Waveshare SIM7600G on Jetson board

Hi

I’m investigating Waveshare SIM7600G-H support for Jetson Nano. As far as I can see there are two options:

Option 1. install the wwan driver for the SIMCOM 7600G on Balena-Jetson yocto build. ModemManager clearly gives issue that there is no wwan.
Option 2. Enable RNDIS on simcom board AT+CUSBPIDSWITCH=9011,1,1 and enable RNDIS support in meta-tegra(?)

I’ve found this on nvidia forum: How to enable TX2 USB RNDIS function - Jetson TX2 - NVIDIA Developer Forums

I’ve opened issue on github repo:

Option 2

    us 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/5p, 480M
        |__ Port 2: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
            |__ Port 1: Dev 3, If 0, Class=Vendor Specific Class, Driver=rt2800usb, 480M

            |__ Port 3: Dev 4, If 1, Class=CDC Data, Driver=rndis_host, 480M

            |__ Port 3: Dev 4, If 4, Class=Vendor Specific Class, Driver=, 480M

            |__ Port 3: Dev 4, If 5, Class=Vendor Specific Class, Driver=, 480M

lsusb -t shows rndis_host. I don’t know why modemmanager doesn’t init

Hi, did you try to make the modem work with the Nvidia reference images first?

Hi Martjin, if you can get this modem working with the regular Jetpack distribution, then we can grab some information from that OS such as ModemManager and kernel version, plus drivers, and see if we can get them added to balenaOS. Let us know if you get it working on Jetpack.

Hi,

Thanks for the answer. I will see what I can do to make it work on the image supplied by Nvidia.

As far as I can see, qmi_wwan or simcom_wwan driver is missing. I’m currently using only qmi_wwan drivers sucessfully on SIMCOM7600E-H for like a year.

I found a forum post with similar issues regarding Kernel 4.9.201-terga nstall-ec25-qmi-wwan-driver-in-kernel-4-9-201-terga/8686

installed with:
apt install modemmanager libqmi-utils

This is what ubuntu 18 modemmanger gives me back.

I’ve tried different kind of PID configurations without any luck:

AT+CUSBPIDSWITCH=9001,1,1

This command support pids, 9001 is the default value.

PID configuration:

9000:Diag, NMEA, At, Modem, Audio, Rmnet nope

9001:Diag, NMEA, At, Modem, Audio, Rmnet default

9002:Diag, NMEA, At, Modem, Audio, Rmnet

I tried 9005 for MBIM together with apt libmbim-utils, but it did not became available.

Then I installed the standard simcom_wwan driver, which is a success.

so I see the qmi_wwan driver not running on tegra.

Someone else who did the same research:

Found a recipe patch example:

I found that there are kernel patches for XT2, but not for other Jetson controllers. Is qmi_wwan even enables on other jetson boards?

see:

Hi, indeed we are only including those patches for the TX2, and they have only been tested for a SIM7600E. We will need to add the support for other device types and test them for the SIM7600G-H. What other Jetson devices are you planning to use?

Hi Alex, yes I’ve figured that one out :slight_smile:

I see that a photon-jetson board has wwan support. Copied and pasted that in my yocto build

We are using jetson-nano jetson-nano-2gb-devkit and jetson-nano-emmc

so the .bbappend file should look something like this:

inherit kernel-resin deploy

I see that yesterday the kernel patch has been moved to all builds. I’m going to try if this fixes wwan support

Hi, I can validate that this works. Thanks!

Great, this is excellent news! Glad to hear that it works. :slight_smile:

Thanks for confirming, we’ve released v2.82.10+rev1 for the Jetson Nano (SD-CARD) which includes the change.
