I've done some searching on the forum, and this question seems to be asked, but no concrete answer has been given. I'm using the Tiva C with the latest uVision. I have a main.s where all my assembly code is located. When I try to debug, it steps through my startup file, but when it branches to my asm file, it will not jump to it. Even when I set breakpoints in the main.s, it only shows the line in the disassemly window. Thanks for your help!
