About CAN on SPE or Cortex-R5 core

Hello, we want to use Cortex-R5 core on the Jetson Xavier. But our motor is controlled by CAN. Is there any support for CAN while using Cortex-R5 core?

Hello,
You can take a look at Jetson Sensor Processing Engine (SPE) Developer Guide: CAN Application (app/can-app.c) (nvidia.com) to see whether it can help.

Thank you for your reply! Our Jetpack version is r35.3.1. However, when we read the docs of spe on r35.3.1, the CAN Application can not be found. Whether the CAN is not supported on r35.3.1?
The docs we read is given below:
https://docs.nvidia.com/jetson/archives/r35.3.1/spe/md__home_gauthams_delete_spe_35_83_spe-freertos-bsp_rt-aux-cpu-demo-fsp_doc_gpio.html#autotoc_md32

Hello,
You are right.
CAN support in SPE for rel-35 is still not in.
Anyway, since all source code is open, and I think you may be able to port the CAN driver to rel-35, by referring/leveraging code in SPE rel-32.
