1.3 Software
The RabbitLink board is shipped with firmware already installed in the flash memory. The rows in
the following table show which versions of Dynamic C and the RFU are compatible with which
versions of the RabbitLink firmware. The firmware version is the same as its serial console; the
version number is displayed in the console’s startup message.
1.3.1 Upgrading to Dynamic C 7.20
Z-World recommends upgrading to Dynamic C 7.20 as soon as possible. This requires upgrading
the firmware for older RabbitLink boards (boards shipped in the 2nd quarter of 2002 have
version 2.00 firmware). The simplified structure of the new RabbitLink firmware is more flexible
and is also more stable and robust.
Please see Section 3.2.1, “Downloading Firmware to the RabbitLink,” on page 13 for complete
instructions for downloading the firmware.
1.3.2 Remote Downloading and Debugging
Attaching the RabbitLink to the Ethernet and a Rabbit-based target allows a user to compile, run,
and debug programs on the remote board from a network-connected PC running Dynamic C 7.03
or later. All the standard features of Dynamic C are available over the remote interface, including
the Dynamic C
STDIO window, watch expressions, and the ability to step through C and assembly
code. Dynamic C can be used exactly the same way as it is for a board connected to the PC’s serial
port.
1.3.3 Passphrase Protection
Every time Dynamic C initiates a new RabbitLink session, the RabbitLink requests a passphrase
from the user to ensure the security of the programs and data on the remote boards. This pass-
phrase is stored by Dynamic C during that session so it only needs to be entered the first time
Dynamic C contacts the RabbitLink gateway. For security reasons, Dynamic C does not store the
passphrase on the hard disk of the PC.
