Hi,
I am trying to leave the Windows-World and change to Linux.
Unfortunately I have some problems erasing the memory of some flash-PICs
using PICP.
If I take a new PIC everythink is OK until the first programming. After
that erasing is not possible:
svebra@linux:~> picp /dev/ttyS0 12f629 -s -ep
########################################
program memory: not blank
failed to erase program space
svebra@linux:~> picp /dev/ttyS0 12f629 -s -ep
And if I readout the PIC there ist still the code in the memory.
I tried with some 12F629 and a 16F629 and I used different wirings...
It seems to have nothing to do with the configuration-Bits.
I read that there was a discussion in Nov.02 about it. Is there a solution?
If I set the code protection bit, the memory should be erased. This is
also not the case.
Hope to get an answer
Sven
