Target marked as not debuggable

Hi everyone,

at some point my NHS3152 demo board started to refuse being programmed. I cannot say that I did anything extraordinary at all, it simply stoppped working.

This is the error message I get every time I try to debug my program via LPCXpresso:

LPCXpresso RedlinkMulti Driver v8.2 (Sep 5 2016 10:12:38 - crt_emu_cm_redlink build 725)

What could possibly be the problem? I checked and exchanged all the cabling and even exchanged the LPCLink programming board.

Any help with this would be greatly appreciated.
Thanks in advance!

Best regards

Lukas

Hello,

First, confirm whether the battery power of the board is sufficient.

Secondly, when the board is connected through LPC- jink2. Does Flashmagic have a normal interface as the picture 1?

And please find the result of the test as the picture2(make sure your setting of LPC-JINK2 as the picture ).

Have a nice day.

Hi fangfang,

thank you very much for your answer. I checked all the things you mentioned and also again exchanged cabling etc. Still, flashing fails. FlashMagic shows this error message:

The LPC Link 2 board does appear in device manager.

Sometimes also this error occurres when trying to use FlashMagic:

What could possibly be the problem? Thanks again

Hello,

It seems the lpc-link2 doesn't work. You may try MCU-Link Pro as the link.

Have a nice day.
