According to #4(thanks to @ADV-LUT), the current script does not correspond to R32.2.0.

It seems like the new version of L4T, R32.2 uses a new dts.

I've used dd to replace the required partitions and move back and forth between standard and spi-enabled system. basically, just used the 5 partitions that change: p3, p4, p5, p9 and p10.
would it be possible to set this up such that we can just run a script using pre-built partition images straight from the device itself?
thanks
