RT1170 EVKB Multicore project and LinkServer Flash programmer not working (mcuxpresso vs code)

[cyberhelmer]

I have a project based on the freeRTOS multicore message buffers example from nxp SDK. 
There seem to be a problem with the LinkServer Flash Programmer in the mcuxpresso for vs code extension.

I am sometimes able to flash the m7 firmware which loads the M4 to the correct ocram adress. Very often the flash programmer fails and the board stops running it's code. 

What is the cause of this and how can I fix it so that I'm always able to flash the m7 correctly? 

Thanks!

Also, sometimes when I make changes to both cores and do a clean and rebuild of both projects only the m7 is updated with the correct code, m4 still runs an older version.

Hi @cyberhelmer ,

Thanks for  your interest in NXP MIMXRT series!

During the failed operation, I noticed it was missing from the logs:

Releasing M4

This led to subsequent failures. We recommend updating the MCU-Link firmware and performing the following operation when debugging or programming again:

On the other hand, based on my personal experience, using JLink firmware provides better stability. If possible, try replacing the MCU-Link firmware with JLink firmware.

Best regards,
Gavin

[cyberhelmer]

I do have have latest firmware for the MCU-Link. 

Resetting the probe before a flash as you suggested does not make a difference unfortunately. Still get this error most of the time:

Also I've noticed that when when the flashing actually succeeds the M4 core is most of the time one or more versions behind even though I do a clean and rebuild of both projects before flashing. However sometimes, seemingly randomly both cores does get the correct version. 

This is the build log:

What could be causing this?

I will try J-link firmware and see if that helps.
