Flash Magic and P89C669

Hi everyone,

Does anyone has experience with the phyCORE 8xC51-Mx2 developmentboard + phyCORE controller module occupied with the P89C669 controller and the Flash Magic tool?
The phyCORE controller module uses a 24 Mhz crystal.

I have checked all jumper settings on the dev board and phyCORE module as well necessary for the P89C669, but Flash Magic cannot establish serial communcation.

I use Keil demo version 7 on the PC.
Else I use COM1 on the host PC and serial port1 (P1A) on the developoment board.
I have used several baudrates, but with no success.

I got the messages: "Attempting to connect..."
Then the serial connection fails.
and "Try to reset the device in ISP mode".

Anybody knows what's going on?

Any help I would appreciate!

Thanks,

Max Veen
