TSW14J50EVM: Unable to Program TSW14J56 Board

Part Number: TSW14J50EVM

Tool/software:

Hello,

I have been working with the TSW14J56 board for the past two years without any issues. However, for the past two days, I have been unable to program the board. I am encountering the following errors:

The following image shows the leds on the TSW14J56

Please assist in resolving the issues. 

Thank you

  • Hi Vandana,

    What is the current setting on the power supply connected to the J56.

    Please make sure it is 12V, 4A.

  • Hi Rob,

    Thank you for the reply.  we are using Mean Well GST60A series is a 5V, 6A supply as recommended by TI. We have another unit tsw14j56 which is working fine without any issues using the same power supply.

  • Hi Vandana,

    Typically the FPGA won't program or won't program properly if the current limit on the power supply is not set high enough.

    If you have another J56 data capture board working with your current power supply, then there might be a USB connection issue.

    Can you connect directly into the PC. Don't use a USB hub?

    Any damage to the J56 board? Might be good to check and see under a microscope.

    Unfortunately, that is about all I can offer. The J56 is obsoleted and we cannot get any more of these boards assembled as the FPGA is obsoleted.

    Regards,

  • Hi Rob,

    Sure. We will look into the power issues and USB cable connections.

    Thank you
