Hello, I’m flashing my Jetson Orin Nano Devkit using l4t_flash_initrd.sh script (direct flash to NVMe). I’m experimenting with the rootfs contents currently and re-flashing the whole system root image takes quite a while, because each time the whole 128GiB+ image is written to the NVMe drive, and I need to do this on multiple devices.
So my idea is to somehow have the scripts only create an empty partition for the rootfs without populating it and then use cryptsetup+gen_luks_passphrase.py to manually copy the data into the partition without needing to write the whole encrypted blob. Is it possible with l4t tools?
Hi,
Sorry, our official tool not support it.
To make flashing process faster, you could refer to the Linux_for_Tegra/tools/backup_restore/README_backup_restore.txt Workflow 3: To massflash the backup image.
Thanks
