Download Flow
1.
SRAM: Scan the device and download bitstream after power on. When
Done is on, it indicates it is successful.
2.
Internal Flash: Power on and download. After downloading the
bitstream file successfully, it can power down to reset and load the bit
file from the internal Flash. When the Done is on, it indicates that the

Overview
The development board is powered via a power adapter. The input
parameter is 100-240V~50/60MHz 0.8A, and the output is DC +5V 2A.
DK_START_GW1NZ-LV1FN32C6I5_V3.1 development board uses
LDO power supply chip to step down voltage from 5V to 3.3V, 1.8V, and
0.9V. The power supply current can support up to 2A. The input voltage is
5V, which can meet the required power of the development board.
