I recently started working with NXP Kinetis processor and I ran in to a problem with FreeMaster debugging tool.
I followed the tutorial here : https://mcuoneclipse.com/2013/08/24/tutorial-freemaster-visualization-and-run-time-debugging/
but I cannot get it to work.
The following error shows up in FreeMaster tool after I try to connect : "Can not detect the board information. The communication will be paused."
It worked one time (I don't know what I did), but then I added another variable to the project so that I can control it (as in tutorial) and it again stopped working.
If anyone is interested:
The problem occurred when I was reading a register that I shouldn't have. It caused the processor to go into Hard_Fault interrupt where it stoped.
It then couldn't maintain the connection to the FreeMaster as it should call the FMSTR1_Poll() function regulary.
