  1. Hi, We are designing our custom pcb and taking arty-7 35 for reference. We have purchased JTAG HS2 cable and connected this to J8 connector of arty-7 35T FPGA. We have given power supply using adaptor. We are able to program arty7-35 in vivado hardware manager with both .bin and .bit file by changing jumpers for configuration type. We are following arty-7 programming guide for flash memory configuration. Our doubt is will these steps works if we design our custom PCB with same sets of components? Apart from that is there any dependacy of J8 connector with digilent proprietary USB JTAG circuit?
  2. Dear All, I have worked on Arty-7 and Nexys Video Devlopment board. Each board has PHY from different Vendor RealTek (Nexys Video) and Texas Instruments (Arty7). I have following doubts regarding the same. If my requirement of speed is in between 8 mbps to 30 mbps. What will be effect on Power consumption in case of Realtek PHY and Texas Instruments PHY. Real Tek PHY in Nexys Video works on 125 MHz while Texas Instruments PHY works on 25 MHz. Currently we are using Development board but If i make my board/PCB, does fresh PHY IC required any pre-configuration? I have seen datasheet which shows about some registers configuration. For Functional verification : In case of Realtek PHY, we are sending Tx clock with Data from FPGA MAC while in case of Texas Instruments PHY, Both TX and RX clock coming from PHY itself which sometimes makes Functional verification tricky
  3. FIrst of All Yes, We have requirement of UDP Packets for both Transmit and Receive. Something like I want to send command from PC to FPGA after that it will start sending UDP packets. (For Example: I will send command to start video from PC to FPGA then I will send UDP Packets of Pixels data from FPGA) One more thing is i am looking for is only single point communication between PC to FPGA. No network switches in between (No multi-FPGA or any cluster ) @zygot : It will be great help if you have any example for FPGA Implementation with soft-processor like micro-blaze. Currently I am using Nexys-Video which supports Microblaze. We have implemented Gigabit Tx by @Hamster in verilog and we are able to transmit data and we can visualize all packets on wire sharks. Now, we would like to learn how to communicate from PC to FPGA but not able to find proper examples.
  4. Thank you @jpeyron for support. We would like design custom board similar configuration modes to Arty A7-35 which has only JTAG-USB and SPI Flash Memory.
  5. Currently we are using Nexys Video Development Board which is having many features and peripherals. Now we want to make our custom board with limited peripherals. We would like to use only 2 Configuration modes - JTAG Progamming and Quad-SPI Flash Memory Mode. We are not looking for SD Card and USB Programming mode. In Reference Manual Configuration Diagram, There is one PIC14 Controller available, We have confusion about is requirement? Is it necessary to have if we are not using SD Card and USB Progamming mode? It will be great help if you can direct us in this regard. We are not able to find technical support email address hence we are writing on this email address.
  6. Hello, Jpeyron Yes, I have implemented Gigabit Tx by @Hamster in Both VHDL and Verilog. This is only for transmission from FPGA to PC Can you Help us for Receive part from PC to FPGA? How to begin communication from PC to FPGA. I want to send some commands using UDP from PC to FPGA. It will be great help
  7. Hello All, I am currently working on Nexys Video Ethernet. I want to transmit and recieve UDP packets between PC and Nexys Video FPGA . Is it possible to perform without Microblaze? How to send UDP Packets from PC to FPGA.?
