I proceeded with the analysis.This happens right after the PE task has finished.I suspect that this is the trouble with the I2C peripherals' exclusive control.After the cable detaches, the Alart task terminates the PE task. If the PE task is in the m...

Hi YohannI found the cause of the problem.The power supply was the cause.As soon as I unplugged it, the DCDC converter on the 5V line was outputting an overvoltage.This would cause the DC converter on the 3.3V line to be temporarily disabled.Maybe ...
