I think it's not possible to perform In Circuit Debugging (ICD) on a st7lite09 part. I hope it's that you mean by ''debug online''. Indeed, there is not debug module on the chip. So you can only program it but not debug it. Regards, Seb
it looks as if the STICK really is not suitable for online debugging. I only found hints to applicable development tools in the manual at chapter 15.3 DEVELOPMENT TOOLS. Hope it will help you. Regards, WoRo
STVD can debug through the ST7-STICK, this feature has been introduced since few monthes. As Seb13-colin told, the device need to have a debug module to support debugging whatever is the tool. Best regards Laurent
