Hi,

I have STM8S207C8 on my board and I am trying to debug my code. After some tests, today my RLink debugger has started to give an error like that:

>> Communication error: Timeout error sending on USB: WDU_Transfer() failed: error 0xc0000005 ("HC status: Device not responding") <<

If I power off my board and supply power from RLink by closing (short circuiting) "PW-5V" jumper on the adapter, I can program my micro successfully.
What is the possible source of error?

I have another RLink debugger also but my PC isn't able to find a suitable driver to make it work. I couldn't find a driver on the Raisonance web site and the CD enclosed the RLink debugger box also.
How can I find the driver of RLink debugger?

Thanks&Regards
