Forum Post: RE: Wi-Fi: BlueGiga WF111 SDIO Driver for AM335x Problem

Hi Rafael

I saw WF111 SDIO clock uses various frequencies, usually it runs slowly but sometimes it sets a higher frequency. My board worked fine @2MHz but it had SDIO errors when using higher frequency. Maybe your board has the same issues?. I modified omap_hsmmc driver to limit max frequency and it seems to work fine.

Now I have a new hardware and WF111 runs OK @50MHz in AP mode, but I'm having problems with STA mode:

root@am335x-evm:~# iwconfig wlan0 essid 'My Wi-Fi' key myweppassword [ 475.597290] unifi1: unifi_siwessid: Join failed, status -5 Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Input/output error. 

Note: I'm using driver version 5.2.2

Regards
