Some errors about the start of TX2 system

I can’t start the TX2 system because it hasn’t enough disk space.Also,I can’t flash it by Jetpack again.Can you give me some advice ? How can I start it successfully again ?

Is there a reason it can’t be flashed? If you just mean you can’t afford to lose the root file system, then this can be worked around (clone, free space on the loopback mounted raw clone, and then flash the fixed rootfs). If you mean you can’t put the Jetson in recovery mode and manipulate it over the micro-B USB, then it gets difficult. Which case applies to you?
