I am trying to use an XEM6001 as a self powered device by removing R26.
The XEM6001 does power up and 3.3V is present on JP4, Front Panel does see the board but it will not load a configuration.
If I short the R26 pads while the external 3.3V is still applied Front Panel will load the configuration and the FPGA starts up. When I remove the short across the R26 pads while the external 3.3V is still applied the FPGA appears to loose its’ configuration.
The external 3.3V is rock solid.
Any ideas ?
