Registers values not shown while debugging in MCUxpresso

tomato — Tue, 27 Dec 2022 13:26:50 GMT

Hi all,

I am a new user of MCUXpresso IDE and I would like to know how to see the peripherals registers while debugging. As you can see from the screenshot attached the values of the registers are not showed. Can you help me? Am I doing anything wrong?

I am using the LPC845 BRK with the standard debugging set-up provided with the development board.

Your target is running: halt/pause/suspend it first.

Thanks erich. I see.
Can you show me the way to see the values while the target is running?

Thanks eric. Now I can have a live monitor of a global variable (as described in the link you shared)
Is there a way to see the actual registers value while running? (I mean in the window on the left in the first image I posted)

No, that window cannot support live update of the registers: that would be way too intrusive.
