Re: Relatively inexpensive PowerPC debugger?

He has only just started reflashing/accessing via Nexus in the past few weeks.

Itll be worth contacting about it.

Re: VZ PIM

I feel like around that 0x70/71 location, was the number or resets.. I think??? Maybe 75/75?

You'd know straight away after doing a reset.

Theres also a counter for how many incorrect immos entered.

Re: Relatively inexpensive PowerPC debugger?

Does anyone know of a relatively inexpensive PowerPC debugger? I've got a few projects with MPC56xx chips, and the code is just too complex to fully work out in Ghidra alone. It doesn't need to be anything fancy. I just need something that can halt the chip, read memory and registers, and step thro...

Re: Ford AU eec-v pcm .bin read options in 2023

I feel like i was using something like PCMFlash or one of those tools that flashed the EECV ecus. This is going back a while when I was working on PWM support but I think that was the one?

I was using a AU ECU on the bench when testing it all out.

Re: More ELM327 Fun (Read: Headaches)

While I understand what you're saying, I was trying to pay for better quality units, but I don't think they are available anymore without jumping into a whole other category (like I did with the Nano, or the Pro GT). I did not mean that in a bad way, just the fact that the genuine ELM chips were ab...

Re: GQ USB Programmer Software failure?

Installed the software on my desktop PC, manually updated the driver for the programmer and it all works so really unsure of what is happening on the laptop. I had exactly this issue on my main computer, and eventually on my laptop also after it did one of the win10 major updates. Windows updates h...

Re: More ELM327 Fun (Read: Headaches)

Getting ? when sending ATMA is one of the aspects of a emulated ELM command set. Theres a write up online somewhere that I read where someone bought a bunch of ELM cables and there were a bunch which had the CPU etched off (No writing) and they didnt work with a bunch of commands. Typically VPW (J18...

Re: Trying to monitor the data bus with an ELM327

Also, does the statement from the previous post which ends with "...or a (good) J2534 device" imply that the VCXNano I purchased isn't a "good" device? Are there any other reasonably priced (meaning for a hobbyist like myself) J2534 devices available? My issues with the VX nano ...

Re: Trying to monitor the data bus with an ELM327

Sounds like its not receive the actual command properly.

All ELM commands require a carriage return at the end for them to register.

You will also need to set the OBD Protocol before trying to send ATMA, since the ELM needs to know what OBD protocol it is using before it can start monitoring it.
