Custom leonardo error message.

Hello Friends,

I have made a custom board based on the Leonardo. It is an exact Leonardo clone.
I am trying to program the bootloader via the AVR ISP tool.
I am getting the message as follows -

"status: RST fail, Target reverse inserted
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to
"
Any suggestions please.

Regards,
Vinod.
