Dear community,

I would like to report that the version: 14.68.36.p204 of
sd8801_uapsta.bin binary (newest, SHA1:
ecdfcf8e2ca15f5682ab94fd30ba29fb869b24a7) has the issue with getting
channel info (HostCmd_CMD_STA_CONFIGURE command execution).

As a result the module seems to be stuck and no transmission is
performed.

The issue is not present in 14.68.36.p146 verson of the firmware.

For reproduction one needs to execute:
#! /bin/sh
set -x
wpa_supplicant -B -i mlan0 -c /etc/wpa_supplicant.conf
sleep 3
dhclient mlan0

exit 0



I'm using the Azurewave AW-NM191NF module (with 88W8801 SoC).

Best regards,

Lukasz Majewski

I'm facing similar problems with i.MX8MN EVK and u-blox wireless SDIO
module with 88W8801 SoC and mwifiex_sdio driver for linux 5.15.28 kernel.
I tried firmware 14.68.36.p204 and 14.68.36.p60. I'm not able to establish
a WPA protected link using wpa_supplicant.

You mentioned that you have tested with 14.68.36.p160 and 14.68.36.p146
firmware versions without having issues in STA mode. Where did you get
these firmware versions?

I was not able to find them neither in linux-firmware, mwifiex-firmware
nor imx-firmware repositories.
