nRF9160-DK interface MCU extreme heating and generates error 33 when flashing

[GPO]

Hi Everyone,

My issue is mostly stated in the subject, I hope someone can help me recover this DK because as of the moment this is my only way to program/debug out EVT board for our current product, thank you in advance.

Thanks for providing this information. 

Has the EVT board been through HW review by any of our engineers? Please provide HW schematics, and an overview of how the two boards are connected.

Are you seeing this issue if the EVT is not powered by battery? What kind of output does the battery charging circuit provide? 

Will discuss with our HW guys.

Kind regards,
Øyvind

If no external board connected, does the interface MCU get as hot?
