After DS-5 connected to target, "Debug Control" tab shows "Cortex-R5_0#1 running", but "Commands" tab shows
"ERROR(TAD9-NAL30): ! Unable to stop device Cortex-R5_0! Cannot stop target."
in response to "stop" cmd. Any idea about it? what issue usually causes this?
Thanks
James
Hi Kaiyou,
I am using ARM DS 2021.2 and DSTREAM ST as debugger probe, on a real chip, and is my first time to use an ARM debugger to talk to it, and it happens 100%. It was set as "connect only" and "stop" is the only cmd in "execute debugger commands" box. I have captured daplog and will send it to you. Thanks for help!
Hi James,
Thanks for your log. I can see the debugger has already try to halt the processor by write 1 to the DBGDRCR[0], but the Core doesn't give response, I suspect the Core already hangs when the debugger connected. I suggest you to connect more earlier or look at your code flow, generally hang causes from peripherial device access.
