Usage of full SD Card Capacity on Jetson Nano

[martin.probst]

Hi,

I have an issue with the usage of a 128GB SD card and already followed some advice on Jetson nano showing 16GB instead of 64GB - #3 by snarky but without success.

Procedure

1. I generated an image using the Nvidia command line tool after having learned that the SDK Manager does not make use of the full capacity of a large SD card (for whatever reason).
2. This image I burnt using Balena Etcher on a OS X machine.
3. Then I expanded the partition table on a Ubuntu 22.04 using gparted

Situation of the SD card on Ubuntu Host Machine
Host machine yields 119.08 GiB card size.

Situation of the same SD card from within Jetson Nano
Jetson only yields 14.7 GiB card size.

Does anybody have a clue what is going on here? I have been fiddling around with getting Jetson Nano software up and running for days now and I would be really glad to start doing something more meaningful ;-)

Regards,
Martin.

Sorry for the late response.
Is this still an issue to support? Any result can be shared?

Are you using Jetson Nano with eMMC? Is the SD card slot on the module itself or on the carrier board?
If it’s the eMMC module, I believe the 14.7 GB capacity comes from the eMMC, but not the SD card.

Thanks for reaching out. You’re absolutely right. After hours of digging in the wrong direction I found out that I am using a Waveshare board with an eMMC and SD card slot on the carrier board. Thus, the limitation came from the eMMC and the comparison I made in my original post was totally wrong (comparing eMMC with SD card). In the meantime I also got an original Jetson Nano Developer Kit from NVIDIA where there is no eMMC and the SD card slot is on the computing module itself.
I guess this is all described somewhere but it was not that obvious to me.
