CCS/TM4C123GH6PM: All interrupts doesn't work while debugging

VITALI HARUDKA

Part Number: TM4C123GH6PM
Other Parts Discussed in Thread: EK-TM4C1294XL, SEGGER,

Tool/software: Code Composer Studio

Hello. I have a custom board with TM4C123GH6PM MCU. I use segger for debuging. Then i start debug my code no one interrupts doesn't happend(periodic timer). But if i repower contorller it work correctly. I checked it by toggling led in different interrupt handelrs. I am sure about added IntMasterEnable(); line in my code after initialization. Before using my custom board i used ek-tm4c1294xl for practice and similar code work great(i just changed pinmux). How to fix it?

I am not familiar with the Segger debugger, but the TI debugger (Code Composer Studio) has options for disabling interrupts when either assembly stepping or C source code stepping. By default in Code Composer interrupts are disabled in assembly stepping only. You might want to enquire with Segger if they have a similar option.
