<![CDATA[How to debug backtrace under Arduino]]>Hi,
I'm a new user using an M5Core2 with the Arduino software as it's recommended in the documentation.
I'm facing an issue and I don't find any way to debug backtrace stack.
I tried with Esp Exception Decoder but I always receive this kind of exception:

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.
Core 1 register dump:
PC      : 0x400fb127  PS      : 0x00060730  A0      : 0x800d1750  A1      : 0x3ffb1f30  
A2      : 0xf3ef10b2  A3      : 0x00000064  A4      : 0x00000001  A5      : 0x3ffc8708  
A6      : 0x3ffb8798  A7      : 0x00000018  A8      : 0x800fb14e  A9      : 0x3ffb1ed0  
A10     : 0x3ffb3500  A11     : 0x400fa95c  A12     : 0x3ffb3524  A13     : 0x3ffb353c  
A14     : 0x00000001  A15     : 0x3ffc7a04  SAR     : 0x0000001a  EXCCAUSE: 0x0000001c  
EXCVADDR: 0xf3ef10d6  LBEG    : 0x400f8d01  LEND    : 0x400f8d14  LCOUNT  : 0x00000000  

ELF file SHA256: 0000000000000000

Backtrace: 0x400fb127:0x3ffb1f30 0x400d174d:0x3ffb1f50 0x400d1b9a:0x3ffb1f70 0x400d1e9d:0x3ffb1f90 0x401065bd:0x3ffb1fb0 0x4008b70a:0x3ffb1fd0

Is there a way to make these exceptions more human friendly? I don't know what to do with it, and it's funny because the ELF file is always 0000000000000000.

It looks to me like a lot of functionality must be developed for the Core2. As the firmware is being improved from earlier versions, I'm experiencing a lot of odd problems in UIFlow online and desktop, with connectivity, response to touch input, failure to execute subroutines, etc., which seem to be improving with each new release.

I expect the Arduino libraries to improve over time as well, but until these are known to be functionally complete, I am avoiding the Arduino RAD environment, mainly because it is not designed for (WYSIWYG) graphics.
