Hello, I work for a small electronics company where we design devices with OTS components such as the Nvidia Jetson for use on our own carrier board. I have been tasked with starting the RMA process for the Jetson boards we have purchased.
Through our extensive troubleshooting process we have narrowed it down to the Jetson Orin NX hardware, as the rest of our devices function normally. During hardware assembly and testing, a handful of Jetsons began to fail in various ways. While troubleshooting them, they do not boot properly and some output specific error messages over UART, despite attempts to re-flash them with known good software.
All devices were tested and re-flashed on the same Jetson dev board.
Jetson #1: Does not appear to boot when given power, no UART output to diagnose with, and the fan does not initialize.
Jetson #2: During boot UART terminal displays “RAS Uncorrectable Error in CMU_CLOCKS, base=0xe003000:” and continually reboots.
Jetson #3: During boot UART terminal displays “Unhandled Exception in EL3.” then outputs a large list of register values. Does not proceed beyond that point.
Thanks in advance!
