Problem with AX200 wi-fi module

stevan_marinkovic — Thu, 09 Sep 2021 08:58:40 GMT

Dear Community,

We are using your Wi-Fi 6 AX200 wi-fi module in order to proof our development concept and planning to build it into final solution.
But we have the following problem:

- We are using ARM processor in Xilinx Zynq UltraScale+ FPGA and running Linux Kernel 5.4 on it.
- Firmware file that we are using is iwlwifi-cc-a0-46.ucode (also tried FWs 48 and 50 without success)
- These are the additional configs that we enabled in our Kernel:
CONFIG_FW_LOADER=y
CONFIG_PCI_MSI=y
CONFIG_EXTRA_FIRMWARE="iwlwifi-cc-a0-46.ucode"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
CONFIG_IWLWIFI=y
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLDVM=y
CONFIG_IWLMVM=y

- After executing iw dev command from Kernel command line, we have the following:
phy#0
Interface wlan0
ifindex 4
wdev 0x1
addr 6c:94:66:a2:04:ae
type managed
txpower 0.00 dBm
multicast TXQ:
qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets
0 0 0 0 0 0 0 0 0

- Then after "ip link show wlan0":
4: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 6c:94:66:a2:04:ae brd ff:ff:ff:ff:ff:ff

- But when we try to set the link up (ip link set wlan0 up), we have the following errors (complete dmesg is below):

RTNETLINK answers: Input/output error

I saw a lot of similar issues on different forums (but with different Linux Kernels), tried all of suggested workarounds, but without success.
Could you please suggest me proper solution for upper explained problem?

Thanks a lot,

Stevan

This is an old thread but I'm having this same issue and would like to know if there was a final solution identified? I haven't been able to find one thus far.
