Hi
To meet the questions about the wiring diagram, I created a movie and instruction of programming VOLVO CEM.
Wiring diagram:

Thanks to Holtek, i had a success reading flash memory content. But when comparing these images with those taken with parallel programmer, lets say TL866, byte order is different. So images are not compatible at all. Tried big and little endian within xml config, but images are still with swapped words.
Can we overcome this somehow?
Best Regards

Re: cem volvo
What it says is you need proper xml for this target.
After BDM is ON, the xml file will help to initialize the target CPU to allow read/write the flash segment to be able to issue command to detect the flash.
Send me the read back of the flash to [email protected] and I will disassemble the firmware and create the xml for you,

Re: cem volvo
Come online chat and I can help you out.
If you use BDM NT read and write you do not need to swap.
If you need third party tool to analyze the data you need to swap. Use 1.00 software it allows you swap and save to a file.
