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?

Download the L4T from
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 ./

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

Dear Jerry:
This issue still needs support, We will be upgrading to this version soon, So it is urgent.

hello rd1,

could you please try the offline approach to flash the board?
you should assign board info to the command line for flashing.

This command is ok!
