GM E38 E67 E40 Kernel/Bootloader Development Extravaganza

[In-Tech]

Hiya Tazzi,
I'll get a j2534 interface soon, might be one in my buds snap on bag . I did buy one of the OBDX Pro VT interfaces(still in the box and wanted another toy ), is that the one you might make an update for to make j compliant? Neat stuff if you do.
Edit, I see, the OBDX Pro is stilll in development.

I want to test!

Ok so I edited the kernel somewhere in the last couple weeks which is causing problems.

Running older revision and its working fine. Will get this solved today.

For those who have installed athe app, hold off using it till next revision please

*Yep ok, messed up the section for QSPI which it used for satisfying the slave chip. Just fixing now..

I do have one of those toyota J2534 devices you see on ebay and amazon ordered but the last one they cancelled on me, see if this one shows up.. It said shipping from USA on ebay but no promises, lol..

I had one and that worked for gm SPS programming, shouldn't be any reason for it not to work with Tazzi's program..

If your not in a rush you can wait for me to try it, should be here hopefully this week..

Oh, sorry everyone for finding the one minor issue in his entire program.. I have special skills I tell ya!!!! They're not good for much, but I always put them to use!!!

Alright.. found the problem. Silly mistake on my end.

So the kernel was using the MASK and not the PARTNUMBER reported from the CPU which is used for identifying sending correct QSPI messages.

Just double checking with a few other ECUs, and also E67.. then will update newest version. Sorry about that everyone, should be solved now!

v1.0.2.20948 now available.
Tested on multiple E38 ecus, working all good now

Thanks for all your hard work.

So to answer those questions:

3) Yes will need a J2534 interface. Im currently using a VX Diag Nano and also GM MDI.
I did look at developing a J tool driver for the AVT, I had a concept design made up which I could report back as connected but didnt go any further since its quite an intensive task developing compliance. Ill be looking at adding support to the OBDX cable series that Pete and I work on since they will be J compliant.

I ordered one of these:

Appears to handle the gm sps as well.

Please tell me I didn't make a mistake.

Assuming its genuine and not a clone, it should be fine.

Ok I think the next thing to work on is brick recovery... Im going to erase the entire calibration section and pull the power.. and see how to recover.
