4 Development Environment Setup
A serial connection is necessary for communicating with your Bluetechnix Core Module.
Either a USB or a standard RS232 can be used. Please refer to the Bluetechnix Hardware User
Manual for the necessary base board switch settings.
To connect via USB cable, your operating system must have a device driver for the CP2101
USB‐to‐UART converter chip. Most pre‐compiled kernels of Linux distributions have it
already enabled. To verify this, power on your Bluetechnix board and connect to your
machine. A device file
output of the “dmesg” command in a Linux terminal also reports if the device was correctly
detected:
For the connection to the prompts of U‐Boot and uClinux, a terminal program is needed. We
recommend Kermit. It is part of most Linux distributions – the package is usually named
“ckermit”. A quick introduction to terminal programs is given on the web site
http://docs.blackfin.uclinux.org/doku.php?id=terminal_programs&s=kermit
The basic connection parameters for terminal programs are as follows:
If you use Kermit, it is recommended to create the settings file
directory with the following lines:
For fast transfer of files (e.g., uClinux images) to the target hardware via Ethernet, it is
recommended to install a TFTP server on the development workstation. This requires either
a Core Module with on‐board Ethernet capability or a certain Base or Extender board. Please
refer to your Linux distribution’s package database for appropriate TFTP packages. Also,
there is an entry in the Bluetechnix uClinux Wiki about installing a TFTP server:
