when debug the demo project " frdmk64f_demo_apps_lwip_lwip_httpsrv_freertos "
if set a break point or suspend, it will error show as picture
for other project is OK, what shall I do?
Not sure, but I would remove all breakpoints, maybe this helps?
I have tried, but it does not work
What about the step debug ? Please use the Quickstart Panel to have a try :
And you'd better change to another new workspace .
I have test on my side, it can work well, if still can't work well, please take screenshots about the steps you do.
In addition, please be sure to attach the debug log from your debug session. The scheme to capture this is the same as shown in the FAQ below:
