If using Linux, you can use ''dmesg'' to verify the serial port was connected OK.
==BOSSA Command Line==
On certain systems it may be easier to use the command-line version of BOSSA, called bossac. You can also build just this version if required (see instructions below).
You can also run the BOSSA utility at the command line, with an instruction like the following:
bossac -e -w -v -b /path/to/SAM3U_CW1173.bin
If you are on Linux, you may need to either fix permissions on the serial port, or run bossac as root/sudo. See below for details.
=== Linux-Specific Instructions ===
You may need to give yourself write permission for the serial port. This can be done on some systems easily by adding yourself to the <code>dialout</code> user group. For example, assuming your username was <code>cwuser</code>:
# <code>$ sudo usermod -a -G dialout cwuser</code>
# Log out and log back in again for changes to take effect.
You may also need to build bossac from sources, as the provided binary does not work with your system. Details of how to perform this are provided next:
To build BOSSA, it is recommended to use our simplified bossac repository, which only builds the command-line version. To build this perform these steps:
# Download [https://github.com/newaetech/BOSSA/archive/master.zip a copy of the GIT repo], or clone with <code>git clone git@github.com:newaetech/BOSSA.git</code> (see github.com/newaetech/bossa for the full repo).
# Unzip the directory if you downloaded the zip.
# Run <code>make</code>.
# The binary should be in <code>bin\bossac</code>.
