Hi,
I don't know what you are going to do but the "rb" in front of the
"\xff{256}" seems odd. I only know of a "r" prefix.
I would try: if re.match(r"\xff{256}", chunk):

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.

I don't think that VID PID pair is supported. It would be nice if
PulseView could let you add VID PID easily but I think it needs
re-compile.
You could change VID PID of your device to a supported one which
is listed here:
src/hardware/fx2lafw/api.c
https://sigrok.org/gitweb/?p=libsigrok.git;a=blob;f=src/hardware/fx2lafw/api.c;h=5acb0016d0b8e6ab5ad204aea7e238f55e2f5fa8;hb=HEAD
<https://sigrok.org/gitweb/?p=libsigrok.git;a=blob;f=src/hardware/fx2lafw/api.c;h=5acb0016d0b8e6ab5ad204aea7e238f55e2f5fa8;hb=HEAD>
e.g. first option is 0x08a9, 0x0014
You might be able to use the python fx2tool to change VID PID
https://github.com/whitequark/libfx2
<https://github.com/whitequark/libfx2>
|pip install fx2|
|fx2tool -B -d 16c0:296d read_eeprom -W 1 0 256|
|fx2tool -B -d 16c0:296d read_eeprom -W 1 -f eeprom.bin 0 256 save
copy of eeprom.bin, modify VID PID, then: |
|fx2tool -B -d 16c0:296d write_eeprom -W 1 -a 0 -f
./eeprom-new.bin unplug/re-plug, should be new VID PID now|
Maybe someone knows easier way?

Hi folks,
I'm trying to run geeetech CY7C68013A LA on sigrok/pulseview on
ubuntu 18.04 but it is not being detected.
$ sudo sigrok-cli -d fx2lafw --scan
returns nothing (as superuser or normal user).
dmesg returns:
