[Jetpack-4.5.1] How to apply overlay to support Jetson Xavier NX 16GB?

Dear NVIDIA Team,

I would like to know how to correctly use the overlay to support Jetson Xavier NX 16GB in Jetpack-4.5.1 (r32.5.1), please ?

Thanks in advance and best regards,
K.

Hi,

Not sure about what is the problem here. The overlay is just decompress to the BSP directory.

Hi @WayneWWW ,

Do you confirm that I could replace the existing Linux_for_Tegra/bootloader/tegra194-a02-bpmp-p3668-a00.dtb and Linux_for_Tegra/bootloader/t186ref/BCT/tegra194-mb1-bct-memcfg-p3668-0001-a00.cfg with the new ones in the xnx-16gb-r32.x-overlay.tbz2 ?

Also, I found more than one occurrence for each file as below :

$ fd tegra194-a02-bpmp-p3668-a00 Linux_for_Tegra/bootloader/
Linux_for_Tegra/bootloader/t186ref/tegra194-a02-bpmp-p3668-a00.dtb
Linux_for_Tegra/bootloader/tegra194-a02-bpmp-p3668-a00.dtb
$ fd tegra194-mb1-bct-memcfg-p3668-0001-a00  Linux_for_Tegra/bootloader/
Linux_for_Tegra/bootloader/tegra194-mb1-bct-memcfg-p3668-0001-a00.cfg
Linux_for_Tegra/bootloader/t186ref/BCT/tegra194-mb1-bct-memcfg-p3668-0001-a00.cfg

I wonder which one should be replaced ?

Best regards,

Generally, the overlay tarball is already the file we validate on the same branch…

You don’t need to check the path or file name…the file already set that for you… just compress it and the file location should be correct.

Also, it seems you don’t know what is the difference between the one under bootloader/ and bootloader/t186ref.

I would suggest you can download a clean BSP first. Check the file. And then flash the board again. Check the path again, and you will know the answer…

If you still don’t know, come back, I will share the answer then.
