IMX8QM BOARD: WIFI disconnet in reboot

[vinothkumars]

Hi All,

I am working on IMX8QM Custom platform with YOCTO Linux - L5.10.

8987 WIFI BT CHIPSET,

WIFI connection is working fully power off and power on the board not in every reboot of the one custom board

 
In reboot scenario while connect to the wifi got following response and sdio cmd timeout error,
            ieee80211 phy0: sched_scan start : n_ssids=1 n_match_sets=1
            ieee80211 phy0: n_channels=41 interval=10 ie_len=143
            ieee80211 phy0: sched scan stop!
            mwifiex_sdio mmc1:0001:1: info: trying to associate to 'SLS-WiFi' bssid ec:bd:1d:c3:90:b0
            mwifiex_sdio mmc1:0001:1: ASSOC_RESP: failed,    status code=17 err=0x21 a_id=0x0
            mwifiex_sdio mmc1:0001:1: assoc failure: reason Unknown connect failure 
            mwifiex_sdio mmc1:0001:1: info: association to bssid ec:bd:1d:c3:90:b0 failed

Will you please give some ideas about this.

Hi Vinothkumar

>WIFI connection is working fully power off and power on the board not in every reboot of the one custom board

one can try to increase time between "off" and "on" to allow all power supplies be fully discharged.

Best regards

Thank you @igorpadykov for the quick reply,

I able to connect with router any time even power off and reboot. But, while I connect with mobile I got this issues, able to connect with power off and power on not in reboot.
