Recently there has been some memory changes in the latest Jetson Nano which requires a patch to work with the memory. The patch I have received from my distributor is for Jetpack 4.6.5, but the JetPack I need is 4.4.1, don’t what to do and how to resolve for this. This sudden unannounced change was unexpected.

Not sure which PCN you mentioned, if that’s PCN211181, then please apply the package to requested Jetpack versions:
Jetson Linux R32.7.5 | NVIDIA Developer
Additional Files
Overlay_PCN211181_r32.7.5.tbz2

The package can be applied directly to boot Jetson Nano developer kit. For custom board, please do

  1. Apply Linux_for_Tegra\bootloader\t210ref\BCT\P3448_A00_lpddr4_204Mhz_P987.cfg
  2. Apply the patch hardware-nvidia-platform-t210-porg.patch to build dtb files and put to
    Linux_for_Tegra\kernel\dtb
    Linux_for_Tegra\rootfs\boot

Need the overlay file for PCN211181 for JetPack 4.4.1

Will the same overlay file for Jetpack 4.6.5 work with Jetpack 4.4.1?
