3G Issue on imx6q

blurencetin — Tue, 02 Sep 2014 07:45:10 GMT

Hi all,

We are porting Huawei MU509 3G Module to our 6q board on Android JB 4.3

After we add power-on time sequence and set "Wakein" to high, the module works well, ttyUSB devices could be detected and baseband version is correct.

But, when we plugin sim-card, baseband version shows "unknown", network/signal strength/mobile network type are incorrect.

We checked the log, seems MU509 goes to “selective suspend” , then resume, and changing the state endlessly.

Anyone meet such issue? any suggestion for it?

Here's the log and huawei option.c
