Hello, we are using Linux 3.4.68 and the included wl12xx_stio driver with 6.3.5.0.98 firmware on our OMAP3 board.
We are using ConnMan 1.19 and Wpa_Supplicant 2.0 to connect to a WiFi router. The association eventually succeeds and internet connectivity is achieved and maintained, however, we always receive this error:
wl12xx: ERROR command complete timeout
at the beginning of association. The driver then seemingly must reset itself several times:
wl12xx: ERROR watchdog interrupt received! starting recovery
Finally, the association is completed and all is well.
What could cause these issues and how can I fix them? Thanks!
I've pasted the dmesg output and also the output of cat /proc/interrupts below. I appreciate your help.
