I’ve got a TX2 which all of a sudden is reporting “bootconsole disabled” and not continuing to boot. I’ve attempted reflashing from Jetpack 3.3 multiple times with the same result. Is there any way to debug and/or totally reset the TX2 to try and fix this?
Do you have a serial console log? This would provide some valuable information.

It’s as if the CPU core itself has failed. So far as I can tell the core just stopped and never ran. Normally I would suspect something with the flash, but I doubt it could get this far the way it has without a hardware issue.
One thing you might test is to see if you can clone. This would be basic functionality from the first core, along with eMMC if it can clone. See:
https://devtalk.nvidia.com/default/topic/1000105/jetson-tx2/tx2-cloning/
Note that earlier releases will have some differences in cloning versus newer releases. The R28.2+ should be ok without flash.sh patching, but you might mention which release the TX2 was running prior to the trouble.
I’ve actually tried cloning and re-flashing a few times using that procedure, as well as just re-flashing from jetpack. The clone/flash seems to work fine, but it always fails here.
Is this an RMA issue?
No issue on my side. How about using other Jetpack release? Jetpack3.2 or 3.1.
Do try another release. I would be somewhat surprised if clone works for a case of the first core actually failing.
Btw, are you using the original power supply?
I tried jetpack3.1 with no success. I am using the original power supply.
Anything else to try?
I personally cannot think of anything more to test. It may be time to RMA. Perhaps someone who knows the details of why it might stop instead of proceeding to this might have another suggestion:
Booting Linux on physical CPU 0x100
I think you could trace the kernel boot up log and see where does it hang.
rel-28/kernel/kernel-4.4/init/main.c → void __init start_kernel(void)
If you decide to go the route mentioned, then you might find this printk tutorial of use:
https://elinux.org/Debugging_by_printing
FYI, you’d rebuild the kernel using the same starting config (see “/proc/config.gz” for this) and set a brand new CONFIG_LOCALVERSION, build the kernel and modules, and install those. Use a new extlinux.conf entry so you can pick this kernel on command line at boot instead of making it default.
If you go to file “init/main.c”, near line 498, function “start_kernel” begins. The actual message “Booting Linux on physical CPU” which is missing is from a call to “smp_setup_processor_id” near line 508. Either that function is not being entered, or else when entered it hangs. You could put a printk prior to the call of that function to say it is about to be called, and then some printk statements throughout smp_setup_processor_id to see when the failure begins. File “arch/arm64/kernel/setup.c” contains “smp_setup_processor_id” near line 94. You’d put a printk before and after each call of an outside statement.
