We are using customized board based on SC20 with Android 7.1.2.

Now facing some issue with wcnss driver something went in previously was fine.

1. Missing/issue part now
   <>>> No wcnss_wlan triggered by userspace

2. Also notice Module signature verification failure when clicking WIFI logo
   <>>> Request for unknown module key ‘Magrathea: Glacier signing key: e4cf47b3f89be79091451ac15614216e676b4bcd’ err -11

I notice issue when fastboot flash command failed due size of system.img (now 986368980).

Appreciate your feedback.

Thanks & regards,
Zahir

Hi Zahir,
Can you find wlan.ko in SC20? You should fastboot boot.img and system.img simultaneously.

[Praween_Kumar]

Hi,

Facing same issue in one of my unit, which is custom based on SC20W using 7.1.2.
@Rooney Yes I am able to find wlan.ko in out/target/…/system/lib/wlan.ko which eventually calling pronto_wlan.ko.

However, my unit is not able to boot complete and watchDog report issue as wcnss crash!!!

Hi Zahir,
i found wlan.ko file /system/lib/modules directory. But i have the same issue

[jax.zhang]

Dear customer:
Does any one can try to flash all the android images?
On android7, we store the wlan.ko in system image.
So when we flash the boot only, the signature will casue the wlan.ko can’t be installed in the kernel.
