Hi
I am using AT89C55WD Microcontroller in regular use but for easy programming purpose i have tried two different ISP based Microcontroller those are AT89C51RC2 and P89V51RD2.
But i am not getting success to program any one of both ICs in ISP mode.
When i tried to do with AT89C51RC2 with Flip Software of atmel at that time i got message "Timeout Error".
And when i tried to do with P89V51RD2 with Flash Magic Software at that time i received message " Reset the device into ISP mode now" but after that i received message "unable to communicate. Failed to autobaud.".
I have connect USB to serial converter between PC and My hardware.
Select proper Com port from manage device and select baud rate @9600.
So in these both case what i have to do to remove errors?
My hardware is working properly with AT89C55WD and serial communication is also working fine.
There are lots of things to check listed here: http://www.flashmagictool.com/autobaud.html
Please go through the list, try the suggestions and report back your results.
