Hi, I've configured interrupt for gpt channel 0 (continuous mode) in eb tresos without os isr and the interrupt is executing only once i've checked for the registers after starting the timer of gpt TIE bit of cputimer register0 is 1 but after one interrupt it is getting 0 i checked for disable interrupt func call also no where it is executing after gpt start timer,
i've attached the main.c
#define APP_GPT_CH0_INT_ID (6U)
#define APP_INT_PRIORITY_DEFAULT (255U)
#define APP_INT_THRESHOLD (20U)
#define APP_PIPE_LINK_OWNER (2U)
