Does anyone know how to use a PCIe GPRS-3G modem on iMX6 board?

[giorgiosoldavin]

Hi all,

     I'm working on an Android AOSP 4.0.4; I've currently plugged a PCIe modem on board and added a SIM card; modem is 5350 SIMCom, but I can't let it work. My impression is that is not recognized at all by kernel. Because I haven't a specific modem driver for Android, I followed instructions for Linux drivers and defined a custom RIL. It seems that the modem is not recognized at all, but first question: PCIe modem should be linked to a ttyUSB? Are there any options to be changed for building an AOSP that recognize the modem?

Thank you for your support!

Hi Giorgio

what is interface of that card, if usb then one can look at below link

Google Groups

also modem firmware may be changed from time to time and it may be recommended

to check for driver suitable for particular radio chip revision. They may differ from

one radio chip batch to other. And it should be provided by the vendor.

Best regards

One can check if card is detected by system (lspci),

PCIe levels may be tweaked, this is described in Table 2-1. IOMUXC GPR8
