I tried to read BMW CAS2 mc9s12dg256c by using Xprog V5.55 programmer. It gave me communication error. Can you point me which I need to choose to read or the correct way to read with Xprog-m box?
Xprog m ecu programmer reads good on this ecu.
Step 1: Xprog > Device > MCU/MPU > Freescale HC(s)2-secured > MC9S12-EEPROM-secured (at very bottom)
Step 2: Xprog > File >New Bin File.
Step 3: Xprog > Run > Read
You may want to take a little more care with your connections. Cas is easy to kill. Your Vdd and BKGD looks to be bridging.
