    Hi all.HI.thi is my first steps to programing in ARM. I began programming software in str911fm44. I use STX-link and raisonanse development tools. I have several problems:

    1) How connect j-tag 20 pins to str911fm44 ?

    I d'not find to ST sites example

    2) I connect j-tag connetor via example F-link (st www sites) 14 pin connector. At present time, I can olny programing flasch memory, and run program it is OK,

    in debug mode I Have message ''unable yo communicate witch target CPU''. How run i debug mode (may by jtag conetetcor is connected improper (badly)?

    3) I have a problem witch initialize PPL clock mode all function returns error: (SCU_PLLCmd(DISABLE)-ERROR,SCU_PLLFactorsConfig(_PLL_N, _PLL_M, _PLL_P)-ERROR,SCU_MCLKSourceConfig(SCU_MCLK_OSC)-ERROR, without one ( SCU_PLLCmd(ENABLE))

    I use library stdlib from St site

    If possible plesase send me example with initialise PLL clock (I Use crystal 11,0592 Mhz)value PLL_M, PLL_P PLL_N generate caps software.

    All examples from st site not run.

    only function printf is ok.

    while(1)

    {

    printf(''U'');

    }

    I obsere wavwform to scope uart0, node TX0, spped is not compatybile with standards uart speed, one frame about 2 ms

    please help me. best regards Mariusz
