We might need to drop the crc code and maybe more still to get the file size down. Also if we cant do multi part uploads we may not be able to support a number of interfaces, or might need a small stub that can run then take further segments.

Dig out the old micro-kernel.c and add some interrogation routines, use PcmHammer to upload it, task kill PcmHammer and use PuTTY to run the interrogation routines.
At least get a running kernel on it ...

I have no clue what those vehicles are except the Firebird and Camaro.
It might be enough for my supplier though.
Now that you have v4 kernel running, try killing PcmHammer and using PuTTY to do Mode35 reads, to investigate where the Flash starts and ends ... It would be better to use a custom kernel though.

Hi all,
Gampy, in addition to the F-Body cars the PCMs are mated to V6s in Chevrolet small and mid sized front wheel drive cars such as the Cavalier, Malibu, Impalla, and Monte Carlo as well as the Venture Minivan.
Also in the Oldsmobile and Pontiac cars (and vans) using the same Chassis - GM J, N, U, and W platforms.
Mike

You have one for the 2005 Venture?
I currently have one after having my 2004 Alero totaled by an idiot pulling across a 2-lane State Highway when I was about 100 feet from him!
I would love one to compare it to the one in the GA GT.
