how to resize partitions app in jetson tx2，I Want to Reduce the app partition size and create a new partition

You can check some old posts like this.

The method should be still same on rel-32.

  • Flash.xml generation is based on Flash L4T T186.xml，Changing flash.xml makes no sense
5

Good, then change the one that would take effect.

6

I Have try to change flash_l4t_t186.xml, but write to system.img with flash.sh and it gets stuck，like this:


<allocation_policy> sequential </allocation_policy>
<filesystem_type> basic </filesystem_type>
21474836480
<file_system_attribute> 0 </file_system_attribute>
<allocation_attribute> 0x8 </allocation_attribute>
<percent_reserved> 0 </percent_reserved>
<align_boundary> 4096 </align_boundary>
<unique_guid> APPUUID </unique_guid>
APPFILE
Required. Contains the rootfs. This partition must be defined
after primary_GPT so that it can be accessed as the fixed known special device
/dev/mmcblk0p1.

7

Or you can use the default xml file with -S in your flash.sh.


         -S <size> ------------ Rootfs size in bytes. Valid only for internal
                                 rootdev. KiB, MiB, GiB short hands are allowed,
                                 for example, 1GiB means 1024 * 1024 * 1024 bytes.
8

*I’ve already used this method and running flash.sh is also stuck

9

What is the size of your system image?
What is the jetpack release version?

Could you dump both the uart log and host log when flash fails?

10

the size of my system image is 21143708372 byte, and the jetpack release version is JetPack_4.5.1_Linux_JETSON_TX2,
Operation instruction is :sudo ./flash.sh -r -S 23GiB jetson-tx2 mmcblk0p1,
here is th flash fails log:
[ 22.9321 ] Writing partition APP with system.img
[ 1026.2622 ] ] 000%
Error: Return value 3
Command tegradevflash_v2 --pt flash.xml.bin --create
Failed flashing t186ref.

11

Can you dump the uart log during the flash?

Do you change both xml file and “-S” in flash.sh now or you only change the “-S” in flash.sh?

14

only change the “-S” in flash.sh

16

Can you please do not use “-r” in flash.sh?

17

like this:
sudo ./flash.sh -S 23GiB jetson-tx2 mmcblk0p1
?

18

Hi 673765403,

Please try below steps:

1. Edit Linux_for_Tegra/bootloader/flash.xml
    --> change APP size to 23GiB
2. Run below command to flash:
    $ sudo ./flash.sh -S 23GiB jetson-tx2 mmcblk0p1

We confirm it’s working and boot up success.

  • This method is proven to work. Thank you

use below steps: ./flash.sh -S 23GiB jetson-tx2 mmcblk0p1, *A new image is created each time ,But I’m going to use my own system.img.How do I do that
