XPROG 5.55 can't read MC9S12DG256 EEPROM

[lukasSVK1]

Hi,
So recently I bought XPROG 5.55 (clone) , I'm trying to read Fiat Stilo BDM (MC9S12DG256) .
Everything is connected but when I choose Secured version in Xprog software It will stuck on Bypass Security Screen and 0%
And Red and Green LEDs are blinking.

When I choose not Secured It will throw error saying "Bootloader initialising error. can't access BDM. Check BDM connection"

I'm using HC(S)12 BDM adapter. I even scratched the pins to have a good connection. I checked it 20 times and the connections are good.
I even plugged in 15V to XPROG.

Can anyone help ?


I own SVCI 2019. On another car with MC912DG128ACPV I could read it with SVCI (Abrites) without any problem .
But on MC912DG256 the SVCI (Abrites) can't connect to BDM.

BTW I tried also reading MC912DG128 with XPROG but I had the same issue with 128 version like with 256 version. But Abrites can connect to 128 version but to 256 It can't connect. Xprog can't connect to neither of them.

MC9S12DG256 : Mask - 1K79X
MC912DG128A : Mask - 3K91D

Please help

5.5.5 is the most stable of it all i believe,i can read this mcu easy with my clone.
Wrong pinout is your issue i believe.

you will have a lot of problems In future if you try to read secured mcu with almost half meter long wires
