wlcore on 4.19.94-ti-r73 #1buster crashing BBGW Wifi.

I am running a BeagleBone Green Gateway as a … gateway, transferring wifi to ethernet. From time to time the Wifi seems to freeze, and the connection is dead. In dmesg I find these messages:

It seems that there is something not right.

Any Idee?

You can try a different firmware.
Personally I found that Rev. 8.9.0.0.88 was unstable for my use case and switched to 8.9.0.0.86.
TI has since updated the firmware to Rev 8.9.0.0.90, but I did not tested that version.
You can download wl18xx firmware from wilink8-wlan/wl18xx_fw - WiLink8 WLAN development project..
A firmware changelog is available at changelog - wilink8-wlan/wl18xx_fw - WiLink8 WLAN development project.

Thx, it seems that 8.9.0.0.86 has some security flaws, hence 8.9.0.0.88. I’d like to try 8.9.0.0.90, but the documentation mentions that every version > 8.9.0.0.88 should run a script, see https://git.ti.com/cgit/wilink8-wlan/wl18xx_fw/tree/changelog:

======

Rev 8.9.0.0.89
		- Integrated 105C temp support for WiLink8 COB designs
		( IMPORTANT : All WiLink8 based designs (modules or COB) using this firmware version or later, need to re-run
		configure-device.sh script using updated INI files. Please update repository https://git.ti.com/git/wilink8-wlan/18xx-ti-utils.git )

======

I am not sure how to proceed to do that. RobertCNelson, can you give any clues?
