FPGA and SoC SoM's can have fixed and user controlled Voltages for the I/O Banks. It is important to assure that the I/O Bank that controls the LED has a valid Supply Voltage applied.

| NOTE: Missing VCCIO Voltage will not cause AXI GPIO to freeze, no matter if it is connected to MicroBlaze or Zynq Processing Block. |

DONE LED
If there is on board LED directly connected to FPGA "DONE" output, then it is also possible to control it as long as it is possible to configure the FPGA (or PL portion of Zynq). For Zynq the PS subsystem is not needed if configuration is done via JTAG.
