- Freescale MPC8323ERDB Board
- -----------------------------------------
- 1. Memory Map
- The memory map looks like this:
- 0x0000_0000 0x03ff_ffff DDR 64M
- 0x8000_0000 0x8fff_ffff PCI MEM 256M
- 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
- 0xe000_0000 0xe00f_ffff IMMR 1M
- 0xd000_0000 0xd3ff_ffff PCI IO 64M
- 0xfe00_0000 0xfeff_ffff NOR FLASH (CS0) 16M
- 2. Compilation
- Assuming you're using BASH (or similar) as your shell:
- export CROSS_COMPILE=your-cross-compiler-prefix-
- make distclean
- make MPC8323ERDB_config
- make
- 3. Downloading and Flashing Images
- 3.1 Reflash U-Boot Image using U-Boot
- N.b, have an alternate means of programming
- the flash available if the new U-Boot doesn't boot.
- First try a:
- tftpboot $loadaddr $uboot
- to make sure that the TFTP load will succeed before
- an erase goes ahead and wipes out your current firmware.
- Then do a:
- run tftpflash
- which is a shorter version of the manual sequence:
- tftp $loadaddr u-boot.bin
- protect off fe000000 +$filesize
- erase fe000000 +$filesize
- cp.b $loadaddr fe000000 $filesize
- To keep your old U-Boot's environment variables, do a:
- saveenv
- prior to resetting the board.
- 3.2 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
- 4 Notes
- The console baudrate for MPC8323ERDB is 115200bps.
