Introduction

Ka‑Ro Starterkits are ready-to-use development systems for building applications based on the Ka‑Ro TX Computer on Modules.

Package Contents

  • TX6UL Mainboard
  • 9 pin serial communication cable adapter
  • USB cable

General Precautions

Take note of the following general precautions before you begin working with the Starterkit Hardware:

Unplug the power cord from the wall socket before touching any component.

  • Use a grounded wrist strap or touch a safely grounded object, such as the metal.
  • power supply case before handling components to avoid damaging them due to electrostatic discharge.
  • Hold components by the edges and do not touch the ICs on them.
  • Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

Power Supply

Connect the Micro USB Port of the Evalkit to a USB port of your host PC.
Optionally a 5V DC power supply can be connected to the power jack

Module Replacement

The TX processor module is plugged into the socket of the starter kit base board. If it is necessary to remove the processor module from the socket unlock the module from the socket by pulling the two locking clips gently sideways away from the socket. If the clips are opened, the module flips into a diagonal position and can be removed.

If you insert the TX module into the socket again, the module should drop easily into place. Do not force the module into the socket to avoid damage to the socket. If the module does not fit check its alignment. You also may pull the two locking clips gently sideways away from the socket during insertion before the module is locked into the socket.

Ensure a good connection to the spring contacts on the bottom side of the module and that the clips are tightly locked in place!

Terminal connection

Use the supplied DB-9 cable to connect the Debug RS232 port to a communication port of your host PC, e. g. COM1. You need a terminal program like Windows Hyperterminal or Unix based minicom or cu, running on your host PC.

The default communication parameters used are (115200 8N1)

  • 115kbaud
  • 8 data bits
  • no parity
  • one stop bit
  • Xon/Xoff handshake.

Login

Linux is usually preinstalled on the module. Just wait until Linux has booted and log in as "root", depending on the rootfs with the optionally needed password "root"

Boot modes

A TX module provides two boot modes - boot from NAND/eMMC and serial boot via USB. The boot mode is selected by sampling state of the BOOT_MODE (TX-DIMM pin 8) on the rising edge of POR_B. The default boot mode is Boot From NAND/eMMC if the BOOT_MODE pin is left open. The serial boot is selected by driving the BOOT_MODE pin to 0V. The Serial Downloader provides a means to download a Program Image to the chip over USB serial connection.
