"make update-firmware" is a command that you have to enter on the command-line. It will not work on Windows, though, if you do not install some additional tools (like Cygwin, and GNU Make inside of it). > I did find a program called xu1541_update.exe in a folder called > update_tool, but all that does is give error (0xc000007b). Ok, this error tells me you are using Windows. Before update_tool can work, you need to install the drivers for the device. Plug in the xu1541 device. When Windows asks you for the drivers, point it to the directory windrv/ where the drivers are located. After this, update_tool.exe should work without that error code. All the make command above does is to perform the equivalent of the following action: update_tool\xu1541_update firmware\firmware.hex That is, it call xu1541_update.exe in the directory update_tool with the only command line argument of firmware\firmware.hex Regards, Spiro. -- Spiro R.
