Hi,

We are working on agx xavier industrial and agx xavier devkit with R35.6.1.
Agx xavier industrial module has 64GB in total, but after flashing official image, mmcblk0p1 is only 28GB, while the remaining 30GB is located in mmcblk0p15.

p@p-desktop:~$ lsblk

Why?
How can I add the 30GB from mmcblk0p15 into mmcblk0p1, so that mmcblk0p1 becomes 58GB?

Thx

Hi,

We will flash the same BSP onto our AGX Xavier devkit to attempt reproducing the issue.

Thanks

Hi,
We have confirmed that our dev kit does not have this issue.
Please run ls -alh /dev/disk/by-partlabel and identify which partition corresponds to mmcblk0p15.
And check this partition in the XML configuration.

Thanks

Hi,

Please see the output of the command ls -alh /dev/disk/by-partlabel below

We haven’t made any changes toflash_l4t_t194_spi_emmc_jaxi.xml

Please help us with modifing “UDA“ partition in the XML configuration.

The attached xml is the configuration we used, which should be the same as yours.

Just a reminder, we are working with agx xavier industrial on R35.6.1.

Hi,

Sorry for the late response.

Please configure the ROOTFSSIZE to your ideal size in the p2972-0000.conf.common file.

Thanks

Hi,

I changed ROOTFSSIZE to ROOTFSSIZE=50GiB; from ROOTFSSIZE=28GiB;

and it showed the following error message at the end of flash log.

I also changed EMMCSIZE to EMMCSIZE=63652757504; from EMMCSIZE=31276924928;
It still showed the same error message.

Hi,

Thank you for your update.
Do above config change resolve the storage size problem?

Thanks
