We have some questions about the use of sdmmc3, hope you can provide some guidance.
Now, we have successfully enabled sdmmc3 in Jeston Xavier NX emmc. It can be I/O or used as rootfs.We used this approach in the forum.
Although it is working now, we still have some questions about it：
Can we copy the content in the SDCARD that has been used to get a SDCARD with the same content? And bootup from this new SDCARD? .We have tried to copy a used rootfs to another card through the command “sudo cp -a * && sync”. Unfortunately this doesn’t work.
We hope to make an image file containing some software, and it can be copied to more SDCARDs to boot NX.Can you give some suggestions?
You seem to mention in the forum that external storage cannot be upgraded via OTA
Can this problem be avoided ?
