FX3 JTAG connection between J-Link connector and FX3 DVK (CYUSB3KIT-001) schematic

[NaMo_1534561]

Hello,

In the J-LINK/J-Trace JTAG pinout arrangement, pin #2 is NC(Not connected), but in the circuit schematic of FX3 DVK(CYUSB3KIT-001) it is connected to VIO5.

Which definition should I follow?

Hi Morimoto-san,

In the pin-description for J-LINK 20-pin connector, it is mentioned that pin#2 can be connected to VDD or left open in the target system.

So, you can connect pin#2 to either VDD or leave it open in your design.
