RTOS/CC2642R: Not able debug the TI-RTOS Project , it is not jumping to main function from internal ROM area, with Evolution board it is working fine.

Adding to previous post , here with i am putting some more input related the issue.
while debugging project with TI-RTOS API's we are getting the below fault exception message and unable the debug the code.

" Hard Fault Exception:
The processor has escalated a configurable-priority exception to HardFault.
An imprecise data access error has occurred (CFSR.IMPRECISERR, BFAR).
Exception occured at PC = 0x1003b770, LR = 0x169d"

Call Stack Message:
"[ti_sysbios_family_arm_m3_Hwi_return + 0x3] "

One more observation regarding custom build:

When we add below changes in TI-RTOS.cfg file

var ROM = xdc.useModule('ti.sysbios.rom.ROM');
if (Program.cpu.deviceName.match(/CC2640R2F/)) {
ROM.romName = ROM.CC2640R2F;
}
else if (Program.cpu.deviceName.match(/CC26.2/)) {
ROM.romName = ROM.CC26X2;
}
else if (Program.cpu.deviceName.match(/CC13.2/)) {
ROM.romName = ROM.CC13X2;
}
else if (Program.cpu.deviceName.match(/CC26/)) {
ROM.romName = ROM.CC2650;
}
else if (Program.cpu.deviceName.match(/CC13/)) {
ROM.romName = ROM.CC1350;
}

Prebuild option is failing. Is that any other changes required when we add this change in .cfg file.
