I want to boot the Xavier NX Production Module from an external SD card.
In JetPack 4.5, is it now possible to boot from an external SD card instead of eMMC?
Or is rootfs only supported for porting to external SD card?
Hi,
Do you have a sdcard slot on your carrier board?
If you have it, then you can try the method on this page.
Hi,
Thank you for your reply.
Right now, I only own Devkit.
When I move to Production Module in the future, I want to use the same SD card that I use in Devkit.
It seems that the method you described looks like a way to port only the rootfs to the SD card.
In this way, the Production Module will boot via the implemented eMMC, right?

This would be different then since the sdcard based module on devkit is using sdcard to boot.
However, on emmc module, the sdcard may not be the one to boot up. You may need further configuration then.

Yes, this method only mount the rootfs to sdcard. There is no method to totally put the whole system/bootloader on sdcard.
Are there any plans to support SD card boot in future JetPack updates?
Hi,
Unfortunately, there is no plan now. Even the sdcard module is not fully booting from the sdcard directly.
