T20 BGA256 Development Board with a demonstration design
that operates the LEDs. The board receives power through USB cable. Follow these steps to
run the design:
1.
Connect the 5 V DC power source or USB cable to the board and to your computer.
2.
Turn on the power switch (SW2). LED D105 (PWR OK) turns on, indicating that the
board is receiving power correctly.
Note:
The Trion

T20 BGA256 Development Kit does not include a DC power
adapter.
•
While configuration is in process, the configuration done LED D1 (CDONE) turns
OFF to indicate the device is in configuration mode.
•
At the same time, the LED D2 (NSTATUS) turns ON to indicate there is no
configuration error.
•
When configuration completes, the configuration done LED (D1) turns on again. Four
green LEDs (D3 - D10) turn on, sweeping from D3 to D10 in ascending order.
Note:
If LED D105 does not turn off, the board is not receiving power correctly.

D7, and D9) and group 2 (D4, D6, D8, and D10).
