  1. Hi, I'm new to this forum so hopefully this has not been asked already. We have a system that contains an embedded Raspberry Pi 2 board and Xilinx FPGAs. We would like to be able to remotely debug FPGA issues. We have been looking into the Xilinx Virtual Cable (XVC) solution. This would allow us to connect Xilinx debugging tools like Chipscope to our FPGAs over an Ethernet connection. I have seen a few implementations where GPIOs from a Raspberry Pi connected to Xilinx FPGA JTAG signals and XVC server code running on the same Raspberry Pi allow for debugging FPGAs remotely. The code I have seen bit bangs the GPIO pins which seems very inefficient. I was wondering if Digilent has a solution where a Digilent USB to JTAG module is used for the Raspberry Pi to JTAG connection instead of GPIO pins to speed things up. If there was such a solution we would ship something like a JTAG-HS2 with all our systems so we could remotely fix problems at customer sites. Does Digilent have such a solution and if not do they supply Raspberry Pi software APIs that would allow customers to develop such a solution? I took a look at the Adept 2 stuff but that looks like it's targeted at configuring FPGAs. I don't think it's for integrating with Xilinx tools. I also looked at the "Digilent Plugin for Xilinx Tools" but I don't think there is a Raspberry Pi version of the plugin and I'm not sure if the plugin will work with XVC. Thanks in advance. RL
