Part Number: TDA4VM

Hi expert

my program working flow is:RBL bootload SBL,SBL boot load  mcu1_0 app(which should working on lock step mode)

base on SBL source code,“lock step mode” is setup base on image file context "MCU1_SMP_ID" by following calling tree:

SBL_MulticoreImageParse --> SBL_RprcImageParse(srcAddr, &entryPoint,(int32_t)(mHdrCore[i].core_id)) -->SBL_SetupCoreMem --> SBL_ConfigMcuLockStep(SBL_ENABLE_MCU_LOCKSTEP, sblSlaveCoreInfoPtr);

if mHdrCore[i].core_id == MCU1_SMP_ID),then mcu1_0 shall working on lock step mode

but now, it is not.

Question:

during making image file,how to set core_id to MCU1_SMP_ID?

Can you give me some detailed tips?
