Sierra EM7565 drivers?

Hello,

I’m trying to connect a Sierra EM7565 driver, by USB, to the Jetson. It seems that some drivers are missing.

me@jetson:~$ uname -a
Linux jetson 4.9.140-tegra #1 SMP PREEMPT Tue Apr 28 14:06:23 PDT 2020 aarch64 aarch64 aarch64 GNU/Linux

From the list I’ve collected, I believe I’m missing the cdc_wdm, cdc_acm and qmi_wwan modules. I’ve gone over the .config file in the kernel headers directory, and from what I can see:

  • cdc_wdm (configured with USB_WDM) and cdc_acm (USB_ACM) are actually configured to be compiled as modules. Never the less, they are missing from the actual filesystem.
  • qmi_wwan was not configured to be compiled.

Is there a way to get those modules aside from compiling them myself? If I do need to compile them myself, where do I get the kernel source Nvidia used for the Jetson?

Thank you,
Shachar

Hi,
We have steps for building kernel. Please check Kernel Customization in developer guide.

Thank you. I’ve compiled the module externally. I have another problem, but I’ll open a separate thread about that one.

Here’s the other topic, if it’s relevant:
