    Re: Fourplay how to

    Ok I finally got ahold of a couple computers, assembled one on a smec, how do I program this thing? Got my FTDI adapter sorted and working. Just want to flash some stock Cal's on it to verify everything is working

    Re: Fourplay how to

    I made the modifications to the board according to the merkur wiki, is there supposed to be something connected to the pad that's to the right of the "rw" pad?

    I was able to read the chip I'd after doing the board mods, came back with FbFb.
    Attempted to flash a cal to it but got a write failure due to no verification.
    Read the chiagain this time it pulled a file off and saved it.
    That's probably the write issue with the 39 series chip at work.

    I've got this guy 32-PLCC. is that Relevant to this same conversation? I'm soldering up a fourplay with similar excess of hardware due to ordering minimums. I'll post pics this evening.

    thats the exact same one i ordered. doesnt look like we can get away with the cheap flash memory. 28c010 is $33 right now.

    Totally different technology, we are working on the 39SF010 as it is slightly different to program

    I worked on this last night, so great timing for your question. We are able to communicate with the chip on the bench standalone, read, erase write etc. Currently we are troubleshooting the ECU processor to 39SF010 and its 27 control lines that operate at approx 2 million samples per second. Two of us on the project have 8 channel logic analyzer but there is no easy way to combine 4 runs of 8 signals at 8MHz and align these events to 100nS. I will see what I can do over the weekend. It would be better if we/I had a 32 channel logic analyzer but they are pricey especially for the hobbyist.
    I am sure we will figure it out, it just a matter of time.
    If you need a short term solution, the original 28c010 could be used. I personally have not tested the 28c010 but BB did sell FourPlay using the 28C010.
