flash-log.txt (11.7 KB)

hello rd1,

it seems some Boot Rom communication failures.
may I know what’s the commands you’re used to flash Nano-eMMC,
are you installing JetPack-4.5.1 with NVIDIA SDK Manager | NVIDIA Developer?
thanks

Download the L4T from L4T | NVIDIA Developer
Make the system as the document.

  1. $ tar xf Jetson-210_Linux_R32.5.1_aarch64.tbz2
  2. $ cd Linux_for_Tegra/rootfs/
  3. $ sudo tar xpf …/…/Tegra_Linux_Sample-Root-Filesystem_R32.5.1_aarch64.tbz2
  4. $ cd …
  5. $ sudo ./apply_binaries.sh

flash the system
6. $ sudo ./flash.sh jetson-nano-emmc mmcblk0p1

hello rd1,

we cannot reproduce the issue locally,

I have several questions as below,

  1. could you please double check you’re downloading t210 series rootfs package?
  2. is there return a success when running apply_binaries script?
  3. is this board fused to enable secureBoot?
  1. I download the package from the official link L4T | NVIDIA Developer, and use it directly without rename.
  2. apply_binaries.sh complete successfully.
  3. This board don’t enable secureBoot, I have mentioned that I flash my device well with 32.4.2 as the same steps.

hello rd1,

please flash the board as following configuration file to see if any difference,
for example, $ sudo ./flash.sh jetson-nano-devkit-emmc mmcblk0p1
