@atax1a from my limited knowledge using swd, what would i see without an attached debug source code? just registers changing? how would i tell what's working?

@atax1a we do have a j-link but very little idea how to do what with it

i realize how likely it is that voltage sensitive parts such as CPU, RAM or flash are probably cooked. but i'd really like to bring it back if at all possible

so i have a broken chumby classic (ironforge 1.8: http://files.blueocty.com/hdwedocs/IRONFORGE_MX21_V1_8_FINAL.pdf ). in some sort of fashion, there was a short in a power rail somewhere (i suspect DC in and ground, but i'm not sure if so, or if that was indeed the root cause) which blew a diode and some buck regulators. i have now replaced all those parts and checked that all voltages (5v, 3v3, 1v8) are correct and the unit does power on however never functions beyond a white screen

spitballing appreciated ​
