A headless setup is possible, though in the Quickstart Guide we will always assume that you have a recommended display attached to the carrier board. If you proceed without a display, skip the lessons that make use of it at your own discretion. As an option, you can follow the Torizon Documentation - just be aware you will not find a walkthrough as thorough as this guide.
Step 1
Remove the Dahlia Carrier Board and the Verdin Computer on Module from the blisters. Insert the computer on module into the X1 connector of the carrier board as tight as possible, with the module inclined ~30 to 45 degrees in relation to the carrier board.
Make sure that the module is well connected to the carrier board. The image below has some checkpoints highlighted.
Step 2
Connect the DSI to HDMI adapter to the X17 connector of the carrier board. Fixate it by screwing the four included screws.
Step 3 (Optional)
Screw the Verdin Industrial Heatsink on top of the SoM, using the screws that come with it:
Step 4
- Connect an HDMI display to the DSI to HDMI adapter.
- Connect a USB keyboard/mouse to the Dahlia's X4 connector.
- Connect the Ethernet cable to the Dahlia's X11 connector.
- Connect the USB Debug to the Dahlia's X18 connector.
Ethernet network must provide DHCP and Internet to the module.
- Connect the power supply to the Dahlia's barrel jack X9.
Double check that your power supply is within the Dahlia Carrier Board limits (5-24V) and that the polarity is not inverted. Also, make sure that the current capability of the power supply is enough, or the system may shut down unexpectedly. For evaluation purposes, a 12V 2A power supply is recommended.
