Core Power Down Issue

schougule01 — Tue, 14 Mar 2023 05:26:47 GMT

I am facing issue while loading script in the debugger.

I am getting "Core Power Down" issue while try to load script.

Is there any way to turn ON the Core Power to UP.

Controller: S32K148

Hi @schougule01,

If the MCU powered, can you measure the VDD?

Can you please share the script?

Thanks,

BR, Daniel

Hi,

@danielmartynekactually there is no issue in script as it works for other hardware.

Hi @schougule01,

Do you mean it works with other S32K148 MCUs?

Since I can't reproduce it, I would like to test you script on my side.

Is the VDD powered?

This error message usually means that the core's power domain in the SoC is not enabled. If the whole SoC is not powered, the error message would be "target power down" and the debugger would usually display "power down" in the status bar.

Detection of "Core Power Down" is not 100% reliable, depending on the SoC it could simply mean "could not communicate with core", with disabled power domain being the most typical reason.

Hi @schougule01,

Can you catch it right after POR?

system.CPU S32K148 wait state.power() system.attach
