Jamie Murray is targeting Rio doubles success with brother Andy to make up for past Olympic disappointments.
The Murrays have never lost a Davis Cup doubles rubber but crashed out in the first round in London 2012, with Andy going on to win singles gold.
They also paired up in Beijing in 2008, suffering a second round loss.
"It's four years to sit on that result, for me personally anyway, so we will be trying our best to do as well as we can and make up for London," said Jamie.
"We want to do really well in the doubles and we're both in the peaks of our careers.
