>>why?
I haven't worked on my telekinesis for several decades..
Perhaps you have a UART, or some other means of data output, that you can use to output telemetry or diagnostic information, absent a hardware debugger, and then use that to make some failure diagnosis or test theories about why it doesn't work as expected.
Have something useful output by the Hard Fault Handler, and Error Handler routines, so you can learn if it ended up in either of those places.
Up vote any posts that you find helpful, it shows what's working..
