Hi Nvidia Support Team,

There is a issue with the Booting. While I am trying to ON my Jetson Nano, I am getting an Issue as:

The SD card read is failing. Can I verify this is the SD card model, without eMMC?

If you connect the SD card to another Linux PC host, is it able to mount and read the SD card without error?

Hi @linuxdev,
Thanks for your response.

I am using a Jetson Nano Production kit which comes with 16 GB eMMC 5.1 storage (https://smartcow.ai/en/products/cerberus-anx/). After flashing it with the Jetpack 4.4, there is only a few memory space left, so I have inserted a 64 GB SD Card in the SD Card slot inside the casing.

I am not sure why this issue suddenly appeared after starting the Jetson Nano. Can you please assist with the next steps to follow?

Thanks in Advance

From another computer, if the SD card shows up on that other computer as “/dev/mmcblk0”, what do you see for this command (adjust for the actual device name on the other computer):
sudo gdisk -l /dev/mmcblk0
lsblk -f /dev/mmcblk0

Just knowing if those work without error is useful information. Actual output from those commands would also be useful.

Hi @linuxdev,

I have edited the /etc/fstab file and commented out the line which mounts the sd card, and the error has been resolved.

Thank you
