We use our own BF537 based board since 2Years. Everything works, but we observed some troubles on VDDINT Pin: more than 2V
if there is a defect/damaged FET transistor on a new produced board.
The DSP seems to be working correct. But would could be happen with the DSP if the supply voltage (VDDINT) is greater all the time.
We observed a greater temperature in this cases.
Is there an option to detect this(ideally in software?), now we check the current consumption in the board test routine.
