need help reading mcu

**ninja123** · 31st October, 2014, 08:34 AM

Can anyone help me, trying to read HC05 mask 0D62J QFP64, with xprog, mcu is from 1998 mercedes sprinter.

xprog says device is silent, I try with power supply too.

Any diagrams or settings would be great.

Thanks in advance, ninja

Remove MCU from board and solder to qfp64 adapter and you can read it without problem.Dont waste time to try read it onboard with xprog.

Did you solder xtal 8000 or 16000 MHz to adapter near mcu?Without xtal you can't read MCU.
Which adapter you use?
You must use this adapter

You must get this adapter when buy xprog device.
Here is pic with marked pins for xtal,but soldering is from other side of adapter.Try and you will see what is magic of read/write hc05x16/32 with xprog.

And guys,if this helpful dont be shame to hit thanx button
