Don't feel down about this, this is always difficult and you are making
good progress already.

Very nice. I assume you can read the chip id and that's good, it means
that SDIO bus is working correctly.

Current wl12xx code assumes that user space provides the NVS file. I'm
guessing that Android has NVS file stored in chip's EEPROM. Check the
!pWhalBus->pEEPROMBuf code path from TI's driver how to implement it.
Should be relatively easy:

Please let me know if you have any questions. I try to get hold of
pandora, it has wl1251 using SDIO, so that I could help you with
testing.
