Failed to boot second core on MCXN547

Hi NXP,

There is a question that needs your help.

IDE: MCUXpresso IDE V25.06

MCU: MCXN547VKL

Code project: modified from <frdmmcxn947_rpmsg_lite_pingpong> to match MCXN547VKL

Question:

After being builded, the master core can't slave core. I debugged the code and find that it will stop at MCMGR_StartCore() function, while it will work on FRDM-MCXN947.

Do you have some tips to us ?

Thanks.

Hi @jimmyli

I think you should download the SDK_XXXX_MCX-N5XX-EVK.

I have tested this example on my MCXN5XX_EVK board.

It can work.
