Hi TunaHann,

Please find the from Jetson Sensor Processing Engine (SPE) Software Sources package from

I have done all the setups such as Nvidia SDK Manager, JetPack, necessary libraries. But right now I’m just asking how to install FreeRTOS on Jetson.

Hello, Tuna:
For latest Jetson SDK, NV open-sourced SPE firmware, which runs FreeRTOS.
SPE is a R5 core, in TX2/AGX. You can find SPE source code as kayccc mentioned above.
Also, you can refer to TX2/AGX TRM for hardware information about SPE core.
