Initially healthy Jetson Nano that has been operating without any issues, after next boot
Jetson Nano stopping to boot at process and stays there without finishing :
EMC Training (SRC-freq: 204000; DST-freq: 1600000)
Fan is on and at 50% Duty Cycle. Development Carrier Board is healthy, everything regarding setup is tested and verified to be healthy with other operating Jetsons.
It is not known but is possible that short has happened on the SoC which could affect on external memory controller where it stops the process.
Tests are preformed:
- Resetting manually from SYS_RESET == Will not boot to kernel
- Force recovery mode == Will enter to recovery mode
- Serial console on Normal boot == Processes until EMC Training (Then stops)
- Jetson image cloned to investigate == Cloning successfully completed; image is not flashed on other devices to be tried out
- Reflashed Jetson Nano == Reflashing successfully completed; Does not boot, the identical issue continues, stops at EMC Training
