    Attachment 10139 then this is with the t and e side checked plus the lower write latency checked. when i first tried with the lower latency checked it did this error twice on the t side plus had the error from the previous pic i posted.. so just for shits and giggles i did it again and it was only one error this time.



    hold on a min and let me do some port setting investigation on my pc.

    well the port setting was changed it was at 912600 so i put it back to 9600. with just the t and e side checked it flashed fine. then when i checked the lower latency it gave me this.Attachment 10140Attachment 10141Attachment 10142

    those are a lot of different errors. I'm glad it at least manged to salvage things.

    the "latency" setting has nothing to do with the erase or reset procedures.

    also the serial port setting, do you mean the one in the device manager? those settings don't mean anything, eehack overrides them all..

    what serial interface are you using?

    I did increase delay times a bit in this beta, I thought it would be safer and not the other way around. maybe it had some unintended consequences.

    looking at this logically, high delay times really seem to screw up sequential mode6 requests. I think there must be a timer in the routine I didnt anticipate that requires the request to be made in a certain timeframe.

    How would you figure out when to write the auto stuff?

    by checking for bit 6 offset 0x2026 on the t-side. if the bit isn't set (as in a manual bin), none of the automatic transmission code is run and the tables aren't referenced anywhere in the code

    so my plan is to get that socketed ecm working this weekend, and do some serious testing regarding timing during mode 6 programming and the flash procedure. i dont like all these errors that are cropping up.

    I recall that auto bit not being usable, meaning it's not the flag or not the only flag that switches transmissions.

    the eex xdf when first released didn't specify the correct bit. this is a bit that's always set for auto trans. I've compared lots of bins to make sure.

    I get the Floating point exception (core dumped) when trying to analyze this log file.

    no doubt it crashed it! that log shows a total length of approximately 90 days. try graphing it and you'll see what i mean...

    i'd like to know how this happened, but it also reveals a fundamental problem,

    i think i need to ensure on loading the first log, that the initial timestamp becomes 1msec. i thought i'd already done that, but i guess it's not working.

    but also, how the hell did the initial timestamp get that high in the first place?

    eehack's timestamps are supposed to be relative to the first record that's gathered.

    what eehack does at the moment is grab unix epoch time and use subtraction to get its timestamp. this might be a really bad idea as that clock source isn't necessarily monotonic, meaning if the operating system decides to change the time, things could go haywire. i should probably use a different timer.

    in this case though, i doubt you had 88 degrees of clock skew within the timeframe that you started the program.

    is this perhaps on linux? it's possible you discovered a bug introduced going from 32 bit to 64 bit... maybe something wrapped?

    i'll look over all my timestamp code.

    im looking into the flash problems too and found some fundamental problems with how im doing post-delay timers.

    new beta, please test it for me. i hope this fixes some of the flashing issues, but who knows.

    also i changed how i did mode1 (the main data) timing, please let me know if your packet rates are better, worse, or the same.

    can't wait to get my test bench back so im not working blind

    Very strange, I didn't do anything different, had just logged earlier, then I took a trip and decided to log it. When I went to analyze it it crashed. The log before it was fine, the log after was fine, just the one. It is linux, 64 bit.
