As soon as I entered power down mode without any method of waking the board up, I cannot enter the debug more anymore. How can I solve this?

my code as follow:


int main(void)
{
  SystemCoreClockUpdate();
  Board_Init();
  SysTick_Config(SystemCoreClock / TICKRATE_HZ);
  ProcessPowerState(PMU_MCU_POWER_DOWN);

}

Hello Victor,

I tried the given solutions in the above link but none worked for me.

I am using LPC54618 MCU and LPCXpresso IDE.

Is there some other way to come out of this problem?

regards,

SS

Hello Lee Chen, 

Did  you put your MCU in ISP mode following the steps mentioned in the community post I put before? Once you are in ISP mode you should be able to launch the debug session without any problem. 

Also, I recommend you to use MCUXpresso IDE since in our newest IDE instead of LPCXpresso.

Hello Victor,

Yes it worked.

LPC54618 has three ISP pins so I connect it to GND and followed the instruction mentioned in this https://community.nxp.com/thread/389112 .

Thank you.

regards,

SS

Hello Lee Chen, 

Please refer the following community post: Regaining debug access to target MCU 

You need to recover the debug access to the MCU. That community post explains how to do this. 

Hope it helps! 

Victor.
