Daewoo Matiz HC05H12 (0H57A)

[468]

Hi!

I have a big pain with this dashboard from Daewoo Matiz with 68HC05H12 (0H57A). I use xprog-m v5.0 but i can't communicate with device. Always device silent on xprog-m.
I tried almost everything. I lift pin 46 only. I lift pins 2, 43, 44, 45, 46. But no result. I use always the connection diagram from xprog-m manual. Device is silent always. The xprog-m use 4.19MHz xtal freq. The next step is try to purchase a new 908 programmer with hc05h12 support or UPS-USB v1.2.
If someone read & write this dashboard with xprog-m, any help are welcome.

You're don't have a problem in connecting X - prog with processor , you have problem in connection X-prog with your computer :laugh:
1. Run X-prog program
2. Option
3. Environment option
4. Ports
5. Chang port connection between X-prog and Comp.
And your problem is solved

The connection with xprog and computer is ok. I use it for other eeproms and cpu and everything is ok. I can't communicate with this cpu. Also i use serial communication between xprog & computer + 15v DC external power.

That processor read only with USB connection not extern power 12v . From my experience when X-prog write "device on silent" comport is change

My friend can you tell me what connections you use for xprog-m and 0H57A? What pins you lift or not? Any jumbers between pins? The crystal on board is 4.194MHz or you change it?

Regards & thank's for your support.
