RomRaider

Just got my VQ25DET up and running last night (taken ages to find a spare loom for these).

Doing ROM dump at the moment with nisprog/NisssanDataScan. Found I had to connect a few times to get it going (same issue was found as TB48 patrol)

AUD port is the same as the TB48 AT patrol if you look at the Piasini diagrams for hookup. SCI pins are all over the place, but can be found by tracing the lines from the 7055.

Looking up of sashas posts with the SCI pin locations from the 7055 (in the subaru section on this forum) confirmed my test points

I'm not sure there is a WDT timer pin for this one (usually external controller chip, but this ECU doesnt appear to have any external chips) so I will have to monitor the RESET line on the 7055 to see if it WDT does kick in

Hmm, strange - do you have pics of the ECU innards? is it a twin-cpu model ?

> Connect a few times
yea... fast init timing is finnicky at best. As Sasha pointed out in another thread, running a media program in background (audio player, whatever) may actually be beneficial as they seem to often reduce the OS tick interval. Previously I recommended running as few programs possible in parallel, this may be the exception !

But yeah, for those who may have missed the update on the campaign page - the funding goal was met (HUGE thanks to everyone who pitched in !), I'll release the initial source code and compiled kernels within a day or two.

Again, thanks a lot to all the backers, this is going to be great!

Source code is now up :
https://github.com/fenugrec/npkern

precompiled kernels coming soon on the repo, as soon as I wrestle git into submission. I'm including one here for 180nm devices (7058 and newer (maybe uncommon) 7055)

Woohoo! Excited to mess with it. I'll be sending my 370z rom asap. Thanks for all your awesome work.

Wow that looks like pure awesomeness! the best contribution for nissan & SH705x crowd, big thanks for that!

I'm eager to mess with the kerns. What compiler were you using? I'm going to fire up the crossdev and build the compiler, wonder if I should start with something rather old (aka stable) like some early 4.x version (4.1-4.4)?
UPD: 4.1.2 & 4.9.3 are OK (haven't yet tested the binaries with the ECU)

Looks like stripey beat me to it. Same as ECU here:

Silly question but is there a similar thread on ECU Flash to have this implemented into the Tactrix cable? I know you mentioned its trivial to make the changes to that format. Just trying to catch up on the sections ive been missing in romraider!!! Awesome work btw, i think you sold yourself short on the goal though

Sorry must've missed your post - I'm just using the latest gcc build provided on https://gcc-renesas.com/
but I'm pretty sure which version you use is of no consequence, as long as it's less than ~10 years old !



no idea, you mean on the openecu forums ? I tried registering there once or twice and failed, so screw them !


Thanks - but as it is the goal was only met at the last minute thanks to someone generous who saw the value of this. Despite the extra "stretch goals" that I thought interesting, there wasn't that much traction after all.
That said, I do accept private donations (beer, gold coinage, etc ) even if the campaign is over ! P-)

Anyone successfully flashed with the kernel yet?

heh I assume you mean "except me" -- I've reflashed a few blocks about 6-7 times tonight on my bench ECU. Stay tuned for important changes to nisprog "soon", i.e. different command syntax and "more better smartness" in determining which blocks to flash etc.

Hah, yeah of course.

Although it's exciting to hear about "smartness" for per block flashing.

I really want to test this out on my old Sh7055 stuff to see if it will work at all. I'm assuming that everything I've been messing with is .35 chips and not the latter stuff that's more similar to the Sh7058 so it may be futile.

My car is almost back on the road so I will also be interested to see how this works on the 7051. Managed to get a newer model ecu with a 7055 Processor in it but unable to figure out how to get the NATS.... Sigh

Okay so now that I've played around with the kernel a bit here's what I have done (this was done on a Windows Surface Pro running Windows 10):

EEPROM dump
Full ROM Dump (1 MB ROM in 3:30 mins, avg 4.9 kb/s !!)
Block 12 Dump
Block 12 Reflash (128 kb in ?? seconds, I would guess around 4 kb/s)

I think that's everything.... either way, verified to be working on my PC / ECU

Awesome!
