Good news from my endeavors. I am able to erase and write to a P04. Code still has some issues but its enough to fully program the flash and come back to fix any miss writes. As you can see from the log, it had to rewrite the Last OS sector twice. It doesn't matter what kind of write I do, its alway...

I was able to erase a block and write 2 bytes (more on this later) on my P04. I'm working from an older version of PCM Hammer that doesn't use a loader for P04. I'm also using my testing/debug kernel. Parameter Block 0x006000 - 0x007FFF on one of my P04 is empty (0xFF) so I wrote 2 bytes to the begi...

Very exciting. Disregard what I said, I see what you're saying. I just like the option to write to flash exactly what I want. So for now with the current P04 kernel, erase and write don't work. Is there documentation how I can build on top of the existing kernels? P04_CRC_REGAL_GS.JPG All of my chan...

It been some time so that's awesome the code has been added to PCM Hammer. I guess I should update my local repo from Github. I've been writing all my kernels in ASM using program called Easy68K, I don't know if it will look the same... I took a look at the new to me version. Way more developed then...

Hey all, I'm ready to tackle P04 again. I made a few variation of a read kernel and close to finishing a micro kernel that can read and write to RAM with a few other features. All well under 2KB. But... I am struggling to write to flash (intel). Any ideas? I am ready to try something different. I tr...

Now to find a different tool to use or develop that write kernel. I'm not going to be able to test that until I get one of those 2 done or get a PCM similar to yours.

I guess its time for me to go and source different versions of the P04, since I can't replicate the data drop and the crashing of the kernel that Antus got.

I'm still working on the loader kernel when I have time, but I worry it will work for me but not others.

The Watchdog patting in my read kernel is heavily based on WinFlash which worked for Antus.

Any ideas how I can tell what the issue can be? To bad not many people are interested in the P04 PCM, more data would be nice.

That's interesting. I get perfect results even at different read sizes. I wonder what's different? I'm using OBDx Pro VT can that play a difference?

Hello all, I've put together a Read Kernel for P04 PCMs. It supports the Kernel Version command and Flash version/query command. Can I get P04 owners to test it? You'd need to load the kernel to address: $FF9076 The flash version/query command will most likely not work for P04 with AMD flash chips.
