TX2 p3310 (P / n135-0807-003 R2) module is used in our product, and all functions are normal before. A batch of TX2 p3310 (P / n135-0807-003 R1) modules purchased recently have errors when executing flash.sh.
the flash cmd is: sudo ./flash.sh -r jetson-tx2 mmcblk0p1.
the error info is: “CPU Bootloader is not running on device.”
Why did this error occur and how can I fix it？
