Hello,
While am trying to program MSP430FR2633, the VMAIE - Vacant Memory Interrupt Flag, and OFIE - Oscillator fault interrupt flag are enabled and the controller gets restart after sometime due to Watchdog timer.
Also it seems that program gets altered and it keep jumping at same memory location, not getting how to solve this error.
Kindly suggest any solution.
The screenshot for the same is shared below.
Hi,
As I can see from the code, you have disable the watchdog timer. Why it work, I adise you can see SYSRSTIV to check the reset source.
By the way, I check the assembly code, I can't find jump instruction.
Can you put your code with a smallest case, I can check it for you.
Eason
Hi Eason,
Thank you for response,
Herewith am sending you the code.
And about JMP instruction, it not there in CS_initClockSignal, but it gets edited automatically when controller gets restart.
Also VMAIE - Vacant Memory Interrupt Flag is enabled.

As I check, I can't run your code, so you need to debug it by yourself.
Can you use step over function, and don't enable VMAIE and OFIE to find after run which code,OFIFG or VMAIFG is set.
