raspberry pi pico w support? #81

Open shuffle2 opened 4 months ago

shuffle2 commented 4 months ago

The fw file for pico w starts with: FCYW4343A2_001.003.016.0031.0000_Generic_SDIO_37MHz_wlbga_BU_dl_signed.

Read_RAM returns status 0x12 for all addresses.

Is there a way to get this to work? Can I load a different fw? Can it be patched somehow (or is it really sig checked?)? Any other workarounds?

well, i wrote a little parser for the bt fw file format, and dumped the bt rom with cybt_mem_read, so things are looking up
