Just got my DSO203 and also wanted FFT. After going through many posts I copied GABOUI_2 with DFU. The DSO203 could afterwards be started with Slot 2 (Gabunator seems to work). Starting in standard mode (Slot 1) leeds to an error message of the DSO203 “FGPA configuration Err!”.
I could not transfer files to with DFU to the DSO203. Windows 8.1 recognizes on the DSO203 the drive as “DFU V3_43_C”, but shows 1 cryptic folder + 2 cryptic files and does not accept any files. The Windows File Manager says :Error 0x80070570: The file or directory is corrupted and unreadable".
Then I formatted the DFU V_3_43_C drive with Windows. Windows stopped with an error message (something like “Windows could not complete the formatting”), but the cryptic files and folder were gone.
Then I copied the File FPGA_281.ADR from Seeedstudio onto the DSO203, but the DSO203 stopped with an FPGA_281.err.
What do I need to do go back to the original factory state? Hints from experts would be greatly appreciated from me Newby!
