• I used Winrar 5.21 to extract the .bz2 to C:\arm-2008q1\ (warning 7zip make some .exe 0 size)

• C:\arm-2008q1\bin

• click the green [Clone or download] button on github, then [Download zip]
• Extract the dso203-master.zip somewhere

• in Command Prompt CD into dso203-master directory with all the source files from above step

• type: arm-none-eabi-gcc.exe -v

• Put your DS203 into DFU mode (press and hold >|| button and power on) and copy the app1.hex to drive.

-To get full speed oversampling, copy FPGA_281.ADR then FPGA_281.BIN in DFU mode to the device.
