...
- phyBOARD-Segin Kit (PB-02013) (or another suitable phyBOARD Kit)
- PEB-AV-02 LCD Display Adapter for Glyn Displays
- 40 pin FFC flex flat cable (PHYTEC Part # WF061)
- 7'' EDT Display (PHYTEC Part # AC104)
- AC power supply 12 V – 24 V DC/ min. 2.5 A
- Serial Cable - RS232 (not pictured)

Connect the host PC and phyBOARD-Segin assembly with the serial cable (use UART0 on PEB-EVAL-01 board) and insert power connector into mating connector as seen below.
Modifying the expansion board configuration file
...
The BSP is preconfigured to support various expansion boards, including the 7" display, and simply need to be enabled for use. Apply power to the device and monitor the serial output. When prompted, stop auto-boot by sending a character in the serial terminal.
At the u-boot Barebox prompt, modify the config-expansions file with the command below:
| Code Block | ||
|---|---|---|
