Hi, I'm using a C167 microcontroller for a project. In order to do some tests I'm using the MCB167-NET development board. It used to work correctly. However I have tried to use it today and I can't connect to the board via uvision2. When I start the debug session I got the message "CONNECTION TO TARGET LOST". I have check the COM port and it is correct. I can't debug any program (I tried the samples as hello and blinky as describe in the user's guide). I have tried to connect with flashtools also but it doesn't work either. By the way, I can connect to the C167 card with flashtools without any problem. (That's I eventually did but I would prefer to use the development board) Is there any hard reset or something like that I could do? Thanks a lot for your help. Stephane
What is your crystal frequency and what are the PLL settings on P0. You should make sure the baudrate error for the UART is less than 2%. I would quicky try 9600 or 19200 and see if you get a better result?
I've tried that but now it's working with 57000 bps... I didn't change anything so I don't understand why it's working now... Anyway I will continue to develop my application ! thanks for your help
