Hello, We ordered the UDOO x86 Ultra and downloaded and installed Ubuntu 16.10 from the official site. We are having trouble accessing the UART ports on the Braswell board. From the documentation, it says we need an EFI BIOS to establish communication but, our version only installed a Legacy BIOS. Is there an official version that has the EFI BIOS included or is there another way to activate the UART ports? I've looked into the BIOS on startup and looked at the SATA ports where it shows the two UART ports as uninstalled. I have tried to change the boot BIOS to EFI instead of Duel w/ Priority or Legacy and I get kicked back to the BIOS screen to change the BIOS back to EFI or Duel. Thanks, Zack
