Hi, I would like to update the TensorRT version on my Jetson device to TensorRT 7.2.1 since it has some optimizations I need. I see that there are some prebuilt ARM packages for TensorRT 7.2.1 for Linux and CUDA 11.1, but JetPack 4.4.1 has CUDA 10.2 installed.

Do you have a prebuilt TensorRT package for CUDA10.2? Or, is there a release date for the new Jetpack version which will include the newer TensorRT version?

Hi @ivan.ralasic, those packages are for ARM SBSA architecture (ARM server), and not Jetson. Jetson uses integrated GPU whereas ARM server uses discrete GPU over PCIe. The version of TensorRT is specific to the version of JetPack. We don’t yet have a date to share for the next upgrade to be released, please stay tuned.

Hi,
I need to set up Jetson Xavier AGX by installing Jetpack. I have downloaded and ran the SDK manager for Jetpack 4.4.1 as per the instructions to install Jetpack components on the Xavier board.
While running the SDK manager, the step for ‘Flash Jetson OS’ under Target components was skipped accidentally by me and the installation of all other components completed successfully.
I want to know if I can still use the Jetson SDK components like CUDA and Deepstream on the Xavier board as standalone (without host system) as it was able to boot up and has Ubuntu running.
Is it required to flash Jetson OS to use the libraries installed with Jetpack? If yes, can I run the SDK manager again and just run the step to flash jetson OS to the device? Or is it required to reinstall the Jetpack SDK components after flashing the Jetson OS?

Please provide suggestions on this.
Thanks.

Hi @akshara.ravishankar2, i am guessing you already has a JetPack running on your AGX. If so, host system was already there. Though JetPack components from JP 4.4.1 installed properly, it might not work properly if the BSP (L4T version) is older. So i would suggest to reflash again with flashing OS and installing JetPack components.

I reflashed it again and again. Your sdk manager tell me every time that installation successfully completed. But device in boot loop. Wtf?!
