TX MIPI-LVDS StarterKit

This guide will help new users to quickly set up our TX MIPI-LVDS Linux Development Kit.

Detailed information about the TX modules are available at https://www.karo-electronics.com/products .

Unboxing

When opening the package of the Development Kit you should find the following components inside:

  1. Our catalog and the TX datasheet.

Assembling and Connecting

Assemble and connect the board to the display as shown in the following pictures. This means:

  1. Connect the display powering between board power outlet and displays power input.

  2. Connect the touchscreen to USB cable between the displays port and the USB-host port of the board.

  3. Carefully connect the display signal cable.

  4. Place the display on the stand and place the board in front of it.

  5. As the last step connect the 12V DC power and plug the AC adapter into your powerline.

Warning

Please be careful, it’s highly recommended to disconnect the 12V power before (un)plugging the module or other cables.

Hint

When you have the TX8M-ND00 module, you will have to use the micro-USB to USB adapter to connect the touchscreen. The second USB-host is not working with the i.MX8M Nano processor.

Re-installing the OS

  • The pre-compiled image files to flash the TX8 Development Kit are located in our Download Area.

  • They contain different environments, e.g. a minimal and a desktop environment.

  • Download the images and proceed with the UUU - Universal Update Utility.

CAN support

If you want to use a CAN interface via the Raspberry Pi-Connector on the TX-MIPI-LVDS, you have to enable CAN inside the compiled .dtb.

With using this DTB, the CAN interface via SPI gets activated for you, and you should be able to set up the device as an interface.

Notice the placing of the CAN interface: For an exact pinout see the X11 Header in TX-MIPI-LVDS Mainboard Pinout.
