Hi,

 

I'm goinf to explain my problem the more clearly as possible. I have a problem in programming my MCU, CodeWarrior say the following errors :

 

"Communication with target failed :

The target MCU as no clock or wrong BDM clock speed is used or derivative is secured"

 

Yesterday, I did my programmation correctly with no problem. But today, i try to flash my MCU and in a moment, i lost the programmation with my USB Multilink, more clearly i was disconnect during the programmation of my MCU.

 

After that, i can't program again my MCU, the watchdog LED present in the development card are already RED, and i can't reprogram for now...

 

I have verify the power supply of my MCU. Allready is good, just the PIN RESET is now to 0V... or it must be 5V...

 

Somebody can help me?

 

Thanks in advance,

 

Regards,
