Thanks for the reply I have the following configuration: JP1 connected to VCC and int JP2 & JP3 have jumpers on them JP4- JP9 all have a jumper connecting pins 2&3 or connected to JTAG Could the problem lie with the J5 jumpers? The description says its for external power so when I have the jumper between VCC & GND I get a message saying I need a firmware update but it never updates. Between GND & GND gives the same cannot connect message. Any Suggestions to fix this?
