I just realized that the functionality of board-2.bin in ath10k driver was commented out by someone of my company, and now I restored this functionality in ath10k driver. But, firmware is still crashed, and it seems like it is caused by failing to fetch board data. That is said, the driver failed to find a matched (bus=pci,bmi-chip-id=0,bmi-board-id=11) board data from board-2.bin. Does that mean the vendor of this wireless module has not committed their board data to upstream and build to board-2.bin file?
