I’m trying to find the sources for the Cortex-R5 Jetson Sensor Processing Engine (SPE) for Jetson Orin Nano. The latest developer guide is v36.4: Jetson Sensor Processing Engine (SPE) Developer Guide: Welcome does not have any link to the source tree.
The latest code I found belongs to Jetson Xavier NX: Compiling and flashing rt-aux-cpu-demo - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums . @DaveYYY responded in June 2023 pointing to https://developer.nvidia.com/embedded/l4t/r32_release_v6.1/sources/t186/l4t_rt_aux_cpu_src.tbz2 archive. Is it the latest? Will it work for Jetson Orin Nano?
Will it be beneficial for all developers if a link to the source code tree will be posted on the Jetson Sensor Processing Engine (SPE) Developer Guide: Welcome page?

From my observation, it seems that nVidia’s official development of SPE functionality is not so proactive and is almost on hold…
Actually, it’s a part of the “Driver Package (BSP) Sources” on this page: Jetson Linux | NVIDIA Developer : https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v4.3/sources/public_sources.tbz2 . Once you download the entire archive, need to extract the spe-freertos-bsp.tbz2 archive. The sources have January 2025 timestamp - looks like it’s still supported.

Although the timestamp is the latest, the functions inside seem to have not changed. The CAN bus is not supported yet, but it was supported in version 32.x.x.
