I know that the patch submitted here is in a broken state. But was there any decision made what will be done about this problem in general? This will become a problem again on IPQ4019 when somebody must patch the mac address in the pre-cal data. The OTP firmware binary of ath10k will simply reject its content when the checksum in the pre-cal data is incorrect. This reject will happen when the PARAM_FLASH_SECTION_ALL parameter is sent to the OTP [1] (step 4). Instead it will then use the boarddata from board-2.bin which was send to the device in step 3. It is then missing most calibration data which is specific to this single board. Kind regards, Sven [1] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3d9195ea19e4854d7daa11688b01905e244aead9
