question about CW10.6 and MCF51MM

Hi ! I'm starting with CW10.6, trying to migrate from HS08MM to MCF51MM. With the Cyclone connected and running the debug , my application runs properly. But, when I try to run alone, it seems to be halted. Does somebody know anything about this?

hello llson,

I couldn't reproduce your problem.

when collecting Cyclone, Cyclone will trim MCU internal clock. while in MCU standalone running mode, MCU can only trim itself. please pay attention to this point.

Have a great day,
Zhang Jun

Thanks mr Zhang. I discovered that if I power up my application whit the BKGD pin low , put it to high and then resetting ( RESET pin to low), the program runs properly. I think there is some problem related with the the BACKGROUND MODE ( the ptb1/blms is opened and the SOPT1_BLMSS =0). If you have some idea, write me.

Best regards.
