TL866 Linux support

[wiss]

Maybe there should be a specific support thread for TL866 on Linux?
I would need one anyway!

I got my TL866A today 

Using the minipro utility it seems that I can read eproms,
reading a erased 2716 gives me a 2 kB file full of ones,
reading the gpib-eprom from a dmm gives me 2 kB of ASCIII-gibberish, the same gibberish several times, seems reasonable.

Writing:
eprom: "SGS M2716"

# ./minipro -p "M2716 @DIP24" -c code -w test
Found Minipro TL866A v3.62.2
Writing Code... OK
Reading Code... OK
Verification failed at 0x20: 0x68 != 0xff

Reading it back will give me a file of all 1.
Suggestions?

I would report the bug on minipro utility github - they're probably the most qualified to check what could go wrong.
But from my usage of TL866 on windows and linux utility it's really sensitive about the connections. I don't have experience with other programmers - but TL866 will sometimes happily "read" all 1 or 0 when it doesen't have a good contact on all pins (and that can be quite troublesome I must say). So maybe it's a contact/connection problem. As a last resort the official program works (or at least it did work) fine when ran in wine - so you could try that.

Good luck.

A windows computer suddenly appeared, same behaviour with the official software...

From the SGS M2716 datasheet: Vpp = 25+-1 V, Program Pulse Width > 45 ms
From MiniProV 6.00 : Vpp = 21 V, Pulse Delay = 1000 us

Is Pulse Delay = Program Pulse Width?
Anyway, this high voltage 2716 eprom is not supported.

Successfully wrote a ST M27C256B, the writing works (on some devices).
But I fail to specify the ST-version to the CLI-util, there are several entries with the same name in devices.h: bug(?), heading over to the github now.
