I added image into core1 refer to example of kw47loc_hello_world_primary_core.

But kStatus_HAL_RpmsgTimeout still happened on debug, because no callback of RPMsgPeerReadyEventHandler, the event data not change.
call step:
APP_InitBle -> PLATFORM_InitBle -> PLATFORM_InitMulticore -> HAL_RpmsgMcmgrInit -> HAL_RpmsgMcmgrMasterInit
-> MCMGR_Init -> MCMGR_RegisterEvent -> MCMGR_StartCore, after time out ASSERT happen.
Could you help us? Thank you so much.
