hey everyone just another update here
the latest is I got a brand new mesa 7i77 out of the box and tried it and that didn't work either when connected to the 5i25 that I have been using for testing So I decided to swap the 5i25 out and use 6i25. I flashed the 6i25 with the correct firmware and everything worked fine. then tried the old 7i77 card and it worked fine too. then connected up the 7i77 and 7i76 to the 6i25 everything works the 5i25 works fine when using only 7i76 cards which is what was originally in the board so my conclusion is that I must have a older 5i25 (it is 3 years old) and maybe it needs the firmware updating I have read that the older cards need a hard reset just so happy I haven't blown up any cards though. and so glad that peter (mesa) decided to protect against putting the 5v control power on backwards lol Now I want to update the firmware on the 5i25 so I can use it also as I need it for another machine I have here (the second VMC) and want to try out the 7i84 I have and see if the smart serial works ok any thoughts guys? whats the easiest way On Sat, Nov 21, 2020 at 10:09 PM andrew beck <andrewbeck0...@gmail.com> wrote: > ok just did some more testing > > I have two 7i76 cards connected up now and everything works (using second > connector on 5i25 for extra 7i76) > > I am wondering if I have broken the 7i77 I have which I ran 5v backwards > through. > > is this possible to do and if it is would I expect a communication error > as a result of it? > > If I have broken it that would be a bit sad haha > > > > On Sat, Nov 21, 2020 at 9:40 PM andrew beck <andrewbeck0...@gmail.com> > wrote: > >> ok just did some testing >> >> when I flash the 5i25 with this 5i25_7i76x2.bit file it all works fine >> >> this is just with the 7i76 connected up >> >> when I try to connect up the 7i77 and flash this bit file >> (5i25_7i76_7i77.bit) into the 5i25 I get a issue >> >> the 7i77 is coming up with a red led though in CR16 I read in the manual >> that this goes red when there is a communication error with 5i25. >> >> now I have just discovered that I powered the 7i77 with 5v and had the >> polarity wrong so was trying to send -5v into 7i77.
