\hypertarget{standard programming}{Updating} the firmware on the \gls{tlu} requires writing a bit stream file to its \gls{fpga}.
This operation is performed using the left \gls{usb} port located on the back panel, labelled \verb"FPGA PROGRAMMING" in figure~\ref{ch:backpanelintro}.\\
Once the Vivado tools have been installed the user should also install the drivers for the programming cable in the enclosure (see previous section for software sources).\\
The bit stream is provided as a \verb".bit" file and can be found on the firmware \href{https://ohwr.org/project/fmc-mtlu-gw}{\gls{ohwr} repository} for the \gls{tlu}\footnote{https://ohwr.org/project/fmc-mtlu-gw/wikis/Firmware%20Releases}.\\
