Info Box Applies to Lizard Applies to LizardEVB-Lite

IntroductionEdit

LizardEVB-Lite is a development/test board designed to start working with the Lizard SOM and experimenting with the implemented features.

The following picture shows block diagram of NaonEVB-Lite board.

Quick start (LELK)Edit

This section describes how to quick start Lizard-EVB-based system, provided that it is programmed according to LELK configuration.

1. to power the board, connect ATX power supply to connector JP10
2. connect DB9 P2 connector to PC COM port through a straight serial cable
3. start your favourite terminal software on PC; communication parameters are:
   • baud rate: 115200 Bps
   • data bits: 8
   • stop bits: 1
   • parity: none
4. (optional) to connect the system to Ethernet LAN, please plug cable on connector JPF1.

Once power has been applied, U-Boot bootloader will be executed and the following messages will be printed on serial console:

U-Boot 2009.11 (Jul 20 2010 - 16:44:20) [lizard-1.2.3]
AM35xx-GP ES1.0, L3-165MHz

Please note that you need to modify some u-boot environment variables before running the net_nfs configuration. For further information, please refer to Configuration net_nfs.

Hardware informationEdit

Bootstrap settingsEdit

JTAG interfacesEdit

JP2 connector makes available JTAG signals of the microprocessor in order to connect a JTAG Hardware Interface. Signals are pulled up internally to Lizard module with a 10K resistor.
