Hello FPGA community, I am a beginner without prior knowledge of either FPGA or Python. I understand the advantage of PYNQ as an excellent way for rapid prototyping without requiring much knowledge about FPGA - Python API abstraction makes the process resemble microcontroller programming. However, I would like to learn FPGA in a traditional way with well-established toolchain and workflow used in industry (Verilog, Vivado, Xilinx’s WebPACK…etc). So leaning Python, Jupyter, notebook…etc is not a priority at the moment. Will a PYNQ board (e.g. Z1) be a good starting point? and if it is, are there any tutorials or material to get me started besides the official PYNQ toolchain and workflow? Your input will be much appreciated.
Hi there, I bought a PYNQ-Z1 board near the end of 2017, and every weekend I was enjoying it on jupyter notebook (only with base overlay. I'm a newbie to FPGA and still learning how to design it.) Last night it suddenly turned off all LEDs silently while the power was ON. I slided the power switch to ON/OFF, changed the power supply from microUSB (tried both from PC and from 12V3A adaptor) to regulator (12V 3A), but no LEDs lit on the board. It wasn't the first time since I bought the board that it seemed to go wrong; it was at the middle of last month that the board started repeating abrupt reboots every a few or tens of minutes. I thought it was because I had updated last month the system on microSD to PYNQ2.0. Until then I had been using the microSD I bought with the board (maybe PYNQ1.4 or something) A few days ago I noticed that the older versions of PYNQ system images are still available on the server, so I decided to downgrade it, and prepared a microSD with older version of PYNQ. But last night the board went dead before I try it. Could someone tell me how to fix this problem? Or is it possible to ask Digilent Inc. to repair the board? Kind regards, naoya
Hello: I am trying to get PYNQ onto the Arty Z7-20 by following the steps from this tutorial: https://projects.digilentinc.com/90432/programming-python-on-zynq-fpga-ec4712. I've burned the PYNQ Z1 2.6.0 ISO file (latest version) to a microSD card, but when I go to boot from the SD Card I only get the red LD13, TX/RX, and Ethernet lights to turn on. The six LED's at the bottom do not turn on as well as the done LED to signify the bitstream has been loaded. I switched the booting from to QSPI to shelve the microSD issues, but even after all the appropriate LED's turn on I'm not able to log into the board using a terminal window (I've tried Tera Term and PuTTY). When I drop down the ports I get two USB Serial Ports that show up but neither is a virtual COM port that I have read is necessary to communicate with the UART bridge on the board. I've downloaded drivers from STMicroelectronics for the VCP as well as some from FTDI for the UART bridge but neither seemed to make a difference. Any help or tips would be much appreciated, thank you. Hunter
