Vida CEM swapping

[vtl]

Yea that's what i did, and i got my pin as shown on the gist at the bottom of both crack attempts

Oh, you've had a success Should not type anything before drinking the first morning coffee.

Morning Coffee i just had my diner

Uhm i did some light reading and searching, is T5luke still working on the software ? and would i be able to get it ?

P.S. if i need to test stuff let me know

His sw is working with Renesas M32C. -04 CEMs run Motorolla.

I received my Arduino Nano today in order to run T5Luke's code on my 2004 V70. I have it set up and compiling the code successfully through Arduino IDE. Now I'd appreciate some instructions on what to do next.

1) For wiring power to the ECU, should I use the 5v output on the nano itself? Or would a 12v bench power supply be better?
2) Once the sketch is sent to the nano, how can I monitor the pin cracking progress? Through Arduino IDE?
3) About how much time might this take?

Thanks!

-04 CEMs run Motorolla.

Motorola MC68376 (based on a CPU32) with extra serial and CAN functions. The same processor technology used on the Early Mac, Amiga and Atari.

Seven years ago somebody was working on a Motorola68K_Disassembler geared toward the MC6876. Don't know how far the project got.

12V power supply should be better. But don't forget to connect GND of 12V power supply to your arduinos GND.
If you don't have 12V power supply, you can also use this 5V of the arduino and connect it to the 5V point of cem.
You need 5V or 12V connection, not both.

2.
In arduino ide you can open terminal and set speed to 57600. Just follow the commands then and read complete flash or use the program i have posted few posts later. It is no cracking process. The arduino reads the complete flash by debug mode of the CPU.

3.
This kind of read should take around 6mins for the complete flash. With this info you can produce so many cems as you like...

It would be nice to take a few pictures for documentation in this forum. Pictures are often easier to follow and answer 1000s of open questions for other members...

Thanks, T5Luke! I'll take some pictures of the process and write it up.

One more question: About how much current is drawn by the CEM for normal operation?

I guess this isn't likely to matter with a properly functioning CEM, but I'm paranoid about overloading it, and would like to set a maximum current limit on my 12v power supply.

Thanks again.

0.1-0.3 Amps, depending on CEM and what it is doing.

The UDS cracker seems to be working But how fast is it supposed to be? I am running this on a virtual windows 7 and I get a new seed/line every 4 seconds. Is that normal?

59 hours and I just got the pin. Success!

However, the readout seems to be failing (see attached photo). Any ideas?
