KCU105 Board FMCH VADJ Adjustment
The KCU105 board system controller must apply power to the VADJ power rail for the HDMI 2.0 FMC card (TB-FMCH-HDMI4K). Most new boards are per-programmed and should be detected. The VADJ is powered when the DS19 LED (located near the power switch on the KCU105 board) is ON.
If an older version KCU105 board is used, or the board is not properly programmed upon receiving, you must manually set the VADJ power rail to 1.8V for the HDMI 2.0 FMC card prior to bitstream configuration.
KCU105板FMCH VADJ调整
KCU105板系统控制器必须为HDMI 2.0 FMC卡（TB-FMCH-HDMI4K）的VADJ电源轨通电。大多数新电路板都是按程序设计的，应进行检测。当DS19 LED（位于KCU105板上的电源开关附近）亮起时，VADJ通电。
如果使用较旧版本的KCU105板，或者板在接收时未正确编程，则必须在比特流配置之前手动将HDMI 2.0 FMC卡的VADJ电源轨设置为1.8V。
Perform these steps to set the VADJ power rail through the UART terminal are:
1. Connect a USB cable between the USB UART connector of the KCU105 board and a PC running Windows.
2. Use the Windows Device Manager to determine which virtual COM port is assigned to the UART for the Zynq-7000 AP SoC system controller and which is assigned to the UART for the UltraScale FPGA. In the list of COM ports in the Device Manager window, the enhanced COM port associated with the CP210x, is the one connected to the KCU105 board system controller and the standard COM port is the one connected to the FPGA UART.
执行以下步骤，通过UART终端设置VADJ电源轨：
1.在KCU105板的USB UART连接器和运行Windows的PC之间连接USB电缆。
2.使用Windows设备管理器确定哪个虚拟COM端口分配给Zynq-7000 AP SoC系统控制器的UART，哪个分配给UltraScale FPGA的UART。在设备管理器窗口的COM端口列表中，与CP210x关联的增强COM端口是连接到KCU105板系统控制器的端口，标准COM端口是与FPGA UART连接的端口。
3. Open a terminal window (115200, 8, N, 1) and set the COM port to the one communicating with the KCU105 board system controller.
4. After the UART terminal is connected, power cycle the KCU105 board to refresh the system controller menu in the UART terminal. Select this option in the system controller menu:
a. Adjust FPGA Mezzanine Card (FMC) Settings.
5. In the next menu, select:
a. Set FMC VADJ to 1.8V.
3.打开终端窗口（115200，8，N，1），将COM端口设置为与KCU105板系统控制器通信的端口。
4.连接UART终端后，重启KCU105板，刷新UART终端中的系统控制器菜单。在系统控制器菜单中选择此选项：
a、 调整FPGA夹层卡（FMC）设置。
5.在下一个菜单中，选择：
a、 将FMC VADJ设置为1.8伏。
Migration Notes
When migrating from version 2016.3 or earlier, make note of the following:
• Hot Plug Detect Active has been added to HDMI 1.4/2.0 Transmitter Subsystem GUI.
Choose High in the Example Design (according to board design).
• Hot Plug Detect Active has been added to HDMI 1.4/2.0 Receiver Subsystem GUI.
Choose Low in Example Design (according to board design).
• Cable Detect Active has been added to HDMI 1.4/2.0 Receiver Subsystem GUI.
Choose Low in Example Design (according to board design).
• HDCP 1.4/2.2 is enabled by default in Example Design application software.
Removed UART option to Enable HDCP 1.4 or HDCP 2.2.
• Auto switching has been added to the Example Design Application software.
You do not need to choose HDCP 1.4 or HDCP 2.2 from UART. A corresponding HDCP is selected according to the capability of connected source/sink. If the device support both HDCP 1.4 and HDCP 2.2, the priority is given to HDCP 2.2.
• HDCP repeater feature has been added.
You can enabled/disable it by selecting “h” from UART menu.
• System log is moved from direct UART printout to event log.
You can display the event log by selecting “z” from UART menu.
迁移说明
从版本2016.3或更早版本迁移时，请注意以下事项：
•热插拔检测激活已添加到HDMI 1.4/2.0发射机子系统GUI。
在示例设计中选择High（根据电路板设计）。
•热插拔检测激活已添加到HDMI 1.4/2.0接收器子系统GUI。
在示例设计中选择Low（根据电路板设计）。
•HDMI 1.4/2.0接收器子系统GUI中增加了电缆检测激活功能。
在示例设计中选择Low（根据电路板设计）。
•默认情况下，在Example Design应用软件中启用HDCP 1.4/2.2。
删除UART选项以启用HDCP 1.4或HDCP 2.2。
•自动切换已添加到示例设计应用软件中。
您不需要从UART中选择HDCP 1.4或HDCP 2.2。根据连接的源/汇的容量选择相应的HDCP。如果设备同时支持HDCP 1.4和HDCP 2.2，则优先考虑HDCP 2.2。
•增加了HDCP中继器功能。
您可以通过从UART菜单中选择“h”来启用/禁用它。
•系统日志从直接UART打印输出移到事件日志。
您可以通过从UART菜单中选择“z”来显示事件日志。
