Other Parts Discussed in Thread: EK-TM4C1294XL
Hello all,
We use the TM4C123AH6PM for about 8 years to produce our boards, on about 3000 mounted boards.
In a new project I encountered the following problem:
Sometimes when you power on the system the processor stops working, the quartz does not run, and no debug possibility.
I tried to perform a factory reset with LM Flas Programmer but it still doesn't work, and all I can do is to replace the micro.
All voltages are correct, but I have noticed that a frequency of 14.7Hz comes out of the TDO signal.
Does anyone know what an output frequency from the TDO means?
Thanks.
