Hi there, Perhaps I am an especially slow learner, but so far I have not yet figured out how to make GPIO on Jetpack 6.2.1 for Jetson AGX Orin Devkit 64GB work. Specifically I want to use SPI1. It works with Jetpack 5. Currently I have flashed Jetpack 6.2.1 with SDKManager on the nvme drive and u…

[image] studio23p62: So as the last step to build the jetson linux kernel I could copy the Image file directly to /boot/Image of the Jetson, reboot and be done? I would suggest you updating them to the BSP package first and reflash the board to apply the change in case you missed something. …

[image] studio23p62: Subquestions: Where do I find the files to be patched? Do I need to re-flash both bootloader and OS to apply the patch? Can I do this with SDKManager, or do I need to use the flash scripts in Linux_for_Tegra directory? refer this link to download the sources for updatti…

Thank you for the suggestion! This link was indeed helpful. I understand that there will be many steps involved to apply the patch. Just to document my process for the future, I think these are the steps I need to do: ▶ download the l4t sources ▶ get the cross-compilation toolchain ▶ apply the patch …

@KevinFFF Thank you for taking the time to respond! It is in kernel source, please refer to the steps in Kernel Customization — NVIDIA Jetson Linux Developer Guide to sync and build kernel. Yes, thank you. I think I found and patched them successfully following these instructions. You can simp…

Great, thank you so much for the reply! I’ll go through the workflow including the suggested BSP & oot updates and will report back here.

It worked!!! Thank you so much for your support @nagesh_accord and @KevinFFF , really appreciated. As a sidenote. There was a wiring issue on our sensor as well. The CS pin was not using the SPI1_CS0 or SPI1_CS1 as chipselect, but CAN1_DIN. With Jetpack 5 this just worked anyways. With Jetpack 6 n…

Thank you for sharing the script and I think it should be fine.
