Hello everybody

I work with C8051F060 micro-controller and I
use C8051F060 DK target board, so I have
USB serial adapter too. I must put a program in my
micro-controller and then solder the chip into separate
application board. For this purpose I've made a C8051F060
programming board. Circuitry of this board is very similar
to one on C8051F060 DK target board. In fact I've tried to
make my environment on my programmer identical like
that on the target board.

On my programmer board I leave reset-circuit, oscillator and JTAG connector of course. I lead power supply directly from target board
( pins A1 nad B1 at ABC 96pin Eurocard connector). So,
all conditions are similar those on target board but
when I try to connect to from Silicon Laboratories IDE
i get this massage:
"Communication could not be established with the
specified serial adapter. Please confirm the current
'Connection options' selections. "

I have tested my circuitry, I have measured every pin potential, I have
even tried to program several C8051F060
micro controllers, but result was always same..


Please help me and tel me what I do wrong.
