For general Nios +information see doc/README.nios. + +Most stuff of this file was borrowed and based on README.dk1c20, +the DK-1C20 related information file. + +For those interested in contributing ... see HELP WANTED section +in doc/README.nios. + +Contents: + + 1.

Files +========= + board/altera/dk1s10/* + include/configs/DK1S10.h + +2. Memory Organization +======================= + + -The heap is placed below the monitor (U-Boot code). + -Global data is placed below the heap. + -The stack is placed below global data (&grows down). + +3. CPU Variations +================= + +There are more than one NIOS CPU variation for the DK-1S10. U-Boot +supports the following CPU configurations: + + - Altera Standard 32 (make DK1S10_standard_32_config) + - Microtronix LDK 2.0 (make DK1S10_mtx_ldk_20_config) + +4. Examples +============ + +The hello_world example was never tested on DK-1S10. Neverthelse +it should work as far as possible, because the DK-1S10 port is +more than ninetieth percents equal to the DK-1C20 port and at +this platform the hello_world example was already tested +successfully (see README.dk1c20). + + +5. Programming U-Boot into FLASH with GERMS +============================================ +The current version of the DK-1S10 port with the default +configuration settings occupies about 78 KBytes of flash. +A minimal configuration occupies less than 60 KByte +(network support disabled). + +To program U-Boot into the DK-1S10 flash using GERMS do the +following: + +1. From the command line, download U-Boot using the nios-run: + + $ nios-run -r u-boot.srec + +This takes about 45 seconds (GERMS is not very speedy here). +After u-boot is downloaded it will be executed. You should +see the following: + + U-Boot 1.0.2 (Jan 28 2004 - 19:02:30) + + CPU: Nios-32 Rev. 3.3 (0x3038) + Reg file size: 256 LO_LIMIT/HI_LIMIT: 2/14 + Board: Altera Nios 1S10 Development Kit + In: serial + Out: serial + Err: serial + DK1S10 > + + +2. Quit nios-run and start your terminal application (e.g. start + Hyperterminal or minicom). + +3. Download the u-boot code to RAM. When using Hyperterminal, do the + following: + + a. From the u-boot command prompt start a binary download to + SRAM / SDRAM: + + at the Altera Standard 32 to SRAM: + + ==> loadb 800000 + + at the Microtronix LDK 2.0 to SDRAM: + + ==> loadb 1010000 + + b. Download u-boot.bin using kermit. + +4. From the U-Boot command prompt, erase flash: + + at the Altera Standard 32 from 0x40000 to 0x5ffff: + + ==> erase 1:4-5 + + at the Microtronix LDK 2.0 from 0x8000000 to 0x81ffff: + + ==> erase 1:0-1 + +5. Copy the binary image from SRAM / SDRAM to flash: + + at the Altera Standard 32 to SRAM: + + ==> cp.b 800000 40000 $(filesize) + + at the Microtronix LDK 2.0 to SDRAM: + + ==> cp.b 1010000 8000000 $(filesize) + +U-Boot will now automatically start when the board is powered on or +reset using the Standard-32 configuration. To start U-Boot with the +Safe-32 configuration, enter the following GERMS command: + + + g 40000 |
