Thank you Kevin for the fast response.
This solution was very clever and promising but I got a frustrating error
from fx2tool related to its syntax:
"
Traceback (most recent call last):
File "/usr/local/bin/fx2tool", line 5, in <module>
from fx2.fx2tool import main
File "/usr/local/lib/python2.7/dist-packages/fx2/fx2tool.py", line 327
if re.match(rb"\xff{256}", chunk):
^
SyntaxError: invalid syntax
"
I didn't find any help on this on google.
If you or someone else now how to run, in other program, the sequence of
save the eeprom content, change the VID PID and reflash I would gratefully
try it as well. Unfortunately this world of reading and writing firmwares
to eeproms manually is kind of new to me.
Thank you in advance.
Fausto.
