Hi ,we used R32 (release), REVISION: 5.2, GCID: 27767740, BOARD: t210ref. We have a serious problem: the nvidia module cann’t start, no reaction at all when power on. The module had run sometimes normally, but it suddenly won’t turn on. We connet the uart, but without any information. We had fou…

Hi, we want to just flash the cbbot.bin for the boot up failed board, and it flash failed. We got the flash log: 1s1191_update_cboot_failed.log (4.1 KB). It had these errors: [1216_10:57:30][0010.105] Loading NvTbootBootloaderDTB [1216_10:57:30][0010.121] Verifying NvTbootBootloaderDTB in Secur…

It looks something wrong with your cboot image. How do you flash cboot.bin only? Could you flash all on failed board successufully? Or just flash cpu-bootloader failed?

we used the cmd to flash cboot.bin on normal board, it flash succseefully. The cmd is: sudo ./flash.sh -k EBT -u ./Product03/rsa_priv.pem jetson-nano-devkit-emmc-smpsq mmcblk0p1. We had tested to flash all image files on the failed board , it can flash successufully, and boot up ok!

Where is the rsa_priv.pem come from? Could you try the following command instead? sudo ./flash.sh -r -k cpu-bootloader <board> mmcblk0p1

Our board had burned efuse with PKC key. we are Nano product, we had checked the cmd on another case( How to flash cboot only ). And we had tested the cmd on normal board, I think it is ok.

We didn’t used VM ,we know VM’s error. We had flashed successfully on normal board. I think maybe the emmc had bad block, because the board could bootup after reflash all Image bin.

We want to check the emmc bad block by flash cboot.bin only. It flash cboot.bin failed, and had the error logs.

[image] yong.lu: [1216_10:57:30][0010.145] Error in NvTbootLoadBinary: 0x14 ! Do you still have these errors when you flash cboot.bin only?

There are some users encounter the similar issue, but they resolve with different host PC.
Unable to flash: Error: probing the target board failed. and boot: Error in NvTbootLoadBinary: 0x14 - #17 by linuxdev

Are you using the VM with Ubuntu or standalone x86-64 Ubuntu?
and what’s your Ubuntu version?
