We designed a custom carrier board for the Jetson Nano. We purchased the production SoM that uses the eMMC rather than the SD card for the boot. When we tried to boot the production SoM without flashing anything , we could see an “Android Boot Menu” and then the screen proceeds to “Continue Booting…” and then nothing happens. We hooked up the debug UART console to get the boot log and we got the SSH to the carrier, which we confirmed by issueing basic commands like “reboot” and “poweroff”. The board responds as expected.
Nextly, we flashed an SD card on the A02 DevKit, and made the initial set up like username password etc. Then we connected this A02 module with SD card, onto our custom carrier board. Here we dont see any display coming up. However, we were able to get the boot log, again the boot proceeds to home screen, verified by login with username password, basic command issue like “reboot” & “poweroff” via SSH. Here also the board responds as expected but we are not getting any display.
Kindly help me understand the following:
- What image is programmed in the B01 Production SoM (w/o SD card)?
- What is the procedure to flash the production SoM?
- Is the same image applicable to the flash of the production SoM?
