8.4 Compute Module menu
Service Menu
USB Boot Mode
Available options: Enable / Disable
When set to
Enable
, the Compute Module will appear as a USB device to a PC connected to the USB2
input on the display and can be programmed with an Operating System. When set to
Disable
, the
Compute Module will boot normally. See chapter USB connections for programming the Compute Module
on page 15.
8.5 Compute Module menu
Service Menu
IR Signal
Available options: Enable / Disable
Enables or disables the forwarding of IR remote control signals, received from the display’s internal and
optional external IR sensor, to the Compute Module via GPIO 18.
See section 0 for more details on using this feature.
8.6 Compute Module menu
Service Menu
Monitor Control
Available options: Enable / Disable
Enables or disables the internal serial connection between the display and Compute Module. If set to
Enable
, communications is available via GPIO 14 & 15. This GPIO will normally appear as a TTY device.
Make sure the Operating System doesn’t send boot console debug messages to the UART serial port; it
may cause erratic behavior in the display (such as the OSD flashing, random operations being performed,
slow bootup of the Compute Module, etc.).
