-Sheldon Instruments SIMPC8313 Board
------------------------------------------
-
-1. Board Switches and Jumpers
-
- S2 is used to set CFG_RESET_SOURCE.
-
- To boot the image in Large page NAND flash, use these DIP
- switch settings for S2:
-
- +----------+ ON
- | * * **** |
- | * * |
- +----------+
- 12345678
-
- To boot the image in Small page NAND flash, use these DIP
- switch settings for S2:
-
- +----------+ ON
- | *** **** |
- | * |
- +----------+
- 12345678
- (where the '*' indicates the position of the tab of the switch.)
-
-2. Memory Map
- The memory map looks like this:
-
- 0x0000_0000 0x1fff_ffff DDR 512M
- 0x8000_0000 0x8fff_ffff PCI MEM 256M
- 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
- 0xe000_0000 0xe00f_ffff IMMR 1M
- 0xe200_0000 0xe20f_ffff PCI IO 16M
- 0xe280_0000 0xe280_7fff NAND FLASH (CS0) 32K
- or
- 0xe280_0000 0xe281_ffff NAND FLASH (CS0) 128K
- 0xff00_0000 0xff00_7fff FPGA (CS1) 1M
-
-3. Compilation
-
- Assuming you're using BASH (or similar) as your shell:
-
- export CROSS_COMPILE=your-cross-compiler-prefix-
- make distclean
- make SIMPC8313_LP_config
- (or make SIMPC8313_SP_config, depending on the page size
- of your NAND flash)
- make
-
-4. Downloading and Flashing Images
-
-4.1 Reflash U-boot Image using U-boot
-
- =>run update_uboot
-
- You may want to try
- =>tftp $loadaddr $uboot
- first, to make sure that the TFTP load will succeed before it
- goes ahead and wipes out your current firmware. And of course,
- if the new u-boot doesn't boot, you can plug the board into
- your PCI slot and with the supplied driver and sample app
- you can reburn a working u-boot.
-
-4.2 Downloading and Booting Linux Kernel
-
- Ensure that all networking-related environment variables are set
- properly (including ipaddr, serverip, gatewayip (if needed),
- netmask, ethaddr, eth1addr, fdtfile, and bootfile).
-
- =>tftp $loadaddr uImage
- =>nand write $loadaddr kernel $filesize
- =>tftp $loadaddr $fdtfile
- =>nand write $loadaddr 7e0000 1800
-
- =>boot

-5 Notes
-
- The console baudrate for SIMPC8313 is 115200bps.
