i've got a problem with the SAM3X8H on the SAM3X-EK. When i power on the EK the SAM3X8H getting hotter and hotter. I've already check the jumper configuration, everything is okay. When i drop of the VDDIO Jumper the chip cools down. So it seems to be a shortcircut on a peripheral pin, but i've got nothing connected to the EK. The first time i got this problem were after accessing the chip via SAM-ICE and programming an Atmel Studio Example.
