4.3 Desktop “Helper” Applications
4.3.1 Flashwriter
This is an application to program the FPGA configuration memory from a BIT file. You will need to
run this program if new FPGA firmware is made available and you want to install it.
The program may already be installed onto your linux desktop. If not you can run it simply from a
linux command prompt. Open a command window then type:
• cd github/Saturn/sw_tools/flashwriter
• ./flashwriter
Usage:
Opens a dialog to select the file to be programmed into the memory,
The only format accepted is a .BIN file (a Xilinx binary format)
Selects which image to reporogram
Primary (this is the normal image to program)
Fallback (CAUTION: only reprogram if absolutely necessary)
When pressed initiated programming; this may take 2 minutes or so. The steps
are displayed and progress for each step is shown in the bar display.
Erases the complete FPGA. Don’t use this unless you know why you are doing it –
this is not a normal programming stage!
If your power supply fails during the programming process, the image will be corrupted. Your radio
will still load, but using a “fallback” image. This is is likely to be older FPGA code. You will need to
repeat the process when power has been restored.
It is possible to reflash the “fallback” image although the need for doing that is rare. To do so you
would select the Fallback button. The fallback image is over twice the size and takes a few minutes
to program.
