I have a project that used to work. I made a whole bunch of edits to it and now it looks broken. It's so frustruating: I put in a whole bunch of printfs to test where the source of error is. I find a point where I write printf("%d %f %d\n", rowNo, a, b); and it works. Then I do a printf("%d\n", b) to check and it gets stuck on the unknown exception occurred, do not know what to do error. Anything else that I try to print after the first printf("%d %f %d\n", rowNo, a, b); will give the error. The EXCAUSE is 2B which is the Instruction fetch CPLB protection violation...illegal instruction fetch access (memory protection violation.) I don't know what to do after that... I checked out the sequencer to find where it last stopped, but I don't know assembly so I haven't the smallest idea what is wrong. Please help!
