I have found debugging in the latest Momentics IDE (QNX7.04) a bit of a hit or miss affair. When it works it’s pretty good.
My main problem is similar to yours - only I can see the source code and set breakpoints. Only no break occurs - on execution it sails on through as though there were no breakpoints (except for the program start).
There doesn’t seem to be much in the way of debugger driving instruction (same for the profiler and other interesting goodies that come with this package). In fact there doesn;t seem to be much useful material for the IDE generally at all. Maybe I’m just not looking hard enough!
So, I am back to how Tim debugs (and others I know of) : printf() is and has always been my friend.
But I would sure like to master the IDE debugger as it does seem to tantilisingly show a lot of potential.
I will take another look at it maybe this afternoon and see if I can make it or break it - and maybe see if I can make it behave the way it is for you (in the video).
FYI I am using Momentics mainly with a Xilinx SoC (ARM A53 64-bit) but do have both real and virtual x86_64 systems if I need them. I don’t think the debugger really cares what the target platform might be.
