This is the wrong way to do it. You're using your card without correct calibration data. No wonder it crashes. I bet you have a 00:03:07:12:34:56 mac address on your ath10k wlan interface. You need to extract board.bin from NAND flash of the router you have. OpenWRT does this automatically for some devices (e.g. TP-Link Archer C5/C7) as far as I know. You should either allow OpenWRT to extract the file itself (probably deleting the existing board.bin and rebooting the system) or look at script responsible for that and do it yourself. >>> [791505.910000] ath10k_pci 0000:01:00.0: qca988x hw2.0 (0x4100016c, >>> 0x043202ff) fw 10.1.467.2-1 api 4 htt 2.1 wmi 2 cal otp max_sta 128 >>> [791505.920000] ath10k_pci 0000:01:00.0: debug 0 debugfs 1 tracing 0 >>> dfs 1 testmode 1 >>> [791506.030000] ath: EEPROM regdomain: 0x0 >>> [791506.030000] ath: EEPROM indicates default country code should be used >>> [791506.030000] ath: doing EEPROM country->regdmn map search >>> [791506.030000] ath: country maps to regdmn code: 0x3a >>> [791506.030000] ath: Country alpha2 being used: US >>> [791506.030000] ath: Regpair used: 0x3a >>> [791551.530000] ath10k_pci 0000:01:00.0: otp stream is empty, using >>> board.bin contents >>> [791718.130000] device wlan1 entered promiscuous mode >>> [791718.340000] ath10k_pci 0000:01:00.0: firmware crashed!

Before you start getting traces or testing 10.2 firmware make sure you fix your board.bin first, please. Michał
