4 Downloading Firmware

The TSW14J56EVM has an Altera Arria V GZ device that requires firmware to be downloaded every time power is cycled to operate. The firmware files needed are special .rbf 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\14J56revD Details\Firmware.

To load a firmware, after the GUI has established connection, click the “Select ADC” window in the top left of the GUI and select the device to evaluate, for example, ADS42JB69_LMF_421, as shown in Figure 7.

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 3 seconds. Once completed, the GUI reports an Interface Type in the lower right corner and the FPGA_CONF_DONE LED (D28) illuminates along with several of the status LEDs.

For information regarding the use of the TSW14J56EVM with a TI ADC or DAC JESD204B serial interface EVM, consult the High-Speed Data Converter Pro GUI User's Guide SLWU087 and the individual EVM User’s Guide, available on www.ti.com.

If the message appears as shown in Figure 8, verify that all jumpers are in the default position and all power status LEDs are illuminated. If certain jumpers are not installed in the proper location, the USB 3.0 Controller will not boot from flash memory. If any power status LED is off, there may be a problem with a power supply on the board, which can prevent the firmware from downloading. Unplug and re-install the USB connector 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.
