If it helps, the BSP method the code is stuck in (infinite while loop) is "__pe_initialize_hardware()". The description is: "Initializes the whole system like timing, external bus, etc. This method is internal. It is used by Processor Expert only.". So, obviously, I'm treading on very thin ice here. I tried commenting out the while loop. But the code contains several such loops and execution gets stuck in a similar while loop several lines down. Here's the code segment of this method:
/* MCG_C11: PLLCLKEN1=1 */
MCG_C11 |= (uint8_t)0x40U; /* Enable the PLL */
/* MCG_C12: LOLIE1=0,??=0,CME2=0,VDIV1=8 */
MCG_C12 = (uint8_t)0x08U;
while((MCG_S & MCG_S_IREFST_MASK) != 0x00U) { /* Check that the source of the FLL reference clock is the external reference clock. */
}
while((MCG_S & 0x0CU) != 0x08U) { /* Wait until external reference clock is selected as MCG output */ <===GETTING STUCK HERE!!!
}
/* Switch to PBE Mode */
/* MCG_C6: LOLIE0=0,PLLS=1,CME0=0,VDIV0=8 */
MCG_C6 = (uint8_t)0x48U;
while((MCG_S & 0x0CU) != 0x08U) { /* Wait until external reference clock is selected as MCG output */
}
while((MCG_S & MCG_S_LOCK0_MASK) == 0x00U) { /* Wait until PLL locked */
}
/* Switch to PEE Mode */
/* MCG_C1: CLKS=0,FRDIV=5,IREFS=0,IRCLKEN=0,IREFSTEN=0 */
MCG_C1 = (uint8_t)0x28U;
while((MCG_S & 0x0CU) != 0x0CU) { /* Wait until output of the PLL is selected */
}
-thanks
