Problem USB BDM (HCS08/HCS12/CFV1) with MCF51EM

[Montelo]

Hi,

I have a problem with programming the CFV1 Controller MCF51EM. In my testapplication for programming the controller in our production a new or unprogrammend controller needs an Power down/off of the controller. As this is not realised in the testapplication I want to ask if someone know if there is a posibility in the settings to solve this that no power down/off is needed?

Best regard

Hi Sezgin,

Unfortunately the only guaranteed way to get a a MCF51 into BKGD mode is through a power-cycle with the BKGD pin low.  This is described in the device manual.

Often it is not necessary - but in many cases for  blank device it will be.

This is independent of the programmer used.  Some programmers provide the ability to cycle the power when required.
