Dear Kalle, I tried the latest firmware available on your github account for IPQ8074 on my Xiaomi AX6 router, and it produces a firmware crash right after the Q6 processor tries to boot: [ 7.503844] ath11k c000000.wifi: ipq8074 hw2.0 [ 7.504147] remoteproc remoteproc0: powering up cd00000.q6v5_wcss [ 7.511424] remoteproc remoteproc0: Booting fw image IPQ8074/q6_fw.mdt, size 668 [ 8.511575] remoteproc remoteproc0: remote processor cd00000.q6v5_wcss is now up [ 8.517199] kmodloader: done loading kernel modules from /etc/modules.d/* [ 8.555705] ath11k c000000.wifi: qmi ignore invalid mem req type 3 [ 8.563181] ath11k c000000.wifi: chip_id 0x0 chip_family 0x0 board_id 0xff soc_id 0xffffffff [ 8.563231] ath11k c000000.wifi: fw_version 0x270204a5 fw_build_timestamp 2022-08-04 13:05 fw_build_id WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 ...................................

Firmware 2.5.0.1-01208 is the last one that works properly. There are others who also experience the same firmware crash with the same device. Can you please help us with this? Regards, Csaba
