TM4C1294NCPDT: TM4C1294NCPDT

Ramesh Muruganantham

Part Number: TM4C1294NCPDT

In one of the custom built board based TM4c1294NCPDT, the crystal is not oscillating in a newly assembled board. We changed all the components (crystal, capacitor, resistor) except microcontroller. But the there is no clock from 25Mhz crystal. Is it that TM4c1294NCPDT gone bad?

Hi,

What if you do a ABA swap test? Swap out the MCU to a good know board. Will the problem follow to the good board?

It is difficult to remove the MCU without damaging. So we will try to replace another MCU and let you know
