Root device found mmcblk0p1, ERROR: mmcblk0p1 not found

I am a new user. I proceeded by following the steps on the site Initial Setup | CircuitPython Libraries on Linux and the NVIDIA Jetson Nano | Adafruit Learning System .After doing the set user permission steps, I rebooted and then I got the following errors, ubuntu did not open. I think I’m stuck at the GNU bash screen. I am attaching the error I am getting.

Could you help? I can’t find what to do. How can I fix this problem.

There are two kinds of Jetson modules. Do you use the module with embedded eMMC? Or with SD card slot? For using the module with SD card slot, you would need to prepare a SD card with size >= 32GB.

Thank you for your reply.

I have the SD card slot and I am using it with 32GB SD card.
I haven’t had any problems before that. As I mentioned above, I did what needed to be done step by step. I encountered this problem after rebooting after doing the part of set user permissions. Last I typed “sudo cp ~/jetson-gpio/lib/python/Jetson/GPIO/99-gpio.rules /etc/udev/rules.d” then rebooted. I don’t know what to do next.

It is uncertain what status of the board is. We would suggest re-flash the system image through SDKManager and try again.

If you would like to run deep learning inferences, may consider use DeepStream SDK.

Actually, I didn’t get the answer I wanted. I will repeat the operations using an sd card again. If I have a problem again, I will open a new topic. thank you.
