I am doing a project with MC9S08LL16. However, I can't download any program via a PE USB multilink interface. The codewarrior remind me a power cycle dialog saying that The target MCU is not reponding, turn MCU power on, and then click OK. It fails again after I do as the same as the dialog upon. Now the coderwarrior gives me another note "Failure connecting to device.Power cycle the HCS08 processor and try connecting again". I have check the power and ground of MCU, including BDM connection. But it seems that there is no mistakes. Thank you for your help.
