won't stop trying to read bytes at bogus address when taking breakpoint

bowerymarc — Mon, 08 Sep 2014 23:01:41 GMT

I've ported a K20F120M project from CW10.5 to KDE, first 1.0.1b and now 1.1.1 and both have the same behavior, where when I set a breakpoint (at the top of a task in FreeRTOS), it takes the breakpoint OK but then will not stop:

Read 4 bytes @ address 0x00024E08 (Data = 0x0330F240)

ad nauseum. The only way to stop it is unplug the jlink debugger from the USB port.

Regardless of my code, I don't think the debugger should be doing... that!

Hi Marc,

It could be the same issue as this one:

KDS debug for K22F120M in interrupt enviroment.

Can you add

set backtrace limit 20

to your debug configuration to see if this helps?

Erich

hey that seems to have done it! thanks a million!

I wonder why KDS falls down on that when CW seems fine?
