Hi,
If you follow developer guide to extract the source code to ~/jp61/Linux_for_Tegra, you would need to do like
Can't receive file via Bluetooth on Jetson AGX Orin with JetPack 6 - #29 by DaneLLL
So suggest create a non-root path and extract to the folder:
Building the kernel from kernel source jetpack 6 , jetson orin nx 16GB - #5 by DaneLLL
Either method is good.
