Hi PeterVH
I really appreciate your effort on helping us with this issue with Leonardo boards. Thank you!
I will try your solution as soon as I get home. The process you described is very clear, but even though there is a photo of the assembly in your blog I'm not very sure about how the MISO/MOSI and SCK pins should be connected to the ICSP header of the Leonardo. I would be very grateful if you could clarify it to me.
Thank you in advance!
