Jetson Nano not responding correctly anymore

To who may concern,

we are having several failures concerning jetson Nanos. They do not work correctly after a period of time.
We have multiple jetson nano and we can easily flash them all. We succesfully flashed them all before, and now some of them are not working despite there being any changes in the flashing procedure from our side. We still can flash other new jetsons.

From the technical side:

  1. We decided to flash them again because we were unable to update/change any data on them due to an error stating that all files are in read-only mode. If we try to remove something, it does not get removed and restores itself after rebooting the jetson.

  2. Flashing is stuck in the middle of the process. We tried to use new boards. Boards are all working fine, since no problem is encountered with working jetsons.

  3. Connecting a monitor to the board does not display the Nvidia logo on the problematic jetsons, instead as it should normally appear.

The behaviour of the failure is similar in all the Jetsons we are having trouble with. Therefore, we would like to send to you some Jetson Nanos and have the specific hardware problem analysed.

Thank you for your support,

Hi,

Just to confirm, does your “flash stuck” mean your run sdkmanager to flash them and it got stuck?

Is it on custom board or devkit?

Hi, thank you for your reply.

The boards we are using are the “JNX30” by Auvidea.
We are flashing from the terminal,
We pulled jetpack via NVIDIA SDK, and then go into “~/nvidia/nvidia_sdk/JetPack_4.6.2_Linux_JETSON_NANO_TARGETS/Linux_for_Tegra”
and flashed as
“sudo ./flash.sh jetson-nano-emmc mmcblk0p1”
We tried with jetpack 4.4 4.5 and 4.6

Is their carrier board able to dump the UART serial console log?

Would like to see what error you saw on host side and also the UART log (device log) during flash.

Looks like a hardware issue that the emmc has problem.

Hey @WayneWWW , will it be possible to use the board with other modes, for example booting from Network or micro-SD card? Or is the board unusable if the EMMC has a problem?

If this is emmc module, then not possible to boot from network or sdcard.
