hi,all i want to boot kernel from flash on TI p2-sample rev.6 board. i used:
1. erase 0x100000 0x3fffff (0x100000--0x3fffff is flash room for kernel) 2. loadb 0x100000 3. using kermit to transfer uImage from ttyS0 4. using "iminfo 0x100000", and i found "Bad Magic Number" 5. setenv bootcmd bootm 0x100000 6. boot, but i found "## Booting image at 00100000 ... Bad Magic Number"
i used this uImage file to boot kernel from memory, so kernel image is right! and i tried to use "tftp 0x100000" to download image to flash,and the result is identical.
and i did more testing: 1. tftp 0x10000000 (0x10000000 is ram address) 2. erase 0x100000 0x3fffff 3. cp.b 0x10000000 0x100000 $(filesize) 4. bootm 0x100000
the kernel boot successed! but if i rebooted, and "bootm 0x100000", the kernel stoped when mounted nfsroot fs. the boot information was: .............................. <6>Freeing initrd memory: 4096K Freeing initrd memory: 4096K <5>Looking up port of RPC 100003/2 on 172.16.6.79 Looking up port of RPC 100003/2 on 172.16.6.79
(172.16.6.79 is nfsroot server)
so, what's wrong with it?
thank you!
