+[[TOC]]
 Here I try to collect some information about flashing new firmware onto the FSC board. While the FSC has been built to be Arduino-compatible, we never really managed to install the well known Arduino bootloader onto the FSC. So the firmware can't be installed via USB, but needs to be programmed via the ISP port using an external ISP programmer like the one shown in the picture below. This is an original "AVR ISP mkII", but others should work as well.

 If you accomplished this, you can be sure, that your programmer is nicely connected to the FSC board. 
 
+== Getting the firmware ==
+
+For your convenience, you can always find the latest version of the firmware in FACTs SVN repository. 
+https://trac.fact-project.org/browser/firmware/FSC/FSC_firmware_version_from_20140318_1700.hex
+Simply check out that file.
+
+== Flashing the hex-file ==
+In order to tell avrdude to write the hex-file into the MCUs flash memory, we use the **-U** option in the form:
+
+-U <memtype>:r|w|v:<filename>[:format]:
+
+In our case memtype is "flash", the want to write so we choose "w" next, and then we just give the filename, since the format can be inferred from that.
+The entire session looks like this.
