hi there,
I am porting WWD to a custom board powered by a Cortex-A9 and Murata SN8000x module (based on BCM43362A2) using SDIO interface.
A lot of thing are now working (enumeration, FW download, WAN scan, open AP join) until I try to join a WPA/WPA2 protected AP.
Digging into WWD showed me that the ioctl sending the WPA key (WLC_SET_WSEC_PMK) never gives any answer. That leads wifi_prepare_join to fail and propagates the error until my initial call to wwd_wifi_join.
My example only calls a very few wwd functions:
* wwd_management_init
* wwd_wifi_get_mac_address
* wwd_wifi_get_wifi_version
* wwd_wifi_join
I am wondering what can cause WLC_SET_WSEC_PMK ioctl not to answer.
Wrong firmware ? (the same FW runs perfectly on Murata's SN8000X EVK)
Wrong DCT ?
Timing issue during init ?
Any suggestions or guidance to debug will be appreciated. Thanks.

Hi folks,
I have some news about the issue, unfortunately I do not consider it is 100% solved.
I reproduced the issue on proven hardware (namely Murata SN8000x EVK). I wrote a custom application largely inspired from NoOS_Canned_send example.
The initialization is the same trivial sequence:
* wwd_management_init
* wwd_wifi_get_mac_address
* wwd_wifi_get_wifi_version
* wwd_wifi_join
And is works !!
But when I insert a scan before join (very useful to find spots), joining only works on OPEN AP. Try to join a WPA/WPA2 protected AP fails because of WLC_SET_WSEC_PMK ioctl that never answer.
Is there some cleaning stuff to perform after scanning and before joining ?
Thx for helping me.
