Hi,

we have a m28evk custom board from Fa. Denx, (ELDK 5.4) it worked properly, until I wrote a word with u-boot fuse prog.
fuse prog 0 4 1
(it was my mistake, i wanted to test the fuse prog to the customer area (for example: fuse prog 0 2 1)
Until fuse prog I can't boot. (Neither SDcard nor NAND flash) I get only the message
0x50801006
What can I do now, and theoretically where can I write data (I know only once) for example serial number, etc

Thanks in advance and best regards
Peter Nogradi
