PCM Hammer P01 and P59 flash tool v015

[Gampy]

I read somewhere NSFW wasnt posting the kernel data with the rest of the program, is that why When I compile it or run debug with my changes in cant find the kernel and I have to copy paste it from distro version?

Since im loading the kernel to a different address than it was built for could that be causing issues?

At first the source for the kernel was kept private, it has since become public.

The kernel is not built in Visual Studio, it is built from a command prompt.

Install The GCC-m68k toolchain for Windows, open a command prompt, CD to the PcmHacks\Kernels directory and run build.bat

As for moving the kernel in memory, it is easy, however things must all agree with each other, the kernel, and Vehicle.PCMExecute(...).
You cannot just change the memory address in Visual Studio, you must also change it in kernel.ld and rebuild the kernel, it all has to be just right.

In kernel.ld, `.kernel_code` must match Vehicle.PCMExecute(...) in the C# side (CKernelWriter, CKernelReader)
Of course `.kernel_data` cannot over lap `.kernel_code` and vise versa.

ok yeah I edited all of it on Program side for FF9000 It uploads just fine, but i guess since kernel still thinks FF8000 its not gonna work

no idea what i fudged up

Yea, both sides have to match.

It looks to me like The GCC-m68k toolchain for Windows did not get installed or not installed to the hard coded location that is in build.bat

made it thanks yeah changed the install dir, also had data and code over lap but fixed that

I may go into the kernel and remove all the amd stuff and write stuff to try and make a ad only kernel.

also P04 only uses one checksum its not a modular file system like p01 or p59

If you look in the kernels directory you will see a micro-kernel.c and a read-kernel.c, very educational pieces.

thanks gampy, guess its time to acually learn coding

A simple demo, used PcmHammer to start a Quick Comparison, once the kernel is loaded, use Task Manager to End Process PcmHammer. (no hurry, wait until it starts requesting CRC's)
At that point, open PuTTY (or your favorite Terminal Program) connected to the same comport PcmHammer used.

Once PuTTY is open hit enter ...

Byte explanation

ReadMode35Demo-ByteExplanation.txt

Why Mode35 returns as 36 is unknown to me ... Typically 40 is added to the command, this one may be different for some reason I do not know, that's up to those smarter then I.

Hope this enlightens someone ...

when i type in putty it gives weird characters ot what i typed

[Gampy]

Sounds like a comport speed setting issue.

all fwd v6 cars from 98-05 also firebird camaro v6 cars

3100, 3400, 3800 engines some 3500

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.

As a reminder, I know NOTHING of these modern (Computerized) GM vehicles, I wouldn't know a grand am from a modern GTO or from a Cavalier, or what the F-body or J, N, U, and W platform vehicles are.

I am not a post seventies GM aficionado ...

So with that said, can I get a service number (multiple preferred) for one of these v6 Pcms.

Thank you
