Hi! I am getting started with multicore applications i using LPCXpresso4367. I found with MCUexpresso two examples - one is software for main M4 core, second is application for slave M0 core. I configured its according to:
https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/lpc/34158/3/LPC43xx%20Cortex-M4%20_%20M0...
but it not working - there is error " multiple definition of `main'" during build of main core project (multicore_mc_sa_blinky_m4) . Threre are two projects, so it must be two main functions. I tried to change name of main using pragma, no result.
Projects i found here:

Names of that projects are :
multicore_mc_sa_blinky_m0app
multicore_mc_sa_blinky_m4
My changes in propertis of [multicore_mc_sa_blinky_m4][ C/C++ Build][Setting][MCU Linker] - :
i selected M0APP as slave,
choosed Flash memory, and
selected file .o of slave application -blinky_m0.o
I missed something?
