Freescale MPC8313ERDB Board
-----------------------------------------
1. Board Switches and Jumpers
SW3 is used to set CFG_RESET_SOURCE.
To boot the image at 0xFE000000 in NOR flash, use these DIP
switche settings for SW3 SW4:
+------+ +------+
| | | **** |
| **** | | |
+------+ 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.
