BLE程序不能下载

Good day Dialog,

I want to consult my current problem with DA 14580

I have succeed on downloading blinky, timer on my Custom Board using Keil.

But when I try to download ble_app_peripheral , program can't be burn into my DA

I only be able to debug my IC, but the program can't be burned into it.

Error always happen on this line :

Tab : hardfault_handler.c

if ((GetWord16(SYS_STAT_REG) & DBG_IS_UP) == DBG_IS_UP)
__asm("BKPT #0\n");
else
while(1);
}

What is the meaning of this line of the program? This problem always pop out, and I don't find a way to overcome this problem.
Can you give me insight what to be done?

Kinds Regard,

Christian Laksmono
