Hi, Can you list out the steps followed to see this error ? [quote userid="458998" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1551211/f29h850tu-nmi-interrupt-hit-when-sysctl_delay-function-is-run-for-f29h85x"]I see my code gets stuck at Sysctl_Delay() function[/quote] What do you mean by code gets stuck ? There is nothing in delay function that can cause issue its probably the steps done before or after that causes the error. When it goes to NMI ISR can you get the error aggregator registers using Scripts menu as shown below If using default NMI ISR make sure CPU1 code stays at ESTOP when using scripts menu. More guidance on how to debug the error follow the steps pointed out in thread here - F29H850TU: How to analyze the specific cause and type of ESM error triggering NMI interrupt Thanks
