I found an email that discussed the similar problem that my camera had, showing up just a black screen, it's dated but i think maybe it wasn't fully solved because there's no answer.


Note the : ">/ > /Vimicro/zc3xx.h: [zcxx_probeSensor:307] sensor 3w Vga ??? 0xC400"

/Do you know if this was solved?!
Because i suspect that maybe there are more 0x?400 revision of the chipset.
Btw, if this is a pattern could we consider to mask the bits in retword (retword &= 0x0FFF)?
Because looking at the current table it seems to make more sense.

Best regards,
Luis Maia.

Hello Luis and Leandro,

Thanks for the patch. Luis said his sensor is the tas5130K, so the 2nd
part of the patch is useless. But, maybe, Leandro, have you heard about
other chipset revision IDs?

Best regards.
