The initial +bootloader which executes upon reset is the ROM Boot Loader (RBL) and sits +in the internal ROM. The RBL initializes the internal memory and then +depending on the exact board and pin configurations will initialize another +controller (such as NAND) to continue the boot process by loading +the secondary program loader (SPL). The SPL will initialize the system +further (some clocks, SDRAM). As on this board is used the falcon boot +mode, now 2 ways are possible depending on the GPIO 7_14 input pin, +connected with the "soft reset switch" + +If this pin is logical 1 (high level): +spl code starts the kernel image without delay + +If this pin is logical 0 (low level): +spl code starts the u-boot image + +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 AIS format allows for +other things such as programming the clocks and SDRAM if the header is +programmed for it. We do not take advantage of this and instead use SPL as +it allows for additional flexibility (run-time detect of board revision, +loading the next image from a different media, etc). + +Compilation +=========== +run "./MAKEALL ipam390" in the u-boot source tree. +Once this build completes you will have a u-boot.ais file that needs to +be written to the nand flash. + +Flashing the images to NAND +========================== +The AIS image can be written to NAND flash using the following commands. +Assuming that the network is configured and enabled and the u-boot.ais file +is tftp'able. + +U-Boot > print upd_uboot +upd_uboot=tftp c0000000 ${u-boot};nand erase.part u-boot;nand write c0000000 20000 ${filesize} +U-Boot > +U-Boot > run upd_uboot +Using DaVinci-EMAC device +TFTP from server 192.168.1.1; our IP address is 192.168.20.71 +Filename '/tftpboot/ipam390/u-boot.ais'. +Load address: 0xc0000000 +Loading: ################################## + 1.5 MiB/s +done +Bytes transferred = 493716 (78894 hex) + +NAND erase.part: device 0 offset 0x20000, size 0x160000 +Erasing at 0x160000 -- 100% complete. +OK + +NAND write: device 0 offset 0x20000, size 0x78894 + 493716 bytes written: OK +U-Boot > + +Recovery +======== + +In the case of a "bricked" board, you need to use the TI tools found +here[1] to create an uboot-uart-ais.bin file + +- cd to the u-boot source tree + +- compile the u-boot for the ipam390 board: +$ ./MAKEALL ipam390 + + -> Now we shall have u-boot.bin + +- Create u-boot-uart-ais.bin +$ mono HexAIS_OMAP-L138.exe -entrypoint 0xC1080000 -ini +ipam390-ais-uart.cfg -o ./uboot-uart-ais.bin ./u-boot.bin@0xC1080000; + +Note: The ipam390-ais-uart.cfg is found in the board directory +for the ipam390 board, u-boot:/board/Barix/ipam390/ipam390-ais-uart.cfg + +- We can now run bootloader on IPAM390 via UART using the command below: + +$ mono ./slh_OMAP-L138.exe -waitForDevice -v -p /dev/tty.UC-232AC uboot-uart-ais.bin +NOTE: Do not cancel the command execution!
