What is that? I'm very green with GitHub.

Sorry I should have explained it a little better. It was really directed at NSFW. If people follow the projects under the link they will find mybooty. I love the name for the project, before you ask I have not been working in mybooty. Mybooty has code for a bootloader that works with a trionic ecu. The trionic ecu is very similar hardware to a gm ecu. The developers had issues with eeprom chips just as NSFW has had. It is probably over the average users head. I chose to post the link and no PM it to keep information public.

If you want info on git, let me know and I will see what I can find. I remember looking at a tutorial that was good. I am happy to try and find. Others on this forum are probable better placed and knowledgeable to answer questions on it than me.

Hi all
I currently share hardware that can read/write the 411 PCM's (sorry I coundn't wait any longer for a freeware version) but I am following your progress and think this is going to be a really great addition to the family of free software that this group produce, so thank you for all your efforts.
one quick question, I wanted to try this out but on my Dell Latitude win32 machine but when opening the downloaded package it says that its not Windows 32 compatible, so do I have to build a 32 bit version myself, sorry not very savvy on building versions?

Thanks for the link, jay, I just unbricked one of my P59s so I'm going to take another shot at P59 support.

mysticpete, can you post a screenshot of the error message you're getting?

I think the tricky part of P59 flashing is a solved problem - I flashed my bench PCM a half-dozen times today and it just worked every time.

There's a bit more work to do, to ensure that random failures won't brick the PCM, but that part should be pretty straightforward.

Can you share how you un-bricked it?

The key thing was to define a new flash chip. All credit goes to the guy who made this post a few days ago:

He posted a screenshot of the dialog box. I just had to copy an existing chip definition, and change the ID number. And then it just worked. Give it a shot...

Bout time you did something worthwhile!
Now quit spouting off your good deeds and GET BACK TO WORK!
Obviously a backhanded compliment ... I happen to admire his C# coding skills very much and I do believe he already knows that!

WHOO HOO!
So it's been working all along, just no end users configured for the correct chip? ... Until now.

AWESOME WORK PEOPLES!

That is fantastic! It just goes to show how bad I am at all of this. I'll give it a try this weekend.

I'm sure I mentioned it in my BDM thread, DO NOT ever put the auxiliary programming 12 volts to the AMD flash chips. The chip has that circuitry built into it. If you do, you will most likely do harm to both the flash ram and the main board of the PCM. The P59 main board that uses the 1 meg AMD flash (2004+) is a little different than the P59 used for the older 1 meg Intel flash (2003). Some pull-up resisters and a jumper are missing on the board. I should take a picture of the differences and post it over on the BDM thread.

Because the 2003 Intel flash based P59 is an odd duck, I wouldn't spend a minute trying to get it to work. But you do what you want!

I'll see if I can write to the Intel based P59 with the BDM rig I have here this weekend too.
