PCM Hammer P05 support

[darkman5001]

I think I've killed this one. Its cold here and I had trouble getting the back off and managed to go to deep and chip off a resistor and a capacitor. I didnt notice until after the cap was lost, and when resoldering the resistor back in to place it kept sticking to my smd tools then flew off never to be seen again. I thought if I was lucky that might be in an analog part of the PCM which does not matter for reflash development, but I cant get it to detect the flash with BDM, and I have a feeling it may have something to do with power or pull up of the flash chip. I'll have to order another PCM which will probably take another month to get here before resuming work on the P05. Its a good time to work on getting the next release of pcmhammer out anyway and getting P04, P08, BlackBox out there.

Antus, I have information about the P05 BDM connections if you still need them.

Does your information match this? This is what I tried.

And I used the E40 config file, which from here also works on the P12. I can see the similarity to the P12, but I also see addresses configured which dont match part of my flash tool code, so it may be that I need to make up my own config file based on what I have learned so far. If you have any details about known good usbjtagnt configs for P05 that would also be helpful.

Side thought - interesting that if the E40 config file works on the P12, then the P12 code in PCMHammer might be just working or very close to just working on the E40.

Okay you have the same information I have. Sorry I couldn't offer more.

Thanks anyway

Thanks to the images here I was able to see the resistor Ive lost is 223 eg 22K Ohm, so I could potentially replace it. The capacitor is also pictured but they have no values on them. The second pic in that post (thanks geep!) shows the lid cut off the P05 on the other side and I can see the location of the flash is a fair way away from the components I've lost which gives me some confidence that the problem I am chasing is not the components.

I took a close look at some images I took of my connections to the PCB and I can see I had one of the pins not quite soldered on, it looks like it was just flux holding it in place. So I revisited that. And then the DSCLK line fell off. It was longer than the other lines by a tiny bit just because it made everything fit more cleanly without that one wire having more force on it, so I took the opportunity to trim a couple of mm off the end and re-install it. Still no good.

This is essentially exactly what my attempts on the P12 with the E40 config file looked like. I am starting to think that those people who shared the BDM configs and reported that the connections worked might have had the skills to create the BDM config files out of the OS, and forgotten they did it and havn't shared a missing piece. I cant say for sure, but even though the power/data pinouts for E40, P12, P05 are identical and the operating systems are similar by generation, if the BDM config files I have are not right, then its never going to work until they are properly created.

We have flash working on the P12 so I could try that again first and poke the values we know we need in to the right registers in a new config file, but that's a whole lot of really small soldering to get started again on that platform I dont have time for at the moment.

Found a cheap P05 on ebay US today, $50 in the local currency delivered. Its on the way.

if you need any testing on the p05's i have 10 or more i scrap alot of cars . I also have a avt 852

If anyone is still interested in these,I read this P05 with ulinkNT,bdm.I'm not having any luck unlocking CAN or VPW.Did anyone find the gmlan algo?

[Brian_Griffin]

A little progress.....gmlan algo is 35 for this pcm
seed/key = 1C3F/8CA9

Would you be willing to share your connections to the board and also setup in ulinknt? I have a u-link and I have been trying to get successful reads with the P05 for months. All I keep getting is "Unknown Flash Type" no matter how I configure it.
