I've followed the guide here to get timer interrupts working on a rpi 1 A
https://www.valvers.com/open-software/r ... -c-part-4/
All good. Midway through following this I though i'd just quickly set something up in the Reset Handler for fun, but and i can't really tell if it's getting hit or not - it seems either i can't wait endlessly in there or it is not getting hit (it seems to be re-reading the kernel.img from the ssd when i connect run to ground) Is it possible to hit this interrupt without calling it directly? Is it possible to have it leave it's mark somehow so that i can tell it has been hit? I guess maybe write to some memory somewhere in the handler?
