I am trying to debug the dfu bootloader using SES. This is my first time using SES. I opened the example project and everything builds fine. The image loads on the device and appears to run ok, but when I pause the debugger, the IDE only shows the current position in the disassembly window. Even if I have the source open, it does not show where it is. Additionally, when I try to add a breakpoint in the source, it shows a red dot with a ? in it. Any idea what I am doing wrong?
