Newbe AVR28 board Help with ATMEGA8A

[ric...@integrity.com]

Hi 

I am very new to this.

I just purchased a AVR28 bootloader board by 100MHZ for the ATMEGA8A.

I got the com port and USB to work ok.

Every time I try to load a program on to the chip It will try several times and end with connect fail ?

Any help please.

Thanks

Richard

Hi,

Can you tell me more about how you connect the uart, and how you set the parameters?
