFFFFFFFF as U-Boot Flash Bank #2. FLASH1 contains +from 16 to 128 MiB, and is mapped to 0xF?000000 - 0xF7FFFFFF as U-Boot Flash +Bank #1 (with the starting address depending on the flash size detected at +runtime). The write-enable pin on FLASH0 is disabled, so the contents of FLASH0 +cannot be modified in the field. This also prevents FLASH0 from executing +commands to return chip information, so its configuration is hard-coded in +U-Boot. + +There are two versions of U-Boot for Korat: "permanent" and "upgradable". The +permanent U-Boot is pre-programmed at the top of FLASH0, e.g., at addresses +0xFFFA0000 - 0xFFFFFFFF for the current 384 KiB size. The upgradable U-Boot is +located 256 KiB from the top of FLASH1, e.g. at addresses 0xF7F6000 - 0xF7FC0000 +for the current 384 KiB size. FLASH1 addresses 0xF7FE0000 - 0xF7FF0000 are +used for the U-Boot environmental parameters, and addresses 0xF7FC0000 - +0xF7FDFFFF are used for the redundant copy of the parameters. These locations +are used by both versions of U-Boot. + +On booting, the permanent U-Boot in FLASH0 begins executing. After performing +minimal setup, it monitors the state of the board's Reset switch (GPIO47). If +the switch is sensed as open before a timeout period, then U-Boot branches to +address 0xF7FBFFFC. This causes the upgradable U-Boot to execute from the +beginning. If the switch remains closed thoughout the timeout period, the +permanent U-Boot activates the on-board buzzer until the switch is sensed as +opened. It then continues to execute without branching to FLASH1. The effect +of this is that normally the Korat board boots its upgradable U-Boot, but, if +this has been corrupted, the user can boot the permanent U-Boot, which can then +be used to erase and reload FLASH1 as needed. + +Note that it is not necessary for the permanent U-Boot to have all the latest +features, but only that it have sufficient functionality (working "tftp", +"erase", "cp.b", etc.) to repair FLASH1. Also, the permanent U-Boot makes no +assumptions about the size of FLASH1 or the size of the upgradable U-Boot: it is +sufficient that the upgradable U-Boot can be started by a branch to 0xF7FBFFFC. + +The build sequence: + + make korat_perm_config + make all + +builds the permanent U-Boot by selecting loader file "u-boot.lds" and defining +preprocessor symbol "CONFIG_KORAT_PERMANENT". The default build: + + make korat_config + make all + +creates the upgradable U-Boot by selecting loader file "u-boot-F7FC.lds" and +leaving preprocessor symbol "CONFIG_KORAT_PERMANENT" undefined. + +2008-02-22, Larry Johnson <lrj@acm.org> + + +The CompactFlash(R) controller on the Korat board provides a hi-speed USB +interface.

If the variable defined and set to "ppc", then the +PowerPC USB port is used.

You can't clear it out +because it is battery backed and once it is set wrong, it stays +wrong. The only way to reset it, so that it takes on it's default +multiplier is to disconnect all power including external, batteries, +as well discharging caps on the board. This precludes the fact that +your 860 may be quite DEAD by this time! + +If you don't setup the multiplication factor for boards that use the +OSCM input, they won't run correctly, but at least they won't be +dead. + +Addtionally, there is no good way to determine the clock input source +from CPU register data. The only way to deal with this is either hard +code it, determine the correct value with some rather NASTY timing +loops, or try to grok it from external data sources. Motorola +firmware opts for the NASTY timing loops, but needs to configure the +serial ports to do so. + + +You may have a legitimate need to define CONFIG_SYS_USE_OSCCLK if your +MBX8xx board is

The bootfile image must contain +the U-Boot image header. Since CDs do not have "partitions", the boot partition is 0. +The bootcatalog feature has not been tested so far.

Corrected this behavior, but only if +CONFIG_SYS_CONSOLE_IS_IN_ENV is defined. +If CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE is defined, console_overwrite() decides if the +values stored in the environment or the standard serial in/output should be +assigned to the console. This is useful if the environment values are not correct. +If CONFIG_SYS_CONSOLE_ENV_OVERWRITE is defined the devices assigned to the console at +start-up time will be written to the environment. This means that if the +environment values are overwritten by the overwrite_console() routine, they will be +stored in the environment. +Changed files: +- common/console.c + +Correct bootdelay intepretation: +-------------------------------- +Changed bootdelay read from the environment from simple_strtoul (unsigned) to +simple_strtol (signed), to be able to get a bootdelay of -1. +Changed files: +- common/main.c + +Todo: +===== + +Block device support enhancement: +--------------------------------- +Consider to unify the block device handling. Instead of using diskboot for IDE, +scsiboot for SCSI and fdcboot for floppy disks, it would make sense to use only +one command ("devboot" ???) with a parameter of the desired device ("hda1", "sda1", +"fd0" ???) to boot from. The other ide commands can be handled in the same way +("dev hda read.." instead of "ide read.." or "dev sda read.." instead of +"scsi read..."). Todo this, a common way of assign a block device to its name +(first found ide device = hda, second found hdb etc., or hda is device 0 on bus 0, +hdb is device 1 on bus 0 etc.) as well as the names (hdx for ide, sdx for scsi, fx for +floppy ???) must be defined. +Maybe there are better ideas to do this. + +Console assingment: +------------------- +Consider to initialize and assign the console stdin, stdout and stderr as soon as +possible to see the boot messages also on an other console than serial. + + +Todo for PIP405: +================ + +LCD support for VGA: +-------------------- +Add LCD support for the CT69000 + +Default environment: +-------------------- +Consider to write a default environment to the OTP part of the EEPROM and use it +if the normal environment is not valid.

U-Boot support +for this board is heavily based on the existing U-Boot support for +Freescale MPC8349 reference boards. + +Support has been primarily tested on the SBC8349 version of the board, +although earlier versions were also tested on the SBC8347. The primary +difference in the two is the level of PCI functionality. + + http://www.windriver.com/products/OCD/SBC8347E_49E/ + + +Flash Details: +============== + +The flash type is intel 28F640Jx (4096x16) [one device]. Base address +is 0xFF80_0000 which is also where the Hardware Reset Configuration +Word (HRCW) is stored. Caution should be used to not reset the +board without having a valid HRCW in place (i.e. erased flash) as +then a Wind River ICE will be required to restore the HRCW and flash +image. + + +Restoring a corrupted or missing flash image: +============================================= + +Note that U-boot versions up to and including 2009.06 had essentially +two copies of u-boot in flash; one at the very beginning, which set +the HRCW, and one at the very end, which was the image that was run. +As of this point in time, the two have been combined into just one +at the beginning of flash, which provides both the HRCW, and the image +that is executed. This frees up the remainder of flash for other uses. +Use of the u-boot command "fli" will indicate what parts are in use. +Details for storing U-boot to flash using a Wind River ICE can be found +on page 19 of the board manual (request ERG-00328-001). The following +is a summary of that information: + + - Connect ICE and establish connection to it from WorkBench/OCD. + - Ensure you have background mode (BKM) in the OCD terminal window. + - Select the appropriate flash type (listed above) + - Prepare a u-boot image by using the Wind River Convert utility; + by using "Convert and Add file" on the ELF file from your build. + Convert from FF80_0000 to FFFF_FFFF (or to FF83_FFFF if you are + trying to preserve your old environment settings and user flash). + - Set the start address of the erase/flash process to FF80_0000 + - Set the target RAM required to 64kB. + - Select sectors for erasing (see note on enviroment below) + - Select Erase and Reprogram. + +Note that some versions of the register files used with Workbench +would zero some TSEC registers, which inhibits ethernet operation +by u-boot when this register file is played to the target. Using +"INN" in the OCD terminal window instead of "IN" before the "GO" +will not play the register file, and allow u-boot to use the TSEC +interface while executed from the ICE "GO" command. + +Alternatively, you can locate the register file which will be named +WRS_SBC8349_PCT00328001.reg or similar) and "REM" out all the lines +beginning with "SCGA TSEC1" and "SCGA TSEC2". This allows you to +use all the remaining register file content. + +If you wish to preserve your prior U-Boot environment settings, +then convert (and erase to) 0xFF83FFFF instead of 0xFFFFFFFF. +The size for converting (and erasing) must be at least as large +as u-boot.bin. + + +Updating U-Boot with U-Boot: +============================ + +This procedure is very similar to other boards that have u-boot installed. +Assuming that the network has been configured, and that the new u-boot.bin +has been copied to the TFTP server, the commands are: + + tftp 200000 u-boot.bin + protect off all + erase ff800000 ff83ffff + cp.b 200000 ff800000 40000 + protect on all + +You may wish to do a "md ff800000 20" operation as a prefix and postfix +to the above steps to inspect/compare the HRCW before/after as an extra +safety check before resetting the board upon completion of the reflash. + +PCI: +==== + +There are three configuration choices: + sbc8349_config + sbc8349_PCI_33_config + sbc8349_PCI_66_config + +The 1st does not enable CONFIG_PCI, and assumes that the PCI slot +will be left empty (M66EN high), and so the board will operate with +a base clock of 66MHz. Note that you need both PCI enabled in u-boot +and linux in order to have functional PCI under linux. The only +reason for choosing to not enable PCI would be if you had a very +early (rev 1.0) CPU with possible PCI issues. + +The second enables PCI support and builds for a 33MHz clock rate. Note +that if a 33MHz 32bit card is inserted in the slot, then the whole board +will clock down to a 33MHz base clock instead of the default 66MHz. This +will change the baud clocks and mess up your serial console output if you +were previously running at 66MHz. If you want to use a 33MHz PCI card, +then you should build a U-Boot with sbc8349_PCI_33_config and store this +to flash prior to powering down the board and inserting the 33MHz PCI +card. + +The third option builds PCI support in, and leaves the clocking at the +default 66MHz. This has been tested with an intel PCI-X e1000 card. +This is also the appropriate choice for people with a recent (non 1.0) +CPU who currently have the PCI slot physically empty, but intend to +possibly add a PCI-X card at a later date. + + => pci + Scanning PCI devices on bus 0 + BusDevFun VendorId DeviceId Device Class Sub-Class + _____________________________________________________________ + 00.00.00 0x1957 0x0080 Processor 0x20 + 00.11.00 0x8086 0x1026 Network controller 0x00 + => diff --git a/board/sbc8548/README b/board/sbc8548/README new file mode 100644 index 0000000..feac5e3 --- /dev/null +++ b/board/sbc8548/README @@ -0,0 +1,269 @@ +Intro: +====== + +The SBC8548 is a stand alone single board computer with a 1GHz +MPC8548 CPU, 8MB boot flash, 64MB user flash and, 256MB DDR2 400MHz +memory.

It does not by default use the DDR2 SPD +EEPROM data to read what memory is installed. + +There is a hardware errata, which causes the older local bus SDRAM +SPD EEPROM to land at the same address as the DDR2 SPD EEPROM, so +that the SPD data can not be read reliably. You can test if your +board has the errata fix by running "i2c probe". If you see 0x53 +as a valid device, it has been fixed. If you only see 0x50, 0x51 +then your board does not have the fix. + +You can also visually inspect the board to see if this hardware +fix has been applied: + + 1) Remove R314 (RES-R0174-033, 1K, 0603). R314 is located on + the back of the PCB behind the DDR SDRAM SODIMM connector. + 2) Solder RES-R0174-033 (1K, 0603) resistor from R314 pin 2 pad + to R313 pin 2. Pin 2 for each resistor is the end of the + resistor closest to the CPU. + +Boards without the mod will have R314 and R313 in parallel, like "||". +After the mod, they will be touching and form an "L" shape. + +If you want to upgrade to larger RAM size, you can simply enable + #define CONFIG_SPD_EEPROM + #define CONFIG_DDR_SPD +in include/configs/sbc8548.h file. (The lines are already there +but listed as #undef). + +If you did the i2c test, and your board does not have the errata +fix, then you will have to physically remove the LBC 128MB DIMM +from the board's socket to resolve the above i2c address overlap +issue and allow SPD autodetection of RAM to work. + + +Updating U-boot with U-boot: +============================ + +Note that versions of u-boot up to and including 2009.08 had u-boot stored +at 0xfff8_0000 -> 0xffff_ffff (512k). Currently it is being stored from +0xfffa_0000 -> 0xffff_ffff (384k). If you use an old macro/script to +update u-boot with u-boot and it uses the old address, you will render +your board inoperable, and you will require JTAG recovery. + +The following steps list how to update with the current address: + + tftp u-boot.bin + md 200000 10 + protect off all + erase fffa0000 ffffffff + cp.b 200000 fffa0000 60000 + md fffa0000 10 + protect on all + +The "md" steps in the above are just a precautionary step that allow +you to confirm the u-boot version that was downloaded, and then confirm +that it was copied to flash. + +The above assumes that you are using the default board settings which +have u-boot in the 8MB flash, tied to /CS0. + +If you are running the default 8MB /CS0 settings but want to store an +image in the SODIMM that is built with CONFIG_SYS_ALT_BOOT enabled, +(as a backup, etc) then the steps will become: + + tftp u-boot.bin + md 200000 10 + protect off all + era eff00000 efffffff + cp.b 200000 eff00000 100000 + md eff00000 10 + protect on all + +Finally, if you are running the alternate 64MB /CS0 settings and want +to update the in-use u-boot image, then (again with CONFIG_SYS_ALT_BOOT +enabled) the steps will become: + + tftp u-boot.bin + md 200000 10 + protect off all + era fff00000 ffffffff + cp.b 200000 fff00000 100000 + md fff00000 10 + protect on all + + +Hardware Reference: +=================== + +The following contains some summary information on hardware settings +that are relevant to u-boot, based on the board manual.

On the debug board, dips 1 and 7 should be on with the rest off. +The serial console has been set up to run from the DB9 connector on the +P2 board at 115200 baud, 8 data bits, no stop bits, 1 parity bit. + + It should be noted that the P2 board has NOR flash that is addressable via +either CS0 or CS3. This mode can be changed via DIP9 on the P2 board. + + +Installing u-boot for the P2 : + + You can simply build u-boot for the Perseus by following the instructions +in the main readme file. The target configuration is "omap730p2_config". +Once u-boot has been built, you should strip the executable so it can be +loaded via CCS (which cant cope with the symbols in the ELF binary) : + $ cp u-boot u-boot.out + $ arm-linux-strip u-boot.out + + The method we've used for installing u-boot the first time on a P2 is +as follows : + +1) Configure TI Code Composer Studio to connect to the P2 board via JTAG + as described in the Users Guide. + +2) Set up the P2 to boot from CS3, and connect with CCS. Reset the CPU + and run the "init_mmu" GEL script. + +3) Use the "Load Program" option to send the u-boot.out file to the P2 and + run. + + At this point, u-boot should run and you will see the boot menu on your +serial terminal.

However, you can set DIP9 to off to swap the boot mode +of the P2 so that you boot from RAM instead of NOR flash. This moves NOR +flash up to 0x0C000000. You can build a special version of u-boot to +utilise this by the following config : + + $ make omap730p2_cs0boot_config + + If you load this up via CCS it will detect flash at its alternate location +and allow you to programme your u-boot image (which, remember must be built +for CS3 boot!) Once you do this, you can revert to CS3 boot and it will work +fine again. + + +Errata : + +1) It's been observed that sometimes the tftp transfer of kernels to the + board can have checksum errors or stall.

The first page (256 bytes) contains the +strappings and the 2 EMAC HW Ethernet addresses. Be careful not to +change the 1st page of the EEPROM!
