Document Table of Contents Modifying the UART Port Number for Serial Terminal Messages

The Intel® Arria® 10 SoC FPGA development board is uses UART1 for the serial terminal messages. If your custom board uses UART0 instead of UART1, you must change the UART base address so that your output messages display on the correct UART port.
  1. Use your preferred editor to open the <your_uefi_socfpga>/uefi-socfpga/AlteraPlatformPkg/Arria10SoCPkg/Arria10SoCPkg.dsc file.
  2. Configure the gEfiMdeModulePkgTokenSpaceGuid.PcdSerialRegisterBase value from 0xFFC02100 to 0xFFC02000.

  3. If you want to boot faster and do not want to see any output messages in the serial terminal, configure the gEfiMdeModulePkgTokenSpaceGuid.PcdSerialRegisterBase value to 0x0.
