Problem reading PSG16 flash via BDM

[spast]

Hi friends. I am trying to read and write all memories from Opel Psg-16 by BDM using x-prog. I make BDM adapter using my 3D printer and successfully read eeprom and mpu, but when try to read Flash chip have error that flash chip is unknown or missing. According to info found on the net I powered board with 12 volt on power pins. I check that vhen connected there is 3 volt inside.
If anybodi have experience connecting this kind of board using X-prog -please suggest where is problem. I cannot use another BDM tool becomes my Fgtech galeto is broken. Thanks.

As far as i know external flash is not wired "standard" way to mpu and that is why you have no access via bdm. Guess you should rewrite the bdm payload to fit the nonstandard wiring of the flash.

Hello mates, here is my files readed through BDM and Xprog, Flash,eep,configA,configB.Winols recognise the flash file like EDC16V2 but cannot find maps.

Thanks M8. I have no skills to do that. My tests are based on pictures from internet. The last thing that I will try is to rewrite MPS internal flash with other type ECU with same MCU .
