Driver breaks on apt update of RPI CM4 6.1.21-v7l+

[remcolouter]

I am currently testing with "AHPI7292S" from Alfa Networks. I have used their prebuilt image and it works as long as there is no apt update/upgrade, only with this particular image I could make it work. With the latest apt upgrade it breaks the driver, since it switches to 64-bit. In the /boot/config.txt, I have added "arm_64bit=0" and it boots again the 32-bit version. I am now at 6.1.21-v7l+ but unfortunately it does not work anymore. I have also tried to rebuild the driver within the new kernel, there were no error messages, but unfortunately it never worked again. When I apply the start.py script, I get:

insmod: ERROR: could not insert module /home/pi/nrc_pkg/sw/driver/nrc.ko: Unknown symbol in module
wlan0: ERROR while getting interface flags: No such device
rmmod: ERROR: Module nrc is not currently loaded

I tried to build the driver on the 64-bit kernel as well, it did the build successfully, but alas the same error message.

Is there anything I can do to make it work with the latest kernel?

Dear @remcolouter,

Please reach out to Alfa Networks for assistance.
However, the issue may stem from the improper use of an incorrect DTS file.
Please check yours by refering to section 3.4 of https://github.com/newracom/nrc7292_sw_pkg/blob/master/package/doc/UG-7292-018-Raspberry_Pi_setup.pdf and https://github.com/newracom/nrc7292_sw_pkg/blob/master/dts/newracom_for_5.16_or_later.dts.

Regards,
Newracom

Thanks for the reply. Will do.

I did see the item about creating this overlay for kernels 5.16+ and did it like this. Unfortunately that did not work either, however I have tried many things, so possibly I did some things in the wrong order. If I have a solution, I will revert to this issue.

Kind regards,

Remco

Just use the install instructions from this repo on a fresh debian bullseye release, but change out the board data file with the one linked in previous issues by newracom (it is easy to find).
