I have been working on this for quite some time and I am unable to get my custom board working. When I attach my board through the development board I get the message "No devices have been detected."
My custom board is .4mm thick if it matters.
C1 - C4 CL05A105MQ5NNNC
Crystal - 7M-16.000MEEQ-T
Inductor - CV201210-2R2K
I think the most likely area of problem would be around C3 and C4 with the meander line. This is a pretty simple design and I'm not sure where else to check.
I have tried both the newest version of JTAG and the one recommended by SmartSnippets Studio.
