Identified core does not match configuration. (Found: Cortex-M0, Configured: Cortex-M4)

[karlin]

I have an LPC5410J256BD64QL that I am attempting to connect to with a J-Link Ultra+ for the purpose of flashing. However, I cannot connect to the device at all.

When I try to connect, I get the following error message in MCUXpresso:

The LPC5410 chip we are using has an M4 and does not have an M0.

I am able to debug with the J-Link debugger and step through code, so I believe the debugger is connected properly. In addition, at some point in the past I was able to flash the MCU but I had to change computers and now cannot get it working.

I am using the GUI Flash Tool in MCUXpresso to do the flashing. Here is a screen capture of the command that is being sent.

I am running MCUXpresso IDE v11.0.0 [Build 2516] [2019-06-05]. We are using a slightly older version of MCUXpresso for compatibility reasons, but I have also tried the most recent version v.11.2.1 and received the same output.

I have broken it down further by trying to connect to the chip using J-Link Commander and it is clear that I cannot connect to the chip. I received similar output.

I have checked reset pin 64 and it is being held high as it is supposed to be.

I have tried connecting to multiple chips, including hardware that has worked in the past.

Does anyone have a clue as to what might be going wrong? Any help would be greatly appreciated.

Further information. I enabled J-Link logging and captured the following while attempting to connect.

Hello,

Could you please retry with the latest version of J-Link software package?

Thank you for your response. I'm embarrassed to say that it was user error. We were connecting to the wrong debug header. All good now.
