Hard fault in STM32H7 protected mode #1409

Open hexaglow opened 4 years ago

hexaglow commented 4 years ago

Configuration: stm32h747i-disco:nsh. The system hard-faults on boot, and I haven't been able to track down the cause. It seems to occur after a supervisor call for a boardctl but I can't see any obvious reason why. I suspect stack corruption but can't tell where it is happening. My .config is below, that should be enough to reproduce, I have no extra applications or code in this build.

My .config and the stack dump is here

@hexaglow unfortunately I do no have this board to be able to reproduce this on hardware (none of the h7 series). If you attach the elf with debug symbols (and an updated fault report) I might be able to get a little more information. I suspect you have already worked through some of this but there is this resource here as well: https://cwiki.apache.org/confluence/display/NUTTX/Analyzing+Cortex-M+Hardfaults

@povauboin You had some some board support work for this would you be able to provide any insight sine this is a standard configuration.

@hexaglow I now have a NUCLEO-H745 so I will try the protected build this week. I did not have any H7 hardware before, hopefully we can figure out what is going on.
