Do you know what would be the reason for this?

Hi Pavan,

Please allow me until tomorrow EOD to discuss this internally.

Best,
Corinne

Hi Corinne,
Thank you for support.

I have found Ti community page which is similar to the issue which I am facing e2e.ti.com/.../wl1837mod-wifi-wlcore-driver-crash-during-rekeying

In that page someone suggest about these patches https://github.com/astrand/wilink8-wlan-build-utilites/tree/r8.8/patches/kernel_patches/5.4

Are these patches helpful for the issue which I am facing?

Thanks!!

Hi Corinne,

I have found one more  Ti community Page   https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/976244/wl1837mod-wl1837mod-wlcore-error-firmware-boot-failed-despite-3-retries

There it seems like After disabling ELP the issue seems to be resolved.

on our device - power save is on

iw dev wlan0 get power_save
Power save: on

So by disabling ELP will it solve the above issue?

Hey Pavan,

Are you still using kernel 5.10? If that is the case then some steps would have to be taken independently of the patches we provide to get WL1837 working with that kernel due to TI not supporting beyond kernel 4.19. The steps in the first E2E you attached are worth trying, however please note that those are for kernel 5.4 which is still beyond the version that TI supports and the git repository that was attached is not affiliated with TI.
