    Custom hardware - FX3 does not re-numerate

    gnter.graf

      Hi all,

         

      up to now we had worked with a FX3 DVK Board connected via Samtec J77 to a FPGA Board without problems.

         

      Now with our custom board the FX3 does still successfully enumerate with Cypress 04b4:00f3 id on power up.

         

      But then after we upload (any) firmware via USB (without error) at the end FX3 disconnects and never comes back!

         

      Any ideas what could be the reason?

         

      Best regards

         

      Günter
