if we knew why it happened and it was reproducible it would be handy, but it must be a rare fault. you don't see a lot of cars rolling themselves back from a dead battery.

solar flare ?

it's definitely not supposed to do that - however if it is truly at zero miles i think you should be able to reprogram it in-car without using the 'reman pin'. i think it'd be more likely that it's...

don't really have time to get the ccm test bench set up again - but let me know if i can build any more crap into flashhack to help, it's a good platform to add crap to, to test whatever on an aldl...

feel free to beat on datastream_8192::resync_datastream. it's a bit confusing and terrifying and like anything you touch will break it, and you corvette nerds are the only reason that it is like...

i wrote eehack in a 600 sq ft apartment with a bunch of crap duct taped and tiestrapped into a desk drawer. an elaborate test bench would take away development time



now as far as the unlock...

it kinda bugs me how the ECM code just goes ahead and barfs the seed/key for programming on ram dump. actually barfs the whole bin with no authentication, so one could track down the code that...

i do remember that if the 'security light' is on, you can't reprogram it.
that is definitely annoying
there has to be a decent hack we can come up with for people with wrecker ccms they need to...

the flash tool for these things never got well tested beyond my bench
definitely interested to see if it works for you

okay

if anyone from this forum needs a working CCM with unknown crap on the flash area and a mysterious jumper wire let me know

i just found one

eehack uses that silence f9 command because another logging tool uses it and one of my users had convinced me it was necessary
i'd never proven it and had no trouble without it on my 1994 or 1995...

you're right
flashhack is too strict
it was rejecting the reply as the request/reply first byte has to match in flashhack land
makes sense if idle traffic isn't present but otherwise not

it certainly should if it's following the rules

i don't remember.



i can't make the thing work. mode 7 was supposed to be a request from the tester to the CCM to transmit a normal mode messsage. should need a byte to specify which normal...

also the eedata format is dumb. i think its actually fixed column size to decrease parsing time. i could improve it but not going down that rabbit hole.

you should be able to trigger a ccm broadcast msg of your choice once you have become bus master. i have documentation of it. i will get you details and test the theory.

why the large hole?

i will start a new thread about this to stop polluting this one with non-CCM related stuff.
edit: also pulled the new version till i fix a few more things

it turns out for some reason nobody has noticed that EE flashhack was clearing a totally incorrect region on the t-side (actually it's been clearing bytes in the ram area instead, due to a typo,...

actually i think you might have just uncovered an issue. might not want to use that new version to do a complete flash. i'll report back.

yeah you can press unload kernel if you wanted afterwards

if the bin you've loaded is unchanged (except for the eeprom) just press flash write and it should take care of things

one unresolved...

i have released the new version to play with.

the DBG_C button in the advanced section writes the eeprom only if anyone wants to try that too.

i don't know about that.

i think the work you're doing is on the same scale as the work i'm doing

it serves no real purpose in the grand scheme of things, and you will succeed and excel and...

task complete, this assembly code has now infected EE

you all have a fully permanent tuning area on the TSIDE that we can program quickly and safely, and all you have to do is relocate whatever...

i could experiment with that a bit, but i agree it might not be a really big improvement. the overhead of requesting an aldl message is really low, but i guess we might get a few more extra bytes...
