Hello,
We are using ST7MDT10-EMU3 kit for programming ST7FLITE29 Microcontroller. We are using ST7 Visual Develop IDE with Cosmic C compiler. We get following error: -------------------------------------------------------------- Device: ST7FLITE29 Board: ST7-EMU3 Port: USB Programming Mode: ICP OPT Disable Tasks: Unlock Device Blank Check (if feasible) Program Verify Unlocking Device... Error : Cannot communicate with the device ! Option Bytes are Disabled on the device Check the ICC cable connection and check all the needed pin connections on the ICP connector Clock is 'External source' in this ICP mode On Application, connect OSC pin from ICP connector or an Oscillator or a logic clock Error : Programming failed on Option Byte done Initialization... > PROGRAM MEMORY << ''D:\BottleCooler\Debug\timer.s19'' done Programming... PROGRAM MEMORY: > Blank Check not feasible > Programming Error : Cannot communicate with the device ! Option Bytes are Disabled on the device Check the ICC cable connection and check all the needed pin connections on the ICP connector Clock is 'External source' in this ICP mode On Application, connect OSC pin from ICP connector or an Oscillator or a logic clock Error : Programming failed. ------------------------------------------------------------- Also, if we make option byte enable then also we get the same error. Please guide me. Am I doing it correctly? or Is there any setting that I have forgotten? What are the possible causes of the error? Thanks Mohit2005-11-16 10:43 PM
Mj, did you try to replace the ST7FLITE29 with another one?
The same error happened to me (but I use InDART). The culprit was the chip itself: PB4 port pin was broken... Check also the clock levels with the scope: they must be TTL compatible. Bye EtaPhi
