I use HCS08 QE4 MCU along with OpenSource BDM. Suddenly I can't connect to MCU (I'm not aware that I did something wrong with my board where the MCU is at the time the problem appeared).
The program that is loaded in MCU is running correctly
I caught some waveforms. When I connect MCU to OpenSource BDM the waveforms are deformed:
(voltage between GND and 3.3V appears on the line, edges of signal are not steep)
When I disconnect MCU the output signal of OpenSource seems not to be deformed.
Is there anything you can advise to me?
