[HELP]: Wrong u_boot into flash

[solala]

what about the preset uboot... are the uboot commands working? try

print

and post the output here. try

help

and post the output here. try

fatload usb 0:1 80000000 anyfile.bin

where anyfile.bin has to be a file of a few kbyte in the root directory of an attached fat32 usb stick.
if those things are working it might be possible to flash the original uboot just by a few commands in the serial console
