problem to communicate with Hyperterminal

antoine KEHRLI

Hello,

I'm a newbie in ARM and in Keil Microvision IDE. I downloaded an example from st site, which allows to communicate via serial port with an hyperterminal.
I compile then download the program in the ARM7. When I am in debugging mode, I can see the program works properly thanks to serial window inside Microvision.
But When I want to use hyperterminal on my PC to communicate with STR7, nothing happens...I take care of using correct settings for serial comm, same settings than in STR7.

Could you help me please?

    Hello,

    Thanks for your answer!

    DB9 connector on my Hitex EvalBoard (same than MCBSTR7 Board) is female. But even if I use a straight-thru cable, nothing works...(I verified ppin to pin connection on my a straight-thru cable ).

    I tried also change db9 port on the evalboard (since there are 2 serial port) but normally UART0 matches to RS232-A port?

    I wonder also if there is a possibility that baudrate is wrong, since it depends on a clock speed (RCCU_FCLK). I mean in target option in microvision, there is a setting for XTAL Clock, where I wrote 16 Mhz.

    Thanks for your help
