Hi, I’m seeing an issue with MISO high voltage. The MISO is measured at 1.45V (1.8V is the intended design). The MISO is connected to a level translator that translates 3.3V to 1.8V. The MISO on the 3.3V side shows the correct waveform. And all other SPI lines are correct at 1.8V. What can be causing this pull down by Jetson during the active state?
The scope capture shows the 1.45V abnormal waveform (top) and the 3.3V side of the level translator (bottom).
