1. Select power source:

• For PCIe power supply, put the jumper on the left position.
• For External supply via jack CN4, put the jumper on the right position. Input voltage: 5V to 15V max.

When the power supply is stable, the LED LD4 will be red.

2. Select Boot mode (R01 only)

SW2 selects the FPGA bootmode. Set it to Master SPI:

• 1: ON
• 2: OFF
• 3: OFF

Once booted, FPGA prog done LED LD3 will be green.
