Set up the hardware

Before you can work with the board, here are a few things you must do. You'll need to set up the Phytec phyBOARD NASH. For more information, see the Quick Start Guide at https://download.phytec.de/Products/phyCORE-iMX93/Quickstart/Quickstart_phyBOARD-Nash_iMX93_L1071eA0.pdf on the Phytec website. The following is an overview of how to set up the phyBOARD-NASH.

Connect the hardware

CAUTION:

Use only the DC power supply provided with the board. Use of any other power supply may permanently damage the board.

  1. Connect the USB Debug port X37 to the USB port on your host computer with the USB type A to type-C cable.
  2. Connect the Ethernet cable to the Ethernet Connector X10 on the board.
  3. Connect the provided DC power supply to the board.
  4. Press the SW2 Reset switch on the board to restart.
  5. On a Linux host, you can check which port is the host serial port by looking at what port appears when the cable is inserted. To do this, type the command: 
    $ ls /dev/ttyUSB*

    On a Windows system, open the Device Manager and expand the Ports (COM and LPT) section. Then, look for a COM port named Gadget Serial or USB Serial Port. The connection is physically made via the Type-C from the board to your host computer. You must also have installed the COM Port (VCP) Driver (see the Before You Begin chapter in this guide).

  6. Connect to the COM port using your favorite terminal program with these settings. :
    • Baud rate: 115200
    • Data: 8 bit
    • Parity: none
    • Stop: 1 bit
    • Flow control: none

Set DIP switches on the phyBOARD-NASH

While booting the board, U-boot is loaded from the MMC i.e. microSD card, so keep the boot select switch to boot from microSD card position. On the phyBOARD-NASH, the boot select switch is SW3.
