Murata SN8000/imx6ul Board can not connect to network

Hello all. 

 

Sorry, I'm new to this so please bear with me.  I am trying to bring up an SN8000 on a custom i.MX Linux board based on the imx6ul EVK design. I am able to partially bring up the module, scan for (and detect) networks using iw as well as wpa_cli but I can not connect to open or secured networks. Has anyone had experience with the i.mx 6 and SN8000 that can give me advice on bringing up the SN8000 as well as how to better diagnose these connection issues?

 

Below are examples of boot messages and connection error messages and I have also attached a full trace from the driver using dhd_msg_level=0x2fff

 

Thanks.
