Commercial-grade Jetson AGX Orin 32G

The system information is shown as follows:

name:orin

Disk Capacity:64G

OS Name: Ubuntu 20.04.6 LTS

Jetpack:5.1.3

L4T:35.5.0

P-Number:P3701-0004

1、Question: When the system disk occupancy rate is 40%, the total size of the cloned img file is 24.7GB, as shown in the figure:

2、Question: When the system disk occupancy rate is 80%, the total size of the cloned img file is 60.3GB. Moreover, the image cannot be burned into the module, which exceeds the 59,301,864 capacity of the module itself. The prompt is shown as follows:

Question: Why is there such a significant difference in the size of the cloned img images when the system occupancy rate is 40% and 80%? What is the reason for this??

In order to separately identify the cloned images, the cloning instructions are as follows:

sudo ./flash.sh -r -k APP -G ritrontek.img jetson-agx-orin-devkit mmcblk0p1
sudo ./flash.sh -r -k APP -G ritrontek1.img jetson-agx-orin-devkit mmcblk0p1
