    Hi Fabian, VTRef is not having and difference as it is derived out using a buck and used onboard for other functions as well. Regards Raj Nikumbh

    Hi Fabian, I am sorry, maybe my explanation was not correct. The overshoot is being observed on the Clock line. Hence I was suspecting that Jlink is adding something here on when the power supply is 3.3V Regards Raj Nikumbh

    Hi Fabian, Thanks for your reply. These are two different custom PCBA that we have made. The power to the MCU is generated using onboard buck regulators. Jlink is connected using a cable of about 250mm. The setup remains similar for both 1.8V and 3.3V…

    Hello, We are using Jlink for flashing and debugging on two different MCU's from NXP. One has a working voltage of 3.3V while other has working voltage of 1.8V. There is a considerable overshoot seen on 3.3V system of about 850mV which is much beyond…
