323. Definitions

343.1 Explanation of NEW definitions in:
35
36 include/configs/MPC8313ERDB.h
37
38 CONFIG_MPC83xx MPC83xx family
39 CONFIG_MPC831x MPC831x specific
40 CONFIG_MPC8313ERDB MPC8313ERDB board specific
41
424. Compilation
43
44 Assuming you're using BASH (or similar) as your shell:
45
46 export CROSS_COMPILE=your-cross-compiler-prefix-
47 make distclean
48 make MPC8313ERDB_33_config
49 (or make MPC8313ERDB_66_config, depending on the speed of
50 the oscillator on your board)
51 make
52
535. Downloading and Flashing Images
54
555.1 Reflash U-boot Image using U-boot
56
57 =>run tftpflash
58
59 You may want to try
60 =>tftpboot $loadaddr $uboot
61 first, to make sure that the TFTP load will succeed before it
62 goes ahead and wipes out your current firmware. And of course,
63 have an alternate means of programming the flash available
64 if the new u-boot doesn't boot.
65
665.2 Downloading and Booting Linux Kernel
67
68 Ensure that all networking-related environment variables are set
69 properly (including ipaddr, serverip, gatewayip (if needed),
70 netmask, ethaddr, eth1addr, rootpath (if using NFS root),
71 fdtfile, and bootfile).
72
73 Then, do one of the following, depending on whether you
74 want an NFS root or a ramdisk root:
75
76 =>run nfsboot
77 or
78 =>run ramboot

806 Notes
81
82 Booting from NAND flash is not yet supported.
83 The console baudrate for MPC8313ERDB is 115200bps.
