How to Increase RootFS Size to 64GB on AGX Xavier Industrial SOM

Hi,

We are testing AGX Xavier Industrial SOM.

We discovered after flashing AGX Xavier Industrial SOM with JetPack 4.6. The RootFS size is only 32GB. Please help guide about how to extend the RootFS size to 64GB.

Are you flashing your AGXI with sdkmanager and it only has 32GB?

Hi WayneWWW,

We failed to flash AGXI with sdkmanager(v1.7.1.8928) somehow. Therefore, we download the Linux_for_Tegra directory via sdkmanager only. And we use the following command to flash AGXI:

cd ~/nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_AGX_XAVIER_TARGETS/Linux_for_Tegra
sudo ./flash.sh jetson-agx-xavier-industrial mmcblk0p1

Sorry about that. That is a known issue in sdkmanager.

Could you share your “df -h” and dmesg with us?

Hi WayneWWW,

Thank you for the info.
Regarding the dmesg and df command, I attach the log. Please check it.
agxi_dmesg_df_lsblk.log (40.7 KB)

Here is the “df -h” and “lsblk” result:

If you didn’t enable rootfs a/b, then please add -S with 64G in flash.sh.

Hi WayneWWW,

I used the following command and the mmcblk0p1 could be extended to 58GiB.

sudo ./flash.sh -S 62277025792 jetson-agx-xavier-industrial mmcblk0p1

Thank you for your help.
