ADS5562EVM: Firmware load error and Trigger (Ext / Soft) not Recognized

Part Number: ADS5562EVM
Other Parts Discussed in Thread: ADS5560, ADS5562

Hello,

I'm using a TSW1400EVM module with the ADS5562EVM with HSDC Pro v4.50. According to the documentation the default jumper settings on both boards allow for data capture using the HSDC software GUI, an external clock (i.e. 50Mhz @ 1.5Vpp) and an external trigger (voltage and duration information for the trigger has escaped me so I tried 1v to 2v @ 1us duration). The ADC SPI software is not required for basic capture correct?

I verified all default jumpers on the TSW1400EVM, and am supplying +5v to both boards so I don't beleive I need to change any jumpers on the ADS5562EVM, correct?

When I start HSDC, the serial number of the board is shown and I'm able to connect, no issue here. As expected it indicates no firmware loaded please select device and I select ADS5560_62. A download then appears to take place for a period of time, however when I would expect a "download complete" message I am again presented witht the no firmware detected please select a device message....

Having no clear option at this point I have tried to capture data with both exteral and software triggers but have not been sucessful - any hints what's going on?

    Hi,

    The ADS5562 EVM should just power up in a default configuration suitable for capturing data into the TSW1400 using HSDCPro.  You do not need to use the SPI GUI to program the EVM to anything in order for the EVM to work with the TSW1400.   You would only need the SPI GUI if you wished to use some feature of the ADC that is not available by way of jumper settings, such as setting a different gain setting or a test pattern output for debug. 

    It sounds like you are running into an issue with the TSW1400 and HSDCPro before getting to the point of capturing from the EVM.  A screenshot of your HSDCPro at this point would be helpful.  After you choose the ADS5560_62 device type the PC is pushing an FPGA firmware bit image into the TSW1400 FPGA which will persist in the FPGA until the TSW1400 is power cycled or a different bit file is pushed.  The HSDCPro in the lower right corner should display the name of the firmware that is resident in the FPGA, which should say ADC_FIRMWARE I believe.  If the HSDCPro does not display the firmware name, then something did not work.  Is your 5V supply to the TSW1400 rated for at least 3 amps of current?  If not, when the firmware download is complete but the supply is not capable of sourcing the current needed then the FPGA might not be able to hold its firmware.

    Regards,

    That did it!
    I was being too conservative and had the limit set to 1A

    Thanks for the quick response!
