Hello friends,

We are using TI AM3351 processor with WiFi/BT module BCM43455 over SDIO interface.

TI SDK : ti-processor-sdk-linux-am335x-evm-04.01.00.06

Linux Kernel is 4.9.41-ge3a80a1c5c

Wlan driver is brcmfmac :

brcmfmac: F1 signature read @0x18000000=0x15264345

Firmware version = wl0: Mar  1 2015 07:29:38 version 7.45.18 (r538002) FWID 01-6a2c8ad4)

When device is connected using wpa_supplicant, to a AP of 5GHz, it is getting disconnected repeatedly after every reconnection with the 5GHz AP.

Attached log I'm seeing when wpa_supplicant is run in debug mode: log.txt

As I can see in the log, an event NL80211_CMD_DISCONNECT is received, I suspect this event is causing this issue.

But strangely this issue is not observed with the 2.5GHz WiFi APs, Working fine with 2.5GHz APs.

Can you guys help me resolving this issue.

Help is much appreciated.

Thanks,

aniket jesu

Hi,

Could you post the wpa_cli commands that you followed for connecting with the 5G AP before disconnect occurs.

Looking at the firmware, it is dated back to 2015. Can you please repeat your test with the latest FMAC driver and firmware release https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Cypress-Linux-WiFi-Driver-Release-FMAC-2... If the failure is still observed, please attach the complete supplicant logs containing the NL80211_CMD_DISCONNECT call.
