WL1837MOD: Linux: Why do the new wl18xx-fw-4.bin not work?

Hi evrybody

I built the WL18xx drivers by next steps:
lyudmila@lyudmila-linuxmint ~/wl8-build_Point9-6 $ git clone git://git.ti.com/wilink8-wlan/build-utilites.git
lyudmila@lyudmila-linuxmint ~/wl8-build_Point9-6 $ cd build-utilites
lyudmila@lyudmila-linuxmint ~/wl8-build_Point9-6/build-utilites $ ./build_wl18xx.sh init
lyudmila@lyudmila-linuxmint ~/wl8-build_Point9-6/build-utilites $ ./sudo_build_wl18xx.sh update R8.7_SP3

The building completed successfully, but wi-fi do not work.

About 2 years ago I built the WL18xx drivers by the same way and wi-fi worked.

I replaced the new wl18xx-fw-4.bin with the old wl18xx-fw-4.bin and wi-fi began to work.

They have different sizes:
old wl18xx-fw-4.bin - 746,2 kB
new wl18xx-fw-4.bin - 714,0 kB

Why do the new wl18xx-fw-4.bin not work?
Maybe do replace git:// with https:// somewhere else in the configuration.sh script or generally everywhere?

Sincerely

Hello,

I don't understand why the new FW wouldn't work. Could you share an error log or dmesg output?

Hi,

Latest version of WiLink8 driver is required for firmware version 8.9.1.0.0 . Please checkout following links:

https://git.ti.com/cgit/wilink8-wlan/wl18xx_fw/commit/

https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1168002/faq-wl1837mod-new-wilink-firmware-v8-9-1-0-0-and-driver-release-available-11-3-2022

Since you are running R8.7_SP3 , you may use firmware version 8.9.0.0.88 : https://git.ti.com/cgit/wilink8-wlan/wl18xx_fw/commit/?id=bda5304cc86e9c4029f8101394d2a8b39c640f53

In case you would like to use the latest firmware , you would need to update WiLink8 driver and 18xx-ti-utils.git

Thanks
