I found that QCA9887 does not have firmware supporting adaptive-cca functionality. The log information of the firmware is as follows: ___ [ 33.181470] ath10k_pci 0000:00:00.0: qca9887 hw1.0 target 0x4100016d chip_id 0x004000ff sub 0000:0000 [ 33.191040] ath10k_pci 0000:00:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 1 testmode 1 [ 33.203814] ath10k_pci 0000:00:00.0: firmware ver 10.2.4-1.0-00033 api 5 features no-p2p,ignore-otp,skip-clock-init,mfp,allows-mesh-bcast crc32 c232a0c3 [ 33.282624] ath10k_pci 0000:00:00.0: Direct firmware load for ath10k/QCA9887/hw1.0/board-2.bin failed with error -2 [ 33.293441] ath10k_pci 0000:00:00.0: Falling back to user helper [ 33.467321] firmware ath10k!QCA9887!hw1.0!board-2.bin: firmware_loading_store: map pages failed [ 33.487054] ath10k_pci 0000:00:00.0: board_file api 1 bmi_id N/A crc32 546cca0d [ 34.582873] ath10k_pci 0000:00:00.0: htt-ver 2.1 wmi-op 5 htt-op 2 cal file max-sta 128 raw 0 hwcrypto 1 [ 34.718163] ath: EEPROM regdomain: 0x0 [ 34.718169] ath: EEPROM indicates default country code should be used [ 34.718172] ath: doing EEPROM country->regdmn map search [ 34.718183] ath: country maps to regdmn code: 0x3a [ 34.718187] ath: Country alpha2 being used: US [ 34.718190] ath: Regpair used: 0x3a __ Is there any firmware supporting adaptive-cca function?
