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)
This section describes how to quick start Lizard-EVB-based system, provided that it is programmed according to LELK configuration.
- to power the board, connect ATX power supply to connector JP10
- connect DB9 P2 connector to PC COM port through a straight serial cable
- start your favourite terminal software on PC; communication parameters are:
- baud rate: 115200 Bps
- data bits: 8
- stop bits: 1
- parity: none
- (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 DAVE Lizard board + LPDDR/NAND I2C: ready DRAM: 256 MB Flash: 128 MB NAND: 1024 MiB In: serial Out: serial Err: serial Die ID #6d3600000000000001543b2102017026 Net: davinci_emac_initialize Ethernet PHY: GENERIC @ 0x10 DaVinci EMAC =>
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.
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.
