Thanks, Phil. But when I power on DM355 EVM, and abort the automatic boot
sequence by pressing a key in the console window, use your suggestion,
setenv bootcmd nboot 0x80700000 0 0x400000; bootm
I got,
## Booting image at 80700000 ...
Bad Magic Number
I think I did the right thing - break into the u-boot sequence and tried to
restore the original value of bootcmd, but it seems the board did not like
it... Any more suggestions?
Cheers,
Michael
