Hi All,

We are using 43455 chip on imx7 and we are seeing the below errors. We are running brcmfmac Mothra release.

Has anyone else encountered this issue? is there a patch available for this from Cypress?

Please check with my drivers and see if the error is happening for you.

Driver compiled for armv7.

Check

>>readelf -h

Hi anavalgund_2097886

Could you provide the steps/sequence of commands that you have send to bringup the driver. Have you followed the steps give in the following README.

Hi vnak

Sorry I did not clarify. The issue is not seen when we load the driver. The driver loading is successful and there are no issues there.

We are following the exact steps in the the Readme.

The sdio issues are seen after the radio has been running for a while, doing suspend/resumes and passing traffic.

Thanks and regards,

Aparna

Sorry for the wait.

Please provide the steps while going into suspend/resume so that i could reproduce the issue.

I am trying with the following setup commands:

>>iperf3 -s &

>> i=0;while [ 1 ];do echo +2 > /sys/class/rtc/rtc0/wakealarm;echo mem > /sys/power/state ;sleep 10;i=`expr $i + 1`;echo "========suspend $i times======="; done

Regards,

Vinayak

Hi vnak,

Thanks for getting back to me. We are using wpa_supplicant and wowl is enabled. "wl wowl 1"

so the functions brcmf_cfg80211_suspend and brcmf_cfg80211_resume are getting called during suspend and resume. I am connected to an AP (wpa2-psk) and i use the following command for suspend:

while true; do rtcwake -d /dev/rtc0 -m mem -s 7; sleep 2; done

thanks and regards,

Aparna

Hi vnak,

I enabled the radio driver debug for SDIO and I have attached the same here. Does this tell us anything?

Any ideas on how to debug this issue at our end?
