EEPROMs with Digilent license for JTAG with FT2232
JColvin replied to Quemar's topic in Sales Questions
Hi @Yingda, I have sent you a PM. Thanks, JColvin -
Hi @anshumantech, Steps were taken to prevent any cross signal problems. I've also tested this with a JTAG HS3 individually wired to J8 while also having a USB cable directly connected to the USB-UART port, and the Vivado software (as well as Digilent's Adept software) will only allow a single connection to the FPGA at a time. Thanks, JColvin

Hi @anshumantech, It is using a FT2232HQ as per the Arty A7 Reference Manual: https://reference.digilentinc.com/reference/programmable-logic/arty-a7/reference-manual#usb-uart_bridge_serial_port. Thanks, JColvin

Hello @Dm77, I have sent you a PM about this. Thanks, JColvin

Hi @NemotoFutoshi, The 12 MHz clock comes from a 12 MHz oscillator that is powered by the 3.3V power rail; it's on that missing page of the public version of the schematic. The Cora board can be used as a USB host through Linux, though the number of examples demonstrating this are fairly limited. Thanks, JColvin

Hello, This is also detailed a little bit more in our Getting Started with Vivado IP Integrator and Vitis guide in this section here. Thanks, JColvin

Hi @anshumantech, Yes, you should be able to use the Digilent JTAG modules and use the Integrated Logic Analyzer in Vivado. The JTAG HS1 and JTAG HS2 should be able to connect directly (via a 6-pin connector) to the JTAG connector between the JB and JC Pmod ports. The JTAG HS3 can also connect through the same port though you'll need to individually wire the appropriate signals to the Arty A7. Thanks, JColvin

Welcome to the Forums @ProfRob!

Hi @Iceman2020, ...So I did. I have updated the original posting (direct link to post). For my own personal curiosity, what are the Statements of Volatility needed for? The only non-volatile memory that users should typically interact with is the flash memory, but that can be easily over-written with a different board configuration or erased entirely, and messing with the EEPROM usually results in bricking the board such that it can't be recognized by the Xilinx software and can no longer be configured. If a known working configuration is needed, there are a number of examples including the out-of-box designs available on the Digilent GitHub (link). Thanks, JColvin

Hi @maz, I have moved your question to a more appropriate section of the forum. Based on what you have said you have tried, I believe you have done all of the troubleshooting steps that I would normally recommend. The engineer much more familiar with the WaveForms software and the Analog Discovery 2 who regularly checks this forum may have some alternate steps that you can try. Looking at the screenshots, I presume you/your co-worker are using Windows 10? Thanks, JColvin

About ZedBoard FMC Pcam Adapter and zedboard
JColvin replied to Paul Chang's question in Add-on Boards
Hi @Paul Chang, I have reached out to ask about this; it looks like that other DDR chip on the newer Zedboard has a slightly different memory configuration than is normally present. From what I can tell, the newer board is supposed to have the same memory configuration 16 Meg x 16 width x 8 banks, but FGBA code is indicating the DDR chip would have a 32 Meg x 16 width x 8 banks. I don't have one of these newer boards so I can't test this out for myself though. Thanks, JColvin -
Hi @aivark6, I have sent you a PM about this. Thanks, JColvin

Hi @zygot, I have asked for the FPGA product manager for their input on this. Thank you, JColvin
-
Hi @Iceman2020, You are correct. I have edited the original posting to now contain this correction. Thank you, JColvin
-
Hi @Ralph Kruger, Which board do you have? Thanks, JColvin

Hi @Iceman2020, I apologize for the delay, it look longer than expected. I have attached the two pdfs. Let me know if you have any questions. Thanks, JColvin Statement of Volatility Cmod A7-35T.pdf Statement of Volatility Cmod A7-15T.pdf

Hi @fkropat, I have sent you a message as well with the Digilent contact information. Thanks, JColvin

Hi @borhan, What board are you using so I can help you restore the material? As for preventing the problem in the future, the only recommendation I have would be to maintain extra caution when configuring different FTDI devices with FTProg or other similar programmers as they, as you and many others have found out, can very easily overwrite the configuration on a different board and not everything is easily reconfigured. It's an extra step in the process, but I would disconnect boards that you don't intend to program when using these types of programmers to prevent accidents. Thanks, JColvin

Hi @Tim S., Thank you for sharing this project! Do you mind if we link to this post as a community project on different Digilent Wiki pages, such as on the Zybo Z7-20 and Arty A7 Resource Centers? Thanks, JColvin

Hi @GreenbackBoogie, I have sent you a PM about this. Thanks, JColvin

Hi @Iceman2020, I ask for these materials for you. Thanks, JColvin

Hi @KKING, Not at this time. For your own reference, this is the text that I proposed (with an additional blurb in the physical interface section towards the beginning of the topic) for the type 6A expanded I2C. Thanks, JColvin
-
Hi @KKING, I apologize for the delay. It was agreed that we can add in a new section for the expanded Type 6 (I2C). I have written the new wording for the documentation and am waiting to get feedback/approval from the interested parties. Thank you, JColvin

Hi @JerryG, The main reason that we don't simply provide the application is because like FTProg, the Digilent application is similarly dangerous in that it can very easily overwrite other devices that might be attached to your computer and those devices might not be so easy to recover. In theory, we could post detailed instructions on how to use the application, but considering the number of accidents that still happen as evidenced by the posts on the Digilent forum alone, we feel that it is a better practice in the grand scheme of things to only distribute the application on a need basis. Thanks, JColvin

Hi @lukowo, What board are you using? Thanks, JColvin
