5 Downloading Firmware

The TSW14J58EVM has an Xilinx® Kintex® UltraScale® XCKU5P device that requires firmware to be downloaded every time power is cycled to operate. The firmware files needed are special .bin formatted files that are provided with the software package. The files used by the GUI currently reside in the directory called
C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\14J58 Details\Firmware.

To load a firmware, after the GUI has established connection, click the drop-down arrow on the right side of the Select ADC window in the top left of the GUI and select the device to evaluate, for example, ADC12DJ3200_JMODE0_2G_3G, as shown in Figure 5-1.

The GUI prompts the user to update the firmware for the ADC. Click "Yes”. The GUI will display the message "Downloading Firmware, Please Wait". The software now loads the firmware from the PC to the FPGA, a process that takes about 6 seconds. Once completed, the GUI reports an Interface Type in the lower right corner and LEDs D16, D17, DDR Calib and PLL lock should all turn white.

For information regarding the use of the TSW14J58EVM with a TI ADC or DAC JESD204C_B serial interface EVM, consult the High-Speed Data Converter Pro GUI User's Guide and the individual EVM User’s Guide, available on www.ti.com.

If the message appears as shown in Figure 5-2, verify that all jumpers are in the default position and the power and USB status LEDs are illuminated. If the 5.5-V power status LED is off, there may be a problem with the external power supply. Make sure this supply can source at least 5 A of current. If the available current is too low, this can prevent the firmware from downloading. Unplug and re-install the USB connectors and try to connect to the board. If this fails, cycle the power switch to re-initialize the power-up sequencer to try to correct this problem.
