Are you trying to mount some external disk?

[rd1]

we have a SSD plugged in carriar board, but we were not trying to mount it during boot, not implied in fstab, or any other services. but from the log, I just noticed some error reporting:

[0002.423] device_query_partition_size: failed to open partition sdmmc3_user:BMP !
[0002.431] BMP partition read failed!

I wondered if the EMMC unit went wrong after a long-term QA verification.

Then please just flash it with the BSP again.

Hello,

I have an alternative to the Jetson nano devkit from Waveshare and when I boot it up and plug in my display to HDMI, I see the same Android boot menu. This version of the devkit comes with an EMMC module so I am wondering how I would flash it. I can always use an SSD or a USB drive to set it up if that is needed, but I have been confused about this process.

Thanks,
Daniel

Finally, I fixed it by following this tutorial: https://www.waveshare.com/wiki/JETSON-NANO-DEV-KIT. What I would add is that when it asks you manual or automatic setup in the sdk manager, answer manual, but don’t do what it tells you to. Continue following the tutorial and do not change your configuration until the flash is done.
