Set all MSEL switches to "1" by mistake
From Terasic Wiki
Q：If you set all the MSEL switches (SW10) to "1" by mistake, why is the SoC incredibly hot after powering on the DE10-Nano board?
A:This is because the device would be a invalid state when all switches to "1", this would cause device high power and lead to incredibly hot.
So, customers need follow our user manual to use the DE10-Nano board, take care of the MSEL settings and do not set all the MSEL switches (sw10) to "1" .
