RTOS/AM5746: Workaround the SMP project and compile switch

Part Number: AM5746
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Hi TI Experts,

Would you please confirm the following questions?

[Question.1]

This problem of link error in SMP mode with PDK. Since the following functions are only Undefined Symbol. 
ti_sysbios_family_arm_a15_Cache_wb__E
ti_sysbios_family_arm_a15_Cache_wbInv__E
ti_sysbios_family_arm_a15_Cache_inv__E

So, Customer prepared a wrapper to connect to smp/Cache.h like below. 
They will use this solution until you will modify this issue. How do you think?

[Solution]

//// main.cfg(cfg file) ///////////////////////////

// @@ for SMP add-S
BIOS.smpEnabled = true;
// Chose "true" or "false".
// ("false" = same as not set).
// @@ for SMP add-E

// @@ for SMP add-S

if (BIOS.smpEnabled) {
var Core = xdc.useModule('ti.sysbios.family.arm.a15.smp.Core');
Core.useSkernelCmd = false; /* Set to false if running in CCS and using gel files to wake-up secondary cores */
Core.numCores = 2;
var Cache = xdc.useModule('ti.sysbios.family.arm.a15.smp.Cache');

var SysStd = xdc.useModule('ti.sysbios.smp.SysStd');
var SysMin = xdc.useModule('ti.sysbios.smp.SysMin');
var LoggerBuf = xdc.useModule('ti.sysbios.smp.LoggerBuf');
} else {
var Core = xdc.useModule('ti.sysbios.hal.Core');
var Cache = xdc.useModule('ti.sysbios.family.arm.a15.Cache');
var SysStd = xdc.useModule('xdc.runtime.SysStd');
var SysMin = xdc.useModule('xdc.runtime.SysMin');
var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');
}
// @@ for SMP add-E

#define MP_MODE_SMP (2)

{
Cache_wb(blockPtr, byteCnt, type, wait);
}

Void ti_sysbios_family_arm_a15_Cache_wbInv__E(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait)
{
Cache_wbInv(blockPtr, byteCnt, type, wait);
}

{
Cache_inv(blockPtr, byteCnt, type, wait);
}
#endif //

[Question.2]
Is there a compile SW that can check the value of "BIOS.smpEnabled" ?

Best regards.
