iwlwifi Microcode error on Raspberry Pi 5 with AX210

[toddeu1]

Waveshare hat (image of AX210 attached) on stock RPi 5.  

uname -a: Linux raspberrypi 6.12.25+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.25-1+rpt1 (2025-04-30) aarch64 GNU/Linux

dmsg output attached (error in dmsg output).  Relevant portion:

I have tried all the drivers that will load in /lib/firmware ( iwlwifi-ty-a0-gf-a0-8*.ucode) from raspi-firmware.  All produce the same error.

Everything seems correct - verified process with a number of other sites (example: https://www.jeffgeerling.com/blog/2025/exploring-wifi-7-2-gbps-on-raspberry-pi-5) and (https://www.waveshare.com/wiki/PCIE_TO_M.2_E_KEY_HAT+).  Though the Geerling site uses -c0- drivers vs. -a0- however my AX210 is looking for -a0-.

No other obvious problems or errors.

Any help would be appreciated...

Hello toddeu1,

Thank you for posting in the Intel Communities.

To better understand the issue and offer an effective recommendation, please provide the following key information:

1. Is this the exact system you are using? Link to Waveshare Raspberry Pi HATs
2. If yes, is the AX210 wireless component an add-on?
3. Please share your system configuration by following this User Guide and attach the log file (.txt) when you reply to this post.

I look forward to hearing from you soon.

Best regards,

JeanetteC.

JeanetteC -

1. https://a.co/d/jcbqcXU <- exact waveshare unit.
2. I believe this Waveshare board is specifically designed for this type of card (AX210) though not necessarily this exact card.

3. There is no link to the user guide in your message?  Are you looking for dmesg output or can you please send the linik?

Thanks

Todd

Attached is the dmesg output for a clean boot - if that's not what you need please let me know....

Hello toddeu1,

Please be informed that I am still investigating this issue internally and require additional information to understand why the microcode isn't functioning with your setup. Could you please provide the output of the following commands:

1. # lspci​ 
2. # modinfo iwlwifi​ 
3. # lsmod | grep iwlwifi​     
4. lsmod | grep wmi
5. dmesg > dmesg.log
6. ethtool -i wlan0 | grep firmware

I look forward to your response.

Best regards

FIles attached named for each command.

lsmod | grep wmi produces no output so no file.

Hello toddeu1,

Thank you for the update. I understand that the RPi 5 doesn't support kernel 6.15 yet, making testing impossible at this time. It's advisable to contact RPi support directly for guidance on the issue.

I will close this thread now. If you need assistance in the future, please submit a new inquiry, as this thread will no longer be monitored.

Sincerely,

JeanetteC.
