hi guys,
In our design we use the TMS320F28069M cpu with the internal oscillator (X1 tied to GND).
3.3v and 1.9v are looking fine (ripple < 15mV).
After the startup the XRS Pin is every 14ms going down for 50us and repeating.
The cpu is not programmed at all.
We have two board with exact the same problem.
It seems like the same problem:

What can we do?
