- Freescale MPC8313ERDB Board
- -----------------------------------------
- 1. Board Switches and Jumpers
- S3 is used to set CFG_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.)
- 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
- 0xe200_0000 0xe20f_ffff PCI IO 16M
- 0xe280_0000 0xe280_7fff NAND FLASH (CS1) 32K
- 0xf000_0000 0xf001_ffff VSC7385 (CS2) 128K
- 0xfa00_0000 0xfa00_7fff Board Status/ 32K
- LED Control (CS3)
- 0xfe00_0000 0xfe7f_ffff NOR FLASH (CS0) 8M
- 3. Definitions
- 3.1 Explanation of NEW definitions in:
- include/configs/MPC8313ERDB.h
- CONFIG_MPC83xx MPC83xx family
- CONFIG_MPC831x MPC831x specific
- CONFIG_MPC8313ERDB MPC8313ERDB board specific
- 4. Compilation
- Assuming you're using BASH (or similar) as your shell:
- export CROSS_COMPILE=your-cross-compiler-prefix-
- make distclean
- make MPC8313ERDB_33_config
- (or make MPC8313ERDB_66_config, depending on the speed of
- the oscillator on your board)
- make
- 5. Downloading and Flashing Images
- 5.1 Reflash U-boot Image using U-boot
- =>run tftpflash
- You may want to try
- =>tftpboot $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,
- have an alternate means of programming the flash available
- if the new u-boot doesn't boot.
- 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
- Booting from NAND flash is not yet supported.
- The console baudrate for MPC8313ERDB is 115200bps.
