Re: Very strange: fis create/write fail Err = 92


Yes, I have try. I just can write a single block of the flash after unlock a single.
I can't write two more continuous blocks in the same time.
what is reason ? I don't think it is hw problem. do you ?

When you unlock a single block of the flash, can you successfully write to
it?
If you can do this, but failed to unlock two more continuous blocks and
write to them, I think there may be something wrong with the lock/unlock
procedure.
