Thanks,
Am I understand right - all I need - it is just open .ko file, jumb to
symbols page and choose needed variable (4ex:
GSLX680_FW_I81_GSL3676B_8001280_OGS_SG) and choose "export to binary" and
as result I will get my firmware?
In that case = declarations exists in .rodata and .data. ;-) of course I
will try both, but would like to understand = which is correct.
Regards,
Serge.
