Motorola MC683XX and reading, writing external Flash via BDM

[Holtek]

I am looking for a programmer who will read and write Flash working with MC683XX. This is not ECU, so K-TAG or Galletto does not work, they do not have scripts, they count check sums. I calculate checksums myself. The programmer needs only to read and write external flash 28F800 via BDM. That's all.

Best regards

XxBackup also can not scan through a motorola

Although the MC68376 and Flash 28F400 processor is often present in many ECUs, unfortunately, but CEM can not be read and written using Galletto, K-TAG, because they do not contain the necessary scripts.
However, there is a programmer at a favorable price that handles without problems.
To meet the questions about the wiring diagram, I created a movie and instruction of programming VOLVO CEM.

If you don't mind desoldering the flash memory, the GQ-4 programmer will read and write 28F200.

Tried to read with usbbdm. Got read out flash, but could not erase either write any changes. Tried to pull up some of the flash pins. No luck.

Connect Wpp to +12V

Thank you. Although i have tried to pull up Wpp, i will make it a try once again with your scheme.
What device did you choose from the USB BDM software?

Thank you, Holtek!

If you can read but not program, it is simply not initialized properly which can be fixed in the definition xml.
