Modify sdcard image size from 16GB -> 2.3GB

[EasyIP2023]

Basically I have a custom layer with a .conf file that changes these two variables

ROOTFSPART_SIZE ?= "2000050000"
TEGRAFLASH_SDCARD_SIZE ?= "2200M"

When I generate an sdcard image via ./dosdcard.sh this works fine on branch dunfell-32.4.3. I'm able to boot into image and mount on local machine with no problems, but on branch dunfell-32.5.0 when I select machine=jetson-nano-2gb-devkit and do the same thing. It resizes the sdcard image, but I can't boot into it or mount it on local machine. When I select machine=jetson-xavier-nx-devkit it doesn't create the image at all. Just wondering if there's somewhere else on branch dunfell-32.5.0 that allows me to modify the size of the sdcard image?

This is how far it gets to on machine=jetson-xavier-nx-devkit before stopping itself.

IIRC, the flashing tools in L4T R32.5.0 pay more attention to the num_sectors attribute in the <device> elements of the flash layout XML file. A mismatch between that file and the actual number of sectors on the card could potentially lead to booting problems, so you might need to use a customized layout with the correct sector count.
