Is it possible to write a VERILOG / VHDL code to download the programming file (fpga bitstream) to the hardware device (for example an SPI flash memory)? I'm asking this, because I would like to transfer a bit stream into a spi flash memory, which will then be mounted on an fpga card for boot and configuration. I have already written a few lines of code to write, read, and erase the contents of the 32 MB NOR flash memory (PMODSF3). I tested my code and it works without problems! However, how to read the bitstream, before writing it to the flash memory? Do I only need to transfer the bitstream into flash memory or do I have to add a header and a footer in the memory before and after the transfer of the bitstream file? Have you ever worked on a similar project? N.B: I am using a Xilinx FPGA (Artix-7) on a customized board. I would like to find an alternative solution to the Xilinx hardware manager to program the SPI flash. Any ideas, feedbacks and suggestions are welcomed! Thank you Hervé
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?
Hello , I am using VIVADO 2018.2 HLx editions (Windows) Do you have the steps required program the Digilent ARTY Z7 -20 SPI flash with a standalone FPGA design? I have followed a number of web examples that claim to show the route to follow none of which work. They are either incomplete or for the wrong version of ARTY , VIVADO and SDK. Thanks
What version of Vivado was used to create the tutorial "How To Store Your SDK Project in SPI Flash"?
