QCA9880/9890 rfkill

[William Riba]

Hi Adrian - thank you for the quick response. I assume you're referring the otp.bin firmware file? Is there a mapping of the OTP to EEPROM settings available? That would be an easy fix if I can make a modification there to activate RFKILL.

Hi,

The GPIO line needs to be hooked in via the relevant EEPROM/OTP setting so the firmware programs things in correctly.

Go dump the OTP and see what the rfkill firmware line is.
