AX210 with ROM-5721 on DB-5901

Technical Supports
1

Hello,

we try to run an Intel AX210 Wifi module in the M.2 slot. What we did so far:

  • run lspci → missing driver
  • compile iwlwifi and iwlmvm into the kernel → missing firmware
  • put firmware from Intel wireless firmware page to /lib/firmware
  • Tried firmware version 59, 62, and 66 of the microcode files and added the pnvm file from the corresponding release iwlwifi: add new FWs from core63-136 release - kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel
  • Checked for bug reports:
    • recommending adding/removing the pnvm files,
    • checking for kernel compatibility (ucode 59 for kernel 5.10 and ucode 66 for 5.15 as in used VC0056 standard advantech rom 721 yocto-based image) and for only 1 supported PCIe lane (as seems to be the case on the rom-5721),
    • deactivating ASPM which is already the case with ASPM being “Disabled” for the LinkCtl
    • working with kernel modules and rmmod’ing iwlwifi and iwlmvm and adding them again (didn’t try)
    • setting options iwlwifi disable_11ax=Y in modprobe config (didn’t try)
    • use kernel 5.15.107: Re: Intel AX210 - linux issues - Intel Community

Sometimes, an interface wlan0 is created and can be found with iwconfig (without being usable at all), but even after power cycling, starting the hardware fails in most cases:

So the question is whether you might have any clue or hint on what to consider or change, maybe add something in the kernel or configure some DIP switches on the eval board, or is it not possible at all to operate the AX210 on the DB-5901 or with the ROM-5721?

In case of bugs in the 5.15 kernel branch, where will be able to find an updated branch?

TIA!

Issue solved. Antenna was bad or broken.

Using the microcode file ty-a0-gf-a0-59.ucode and the iwlwifi driver, wlan comes up correctly, showing interface wlan0, allowing setting up an AP via hostapd.

Don’t forget building iwlmvm as well.
