Flash agx xavier

I try to flash agx xavier with sdkmanager, and after flash finished, the agx xavier can not start. there is some error ,such as:
Failed to start NVIDIA specific early first-boot script

This looks like a Jetson issue, moving it into Jetson AGX Xavier forum for resolution:
Latest Jetson & Embedded Systems/Jetson AGX Xavier topics - NVIDIA Developer Forums

Please remove the whole Linux_for_Tegra downloaded by sdkmanager and let it re-download and re-flash again.
