I’ve been porting FreeBSD to the DragonBoard 410c. I can get the kernel to start booting, however during the boot process the hardware resets. When I added verbose logging I found the reboot location is not deterministic. This makes me think there is a watchdog resetting the hardware, however I haven’t found anything in any of the dts files that look like one.
Is there something I’m missing?
I’ve pasted the current boot messages below:
