Problems with new PCIe module

[Josep Pijuan]

Hello,

We are working in the Isoblue setup to adapt it to using a different PCie module for GNNS and LTE based on Quectel manufacturer. The other hardware modules are the same, Ixora carrier voard (v1.1a) and Apalis imx6 (v1.1c).

Given a basic Isoblue build, what configuration/files should we change (before building the image) in order to use the different GNSS module?

At the moment we have created a patch to add the drivers for the PCIe module. Using mmcli command we are able to get gps positions, however we are not able to log the gps positions with kafka.

Do you recommend to use branch 2.7 or master?

Best regards

Josep

Hello Josep,

We are working in the Isoblue setup to adapt it to using a different PCie module for GNNS and LTE based on Quectel manufacturer. The other hardware modules are the same, Ixora carrier voard (v1.1a) and Apalis imx6 (v1.1c).

That sounds great!

As far as I know, if you want to include this module, you will need to include the corresponding kernel driver for your module in the kernel config before building the image.

This is the location of the defconfig file that the build process uses to build the kernel: https://github.com/ISOBlue/meta-toradex-nxp/tree/v2.7/recipes-kernel/linux/linux-toradex-4.1-2.0.x/apalis-imx6

Since you are currently able to use mmcli to get gps positions from your module, I would assume that the patch you created is for defconfig then?

however we are not able to log the gps positions with kafka. 

We are using gpsd to fetch the position from our gps module and then send the message to Kafka. If you want to log your module's gps data, you need have a middleware to query the gps position.

Do you recommend to use branch 2.7 or master?

Yes. Branch v2.7 is the stable branch.
