DE10-Advance Hardware Manual revC Chapter9 known issues
From Terasic Wiki
1. HDMI and HPS Ethernet Port
Cannot use both HDMI and HPS Ethernet Port at the same time. This issue will be resolved in RevD
2. USB Type C Power與 USB Serial Device
當使用USB Type C Power給DE10-Advanced供電前, 先請勿用USB Cable將電腦與USB Serial Device連接, 否則會出現開機不正常現象. 需等DE10-Advanced開機正常後, 再連接 USB Serial Device . 此問題將會在RevD解決
