41. Memory Map
5 The memory map looks like this:
6
7 0x0000_0000 0x03ff_ffff DDR 64M
8 0x8000_0000 0x8fff_ffff PCI MEM 256M
9 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
10 0xe000_0000 0xe00f_ffff IMMR 1M
11 0xd000_0000 0xd3ff_ffff PCI IO 64M
12 0xfe00_0000 0xfeff_ffff NOR FLASH (CS0) 16M

142. Compilation
15
16 Assuming you're using BASH (or similar) as your shell:
17
18 export CROSS_COMPILE=your-cross-compiler-prefix-
19 make distclean
20 make MPC8323ERDB_config
21 make

233. Downloading and Flashing Images

Bin Menga1875592016-02-05 19:30:11 -0800253.1 Reflash U-Boot Image using U-Boot
Kim Phillips1c274c42007-07-25 19:25:33 -050026
27 N.b, have an alternate means of programming
Bin Menga1875592016-02-05 19:30:11 -080028 the flash available if the new U-Boot doesn't boot.
Kim Phillips1c274c42007-07-25 19:25:33 -050029
30 First try a:
31
32 tftpboot $loadaddr $uboot
33
34 to make sure that the TFTP load will succeed before
35 an erase goes ahead and wipes out your current firmware.
36 Then do a:
37
38 run tftpflash
39
40 which is a shorter version of the manual sequence:
41
42 tftp $loadaddr u-boot.bin
43 protect off fe000000 +$filesize
44 erase fe000000 +$filesize
45 cp.b $loadaddr fe000000 $filesize
46
Bin Menga1875592016-02-05 19:30:11 -080047 To keep your old U-Boot's environment variables, do a:
Kim Phillips1c274c42007-07-25 19:25:33 -050048
49 saveenv
50
51 prior to resetting the board.
52
533.2 Downloading and Booting Linux Kernel
54
55 Ensure that all networking-related environment variables are set
56 properly (including ipaddr, serverip, gatewayip (if needed),
57 netmask, ethaddr, eth1addr, rootpath (if using NFS root),
58 fdtfile, and bootfile).
59
60 Then, do one of the following, depending on whether you
61 want an NFS root or a ramdisk root:
62
63 run nfsboot
64
65 or
66
67 run ramboot
