Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG) configuration are causing the following errors when UTF firmware is loaded to the target. Error message 1: [ 598.015629] ath10k_pci 0001:01:00.0: failed to ping firmware: -110 [ 598.020828] ath10k_pci 0001:01:00.0: failed to reset rx filter: -110 [ 598.141556] ath10k_pci 0001:01:00.0: failed to start core (testmode): -110 Error message 2: [ 668.615839] ath10k_ahb a000000.wifi: failed to send ext resource cfg command : -95 [ 668.618902] ath10k_ahb a000000.wifi: failed to start core (testmode): -95 Avoiding these configurations while bringing the target in testmode is solving the problem.
