Quote from cpuchess on May 18, 2021, 1:35 pmExcuse my ignorance but what kind of engines can be uploaded to the Davinci Extreme units? I have numerous engines on my 64 bit Windows 10 pc but they don't appear to work. Many times the engines are built for a particular processor (e.g bmi2) but I have tried uploading just plain 64 bit version of Stockfish 13 and though it appears to recognize it, the engine never responds when it plays black (no book). So I am assuming it has to be a particular type of engine to work on the Davinci Extreme. Can someone advise?

Quote from tobias on May 18, 2021, 4:01 pmThe DaVinci extreme modules are based on RaspberryPi 4. So the Windows engines can not be used on it. You have to use engines, which are compiled for RaspberryPi e.g. for the Pichochess environment. Some engines you can directly compile on the DaVinci extreme. Herefore you need the source codes.

Quote from Pietro on May 18, 2021, 9:02 pmHi Cpuchess Tobias
We compiled some other engined for Arm processor architecture (PI devices)
Here the link https://www.certabo.com/wp-content/uploads/2021/05/DaVinci_Engines_Compiled_2021.zip
There are about 50 engines recompiled some old some new. If you like any specific engine to be compiled just let us know we can do and keep updated.
You just need to unzip the file in engines directory in PI dragging and dropping from usb stick. Remember you need to authorise the engines to be run so open a terminal in the engines directory and run this command after extracted.
chmod +x *
So it will give permission to all files.
All the best

Quote from tobias on May 19, 2021, 6:35 pmoh great, Pietro
thank you, will test them 😉
@cpuchess: Komodo would not be possible I think, cause up to now they never published the source code
oh great, Pietro

Quote from Pietro on May 19, 2021, 7:05 pmQuote from cpuchess on May 19, 2021, 6:51 pmOh right, that's true. Probably the same for Rybka 3.
Yes we checked today there is some free version but compiled and not available for pi architecture they have never been released. I think because commercial engine it will be very difficult to lock license to a pi as normally done on Pc. It shall be possible but not sure if this can be of any interest for them.

Would there be any chance of converting Bill Forster's Sargon UCI engine. Bill managed to produce a Sargon UCI engine from the Spraklen's 1978 book 'Sargon a computer chess program'. Here is his GitHub page.

Quote from DanieleC on June 2, 2021, 3:06 pmCiao Pietro, I uploaded the newly compiled engines on my DaVinci, as per your instructions. I noted, however, that some engines crash the DaVinci. For example, if I select rodentIII, or opentalxx, when the computer has to move it freezes: the lights in the centre stop blinking and stay on, while the screen keeps showing "Analyzing". The only solution is a brutal turning off and the back on.Any ideas?Keep up the great work,CiaoDanieleQuote from Pietro on May 18, 2021, 9:02 pmHi Cpuchess Tobias
