board-sdio.bin is nothing but the board.bin variant used by SDIO 
modules. Check with the board/module vendor for the board.bin. This is 
one possible cause for the firmware assert.

You also need to get the firmware-x.bin for QCA6174 SDIO module. I do 
not think that the PCIe firmware of QCA6174 or the SDIO firmware of 
QCA9377 would be compatible with this. If you do not have one, probably 
this information from Erik 
(https://github.com/erstrom/linux-ath/wiki/Firmware) would be of some 
help.
