Sorry that I overlooked your post earlier (was out during that time and didn't have time to catch up the backlog...)

Your case is different from Luka's, your device do have the id calibrated, just that it is not added to the board-2.bin.

[  124.524661] ath10k_pci 0000:01:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 144d:c14f

Here are some general guidance you might want to find out the right board file if it failed at first place.

For you case, your board is calibrated, so from the failure logs, you coudl see above string - sub 144d:c14f, and then either your install package or you could seek the driver online, e.g this might work to your board.

And then extract the file you could see the PCI\VEN_168C&DEV_003E&SUBSYS_C14F144D&REV_32 is using "eeprom_ar6320_3p0_SS_720.bin", so if you could give it a try by renaming it to board.bin under your firmware folder.

And would be appreciated if you could feedback the result.
