3G modem on imx6 platform

[javierw]

Hello.

We have tried to add the 3G modem to our board, but failed.

Our board detail is as below:
Hardware:  imx6dq
OS:        Android 4.2.2 sabresd
3G modem:  Huawei MU609
3G modem interface: Mini PCIe

Is there any proposal on the design with 3G modem? 
What 3G module the Freescale Android 4.2.2 BSP has supported successfully?

Thank you and hope that we can get some help from you.

Hi Javier

please look at p.3 attached Release Notes,

EM770W was tested,  however firmware may

be changed from time to time. So it may be recommended to check for

driver suitable for particular radio chip revision.

For ZTE FM210 modem there is a common option usb driver .
