GENERAL
The Mega128-Net development board is designed for prototyping, laboratory and OEM
use. The board hosts an ATMega128 processor along with 10baseT Ethernet, two RS232
ports, a Real-Time-Clock, 32K of SRAM, an Optrex® compatible LCD connector, four
R/C servo connections, JTAG and ISP ports, an MMC/SD slot, two 8-bit memory accessed
parallel output ports, two 8-bit memory accessed parallel input ports, and a fully decoded
expansion bus connection.
Mega128 AVR® Boot Loader
The Mega128-Net development board now comes programmed with the AVRBL-128,
Mega128 AVR Boot Loader. The AVR Boot Loader (AVRBL) is a bootstrap loader that,
once programmed into the AVR boot-block memory area, allows reprogramming of AVR
microcontrollers without need for a chip programmer. The AVRBL makes use of the self-
programming features of the AVR microcontrollers to allow in-circuit reprogramming.
Once the AVRBL is programmed into the microcontroller, it remains resident until the chip
