Hi, I am running kernel 6.6.18 on an imx6dl board with the WL18XX Wifi chip. I tried using the most recent firmware (8.9.1.0.2) from the master branch of: https://git.ti.com/cgit/wilink8-wlan/wl18xx_fw/log/ but the following error is seen: wlcore: ERROR Your WiFi FW version (8.9.1.0.2) is invalid. Please use at least FW 8.9.*.*.58. Then I used FW 8.9.0.0.90 and this version is accepted. Should drivers/net/wireless/ti/wlcore/boot.c b be changed to allow running the latest 8.9.1.0.2? What is the recommended wl18xx firmware version when running a mainline kernel? Any suggestions? Thanks, Fabio Estevam
