Hi,
Ignore fw_info. It knows about such a small fraction of the registers it
can be ignored.
In fact, I've just removed it, it only confuses.
The old extractor was floored in the way if found firmware, that's why
it's dumped.
In the git repos now, there is only fw_extractor.py which is the new one
replacing the old.
As to which firmware to use, the only way is suck and see for each. :-\
Hope this helps.

Hello,
I tried extracting firmware from my pmp3670b tablet and I got 4
firmware files with fw_extractor2.py. Unfortunately, fw_info does not
recognize any of them as firmware:

I have old firmware extracted from my broken inet 86vs tablet and from

are recognized as firmware:

However, the old extractor does not seem to like the pmp3670b module.
I never get any firmware out of it.
Any suggestions?
Thanks

Hi Kristijan,
Not sure quite what your after, but here is a new, not tested yet (would
have to dig up the tablet), firmware extractor.
It uses just readelf, objcopy and dd. Quick and dirty "python for shell"
implementation.
Hopefully this should help.

Hello,
attached is a gslX680.ko module from a Q88 A23 based tablet (the cheap USD
32 devices) I just started to extract the firmware to use gsl1680 IC with
the touch panels that are used in this Q88 devices.
I think "GSL1680_K70_FW" should be the one. from this module.
Attached is also a small PCB design made in eagle to make test connection
between that touch panels and I2C interface. Maybe it is useful for someone.
