I have tried to make a new board-2.bin with boardData_2_0_QCA9888_5G_Y9484.bin and boardData_1_0_IPQ4019_DK04_5G.bin.
dmesg part form Stock:
ol_transfer_bin_file: Board Data File download to address=0xc0000 file name=QCA9888/hw.2/boardData_2_0_QCA9888_5G_Y9484.bin
ol_transfer_bin_file: Board Data File download to address=0xc0000 file name=IPQ4019/hw.1/boardData_1_0_IPQ4019_DK04_5G.bin
dmesg part from OpenWRT:
[ 13.423837] ath10k_pci 0000:01:00.0: board_file api 2 bmi_id 0:17 crc32 d94b5d72
[ 18.474359] ath10k_ahb a800000.wifi: board_file api 2 bmi_id 0:21 crc32 e2dfaa91
I overwrite
bus=pci,bmi-chip-id=0,bmi-board-id=17.bin
with
boardData_2_0_QCA9888_5G_Y9484.bin
and rebuild board-2.bin with bdencoder for QCA9888. Replaced board-2.bin in /lib/firmware/ath10k/qca9888 with the new one.
I can’t see no real difference in signal strength.
For IPQ4019
bus=ahb,bmi-chip-id=0,bmi-board-id=21,variant=ASUS-MAP-AC2200.bin
has the same crc32 as
boardData_1_0_IPQ4019_DK04_5G.bin
Tried creating a new firmware-5.bin with the data from stock firmware.
./ath10k-fwencoder -c --otp otp.bin --firmware athwlan.bin --firmware-codeswap=athwlan.codeswap.bin --set-fw-api 5 --set-wmi-op-version 10.4 --set-htt-op-version 10.4
Did not change the signal strength.
I have read Optimized build for IPQ40xx devices but can't find any clue.
Did I do something wrong?
Could it be that the external PA is not activated? RFPA5542 should add around 20dBm.
