P89C51RD2

[Harnam]

Hi  Folks!

Greetings

I ve connected P89C51RD2 to serial port via MAX232. In hyperterminal,the chip is detected. When I use Flash Magic, "No detection".
The chip refuses to switch over to ISP mode, after resetting also no detection. Earlier, there 's detection and I performed Blank Check, etc.

Can anyone one suggest me some tips ?

Regards

Yes. Please read Flash Magic application Note 4 on the Flash Magic web page. There you will find a collection of steps to try to resolve the problem you may be having. If you cannot resolve it then the application note describes the steps required to send more information to us.
