MPC564 - no BDM communication after writing a byte

  • Hi,

    I attempted writing a byte into the internal flash of a MPC564 using a Multilink programmer, and the operation failed; however, now I can't connect to the MCU via BDM anymore. The HRESET pin is always low, and DSDO, VF0 and VF1 are kept high.

    I've searched the datasheet for a description of that state, but could not find anything. What could be the problem, and how it can be resolved?
