Hello, @DVais​:

 

Thank you for contacting Intel Embedded Community.

 

In order to better understand this situation, we want to address the following questions:

 

Could you please clarify if this situation happens on your design or a third- party design? 

 

In case that it is a third-party device, could you please inform the name of the manufacturer, its model, the part number, and where its documentation is stated?

 

On the other hand, could you please let us know how many units of the project related to this circumstance have been manufactured? How many are affected? Could you please give the failure rate? Also, could you please list the sources that you have used to design it and if it has been verified by Intel?

 

We are waiting for your reply to these questions.

 

Best regards,

@Mæcenas_INTEL​.
