Hangs at Starting CPU & Halting co-processor

Freshly unboxed Nano not booting. Last message on serial console is “[0007.671] Starting CPU & Halting co-processor”. Sdcard imaged with jetson-nano-sd-r32.1.1-2019-05-31.zip using Etcher. Green power light stays lit. Any ideas on how to remedy this?

Hi John,

Could you try to use sdkmanager to reflash the sdcard?

WayneWWW,

Thank you for suggestion.

Imaging the sdcard using sdkmanager worked. The nano booted. I was leaning toward the nano being DOA, so I ignored that path.

After the success I tried imaging another sdcard using Etcher and the same image file identified above. My expectation was a repeat of the original complaint. Surprisingly, the nano booted just fine. Bonus: the image from the file auto-expands the root partition to fill free space. The sdkmanager generated image does not.
