Good Day,
What is the documentation or training to install or configure FreeRTOS for Jetson TX2?

2

Have searched through the forum and the net. There is a myriad of information which is not much help. Hoping for a paid training of some kind.

3

Moving this to the Jetson TX2 topic where you are likely to get better support.

Thank you.

For TX2 L4T, AON R5 is open for public use, with FreeRTOS source package released.
You can search ’ Free RTOS Sources’ for details, and some simple guide/sample code are also included.

Discovered some information regarding FreeRTOS on Jetson’s Arm Cortex-R. Is there another RTOS that is provided with Nvidia’s Jetson Development Kits?

9

In the past, I have used openOCD (https://openocd.org/) to flash (load) the FreeRTOS’s executable loadable format (ELF) file onto the ARM Cortex-M4 MCUs. How does one load this file on the particular ARM Cortex-A5 MCU of the jetson Development Kit.

I’m afraid not.
So far, TX2/L4T only has following cores open for public use.

  1. CCPLEX (A57), with bootloader/Linux
  2. SPE R5 (in AON cluster), with FreeRTOS sample code.

Other cores are only for internal use.

Found “Jetson Sensor Processing Engine (SPE) Developer Guide: Welcome”. This appears to be the same as the ‘FreeRTOS Source’ link provided earlier.

I have produced a '‘rt-aux-cpu-demo/out/t18x/spe.bin’ file. The next step is copy this file to ‘Linux_for_Tegra/bootloader/spe.bin’ location. I guess the ‘Linux_for_Tegra’ is the flashing platform. Please provide an nvidia link to download the Tegra.

The Quick Start helps a great deal. Many thanks.

I understand that the Nvidia’s Secure Boot on Jetson platforms prevents unauthorized boot code. It uses Public key Cryptography (PKC) keys. Looking for the limitations by reading through https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3275/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/bootloader_secure_boot.html#wwpID0E0LH0HA. Is there an alternative to the Nvidia’s Security Boot solution, since Unified Extensible Firmware Interface (UEFI) has replaced BIOS.

Hello,
Can you restart a thread for the new query?
One topic for one thread may make it easy to backtrace.

Thanks.
