设备设置成nvme启动或者mmcblk1p1启动,mmcblk0p1是否可以格式化或者删除内容

Hello, I’d like to ask what’s the substantive difference between external startup and internal startup. Can mmcblk0p1 be completely formatted or sudo RM - RF *? I’m starting an external hard disk now. After formatting, the device crashes. What’s the role of mmc0p1 after setting it to external startup? Jetpack4 Version 5, NX core

Which platform are you asking?

您好我使用JETSON NX设置外部启动。L4T3251,JETPACK4.5,使用外置emmc启动不使用设备自带的mmcblk0p1了,外置的是mmcblk1p1,dd /de/mmcblk0p1 of=/dev/mmcblk1p1 ,sudo vi /boot/extlinux/extlinux.conf可以正常启动为emmcblk1p1,df -h查看根文件已经是emmcblk1p1,但是想清空emmcblk0p1却不行,清空以后设备就无法启动了,是有什么重要的文件还一直在emmc0p1分区内吗

Then you filed the topic in the wrong forum. Let me move your topic to Xavier NX forum.

I think the problem is jp4.5. Which does not support to boot from nvme.

And no matter which version, the cboot does not support your extra emmc.
