Hello Justin and Kalle, Justin thank you very much for the reply, sorry it took me so long to get back to you but I wanted to do more testing based on your recommendations before I wrote. I tried numerous versions of the firmware-6.bin file from the linux-firmware git, and the repo you linked. I have been hitting the same issue with nearly every version of firmware I try. I included the output from WLAN.RM.4.4.1-00140-QCARMSWPZ-1, but the exact same applies to WLAN.RMH.4.4.1-00042. Under normal circumstances I would try to bisect this, but I can't because I don't have a "good" (working) version of the firmware. I'm doing this on behalf of one of our clients Rick Winscot, I added him to this thread so he can offer his insight. Here's the output from my testing with WLAN.RM.4.4.1-00140-QCARMSWPZ-1: root@bionic-newport:~# ls /sys/class/net/ can0 eth0 eth1 lo root@bionic-newport:~# dmesg |grep ath10k [ 0.000000] Kernel command line: cma=64M coherent_pool=16M net.ifnames=0 ath10k_core.rawmode=1 root=/dev/mmcblk0p2 rw rootwait console=ttyAMA0,115200n8 earlycon=pl011,0x87e028000000 [ 12.356854] ath10k_pci 0001:58:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0 [ 12.762070] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/pre-cal-pci-0001:58:00.0.bin failed with error -2 [ 12.762132] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/cal-pci-0001:58:00.0.bin failed with error -2 [ 12.779272] ath10k_pci 0001:58:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 168c:3363 [ 12.779280] ath10k_pci 0001:58:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 0 testmode 0 [ 12.780635] ath10k_pci 0001:58:00.0: firmware ver WLAN.RM.4.4.1-00140-QCARMSWPZ-1 api 6 features wowlan,ignore-otp,mfp crc32 29eb8ca1 [ 12.858884] ath10k_pci 0001:58:00.0: board_file api 2 bmi_id N/A crc32 4ac0889b [ 12.858894] ath10k_pci 0001:58:00.0: rawmode = 1 requires support from firmware [ 12.866282] ath10k_pci 0001:58:00.0: fatal problem with firmware features: -22 [ 12.873670] ath10k_pci 0001:58:00.0: could not probe fw (-22) root@bionic-newport:~# ls /sys/class/net/ can0 eth0 eth1 lo wlan0 root@bionic-newport:~# dmesg |grep ath10k [ 11.981606] ath10k_pci 0001:58:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0 [ 12.310158] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/pre-cal-pci-0001:58:00.0.bin failed with error -2 [ 12.310206] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/cal-pci-0001:58:00.0.bin failed with error -2 [ 12.349306] ath10k_pci 0001:58:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 168c:3363 [ 12.349314] ath10k_pci 0001:58:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 0 testmode 0 [ 12.350682] ath10k_pci 0001:58:00.0: firmware ver WLAN.RM.4.4.1-00140-QCARMSWPZ-1 api 6 features wowlan,ignore-otp,mfp crc32 29eb8ca1 [ 12.432281] ath10k_pci 0001:58:00.0: board_file api 2 bmi_id N/A crc32 4ac0889b [ 12.978328] ath10k_pci 0001:58:00.0: Unknown eventid: 3 [ 12.994313] ath10k_pci 0001:58:00.0: Unknown eventid: 118809 [ 12.997236] ath10k_pci 0001:58:00.0: Unknown eventid: 90118 [ 12.997886] ath10k_pci 0001:58:00.0: htt-ver 3.60 wmi-op 4 htt-op 3 cal otp max-sta 32 raw 0 hwcrypto 1 root@bionic-newport:~# iw phy phy0 interface add mesh0 type mp root@bionic-newport:~# iw mesh0 info Interface mesh0 ifindex 6 wdev 0x2 addr 94:92:d2:00:04:04 type mesh point wiphy 0 txpower 0.00 dBm root@bionic-newport:~# iw dev mesh0 set freq 5745 80 5775 root@bionic-newport:~# ifconfig mesh0 192.168.1.10 SIOCSIFFLAGS: Invalid argument root@bionic-newport:~# dmesg |grep ath10k [ 11.981606] ath10k_pci 0001:58:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0 [ 12.310158] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/pre-cal-pci-0001:58:00.0.bin failed with error -2 [ 12.310206] ath10k_pci 0001:58:00.0: Direct firmware load for ath10k/cal-pci-0001:58:00.0.bin failed with error -2 [ 12.349306] ath10k_pci 0001:58:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 168c:3363 [ 12.349314] ath10k_pci 0001:58:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 0 testmode 0 [ 12.350682] ath10k_pci 0001:58:00.0: firmware ver WLAN.RM.4.4.1-00140-QCARMSWPZ-1 api 6 features wowlan,ignore-otp,mfp crc32 29eb8ca1 [ 12.432281] ath10k_pci 0001:58:00.0: board_file api 2 bmi_id N/A crc32 4ac0889b [ 12.978328] ath10k_pci 0001:58:00.0: Unknown eventid: 3 [ 12.994313] ath10k_pci 0001:58:00.0: Unknown eventid: 118809 [ 12.997236] ath10k_pci 0001:58:00.0: Unknown eventid: 90118 [ 12.997886] ath10k_pci 0001:58:00.0: htt-ver 3.60 wmi-op 4 htt-op 3 cal otp max-sta 32 raw 0 hwcrypto 1 [ 256.819171] ath10k_pci 0001:58:00.0: Unknown eventid: 3 [ 256.834413] ath10k_pci 0001:58:00.0: Unknown eventid: 118809 [ 256.837352] ath10k_pci 0001:58:00.0: Unknown eventid: 90118 [ 256.884876] ath10k_pci 0001:58:00.0: must load driver with rawmode=1 to add mesh interfaces Mahalo, Cale Collins
