Hi NXP,
In S32k358 ,I start from LpuartFlexio_Uart_Ip_Example_S32K358 ,
build download and power on reset ,it boot 5 times automatically,(normally boot only once)
How can i deal with this,Thanks !
my mian.c :
int main(void)
{
Clock_Ip_Init(&Clock_Ip_aClockConfig[0]);
Siul2_Port_Ip_Init(NUM_OF_CONFIGURED_PINS0,g_pin_mux_InitConfigArr0);
IntCtrl_Ip_Init(&IntCtrlConfig_0);
Lpuart_Uart_Ip_Init(LPUART_UART_IP_INSTANCE_USING_1, &Lpuart_Uart_Ip_xHwConfigPB_1_BOARD_INITPERIPHERALS);
IntCtrl_Ip_EnableIrq(LPUART1_IRQn);//uart1 for debug
IntCtrl_Ip_InstallHandler(LPUART1_IRQn, LPUART_UART_IP_1_IRQHandler, NULL_PTR);
Lpuart_Uart_Ip_SyncSend(LPUART_UART_IP_INSTANCE_USING_1, (const uint8 *)("welcome\n"), strlen("welcome\n"),100000u);
Mcu_ResetType boot_reason = MCU_NO_RESET_REASON;
boot_reason = Mcu_GetResetReason();
if((MCU_NO_RESET_REASON != boot_reason))
Bootloader_DebugPrint("\n Get Boot_Reason:0x%d\n",boot_reason);
while(1);
}
Hi @jimmy623,
The MC_RGM[FES] register points to an external reset.
Check the SBC or other devices that are connected to reset_b of the MCU on the PCB.

Hi danielmartynek,
In RM, mcu/pmic handshake by using PGOOD ,
If PGOOD assertion does not arrive within the configured time, POR WDOG will issue a reset to the MCU.
Can you show me how to enable PGOOD function in fs26.
Thanks!
