[U-Boot] ocotp

[Nogradi Peter]

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
