20 RabbitLink (EG2100)
3.2 RabbitLink Firmware
The firmware necessary to operate the RabbitLink with a Rabbit-based target system is
loaded at the factory. This means that after the hardware connections have been made and
the network parameters configured, the RabbitLink is ready to download a program to the
local or remote Rabbit-based system.
If it is necessary to reload or replace the firmware, the following .bin files are available
for download from the RabbitLink directory that was created when Dynamic C installed.
The .bin files are downloaded to the Rabbitlink using the RFU. The corresponding
source files are in the same directory and may be used instead by compiling them to the
RabbitLink using Dynamic C.
• CLEAR_PARAM.BIN—Binary image to reset the network configuration parameters of
the RabbitLink board (stored on the second flash) to default values. This binary file is
used to reset the serial port if its operation has become undefined.
• DOWNLOAD.BIN—RabbitLink firmware binary image.
The RabbitLink firmware version must be compatible with the version of Dynamic C that
is used to download applications to the target that is connected to the RabbitLink (see
Table 2). The companion CD in the RabbitLink Tool Kit contains versions 1.00, 2.00 and
2.05 of the firmware.
