-Freescale MPC8315ERDB Board
------------------------------------------
-
-1. Board Switches and Jumpers
-
- S3 is used to set CONFIG_SYS_RESET_SOURCE.
-
- To boot the image at 0xFE000000 in NOR flash, use these DIP
- switch settings for S3 S4:
-
- +------+ +------+
- | | | **** |
- | **** | | |
- +------+ ON +------+ ON
- 4321 4321
- (where the '*' indicates the position of the tab of the switch.)
-
- To boot the image at the beginning of NAND flash, use these
- DIP switch settings for S3 S4:
-
- +------+ +------+
- | * | | *** |
- | *** | | * |
- +------+ ON +------+ ON
- 4321 4321
- (where the '*' indicates the position of the tab of the switch.)
-
- When booting from NAND, use u-boot-nand.bin, not u-boot.bin.
-
-2. Memory Map
- The memory map looks like this:
-
- 0x0000_0000 0x07ff_ffff DDR 128M
- 0x8000_0000 0x8fff_ffff PCI MEM 256M
- 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
- 0xe000_0000 0xe00f_ffff IMMR 1M
- 0xe030_0000 0xe03f_ffff PCI IO 1M
- 0xe060_0000 0xe060_7fff NAND FLASH (CS1) 32K
- 0xfe00_0000 0xfe7f_ffff NOR FLASH (CS0) 8M
-
- When booting from NAND, NAND flash is CS0 and NOR flash
- is CS1.
-
-3. Definitions
-
-3.1 Explanation of NEW definitions in:
-
- include/configs/MPC8315ERDB.h
-
- CONFIG_MPC83xx MPC83xx family
- CONFIG_MPC831x MPC831x specific
- CONFIG_MPC8315 MPC8315 specific
- CONFIG_MPC8315ERDB MPC8315ERDB board specific
-
-4. Compilation
-
- Assuming you're using BASH (or similar) as your shell:
-
- export CROSS_COMPILE=your-cross-compiler-prefix-
- make distclean
- make MPC8315ERDB_config (or MPC8315ERDB_NAND_config for u-boot-nand.bin)
- make all
-
-5. Downloading and Flashing Images
-
-5.1 Reflash U-boot Image using U-boot
-
- NOR flash:
-
- tftp 40000 u-boot.bin
- protect off all
- erase fe000000 fe1fffff
-
- cp.b 40000 fe000000 xxxx
- protect on all
-
- You have to supply the correct byte count with 'xxxx'
- from the TFTP result log.
-
- NAND flash:
-
- =>tftpboot $loadaddr <filename>
- =>nand erase 0 0x80000
- =>nand write $loadaddr 0 0x80000
-
- ...where 0x80000 is the filesize rounded up to
- the next 0x20000 increment.
-
-5.2 Downloading and Booting Linux Kernel
-
- Ensure that all networking-related environment variables are set
- properly (including ipaddr, serverip, gatewayip (if needed),
- netmask, ethaddr, eth1addr, rootpath (if using NFS root),
- fdtfile, and bootfile).
-
- Then, do one of the following, depending on whether you
- want an NFS root or a ramdisk root:
-
- =>run nfsboot
- or
- =>run ramboot
-
-6 Notes
-
- The console baudrate for MPC8315ERDB is 115200bps.
