| sf-slack | <fahrenkrog> Hi all, Not being very familiar with OpenOCD, how do I modify the command below: ```openocd -f ${INSTALL_DIR}/${FPGA_FAM}/conda/envs/${FPGA_FAM}/share/openocd/scripts/board/digilent_arty.cfg -c "init; pld load 0 top.bit; exit"``` to permanently flash the SPI memory. Is that possible? Cheers, Alberto | 11:21 |
|---|---|---|
| sf-slack | <tmichalak> @fahrenkrog yes, it is possible to program the Flash memory from OpenOCD and then have the FPGA configured from there. Assuming you are using Digilent's ArtyA7(xc7a35t) you can do it like this: ```openocd -f prog/digilent_arty.cfg -c 'init; jtagspi_init 0 prog/bscan_spi_xc7a35t.bit; jtagspi_program {gateware/digilent_arty.bit} 0x0; exit'``` Now the `bscan_spi_xc7a35t` is a proxy bitstream that you can download from | 13:36 |

| sf-slack | <torsten.reuschel> Hi, I'm Torsten and currently work with Kintex7 on Digilent's Genesys2 board | 20:18 |
| mithro | Hi! | 20:19 |
| mithro | torsten.reuschel: The Genesys2 board is reasonably popular and I would love to see it supported by symbiflow-examples | 20:20 |
| mithro | torsten.reuschel: The Linux on LiteX project already supports the board (https://github.com/litex-hub/linux-on-litex-vexriscv), so it is just a matter of the open source tools supporting it | 20:21 |
| sf-slack | <torsten.reuschel> mithro: Right. I've got symbiflow ready and am able to build the example designs, e.g. counter_test. Next, I would go ahead and port the existing examples to Genesis2. Is that a sensible starting point? | 20:26 |
| mithro | I think so | 20:26 |
| mithro | I think mkurc started on some stuff in this area | 20:26 |
| sf-slack | <torsten.reuschel> I don't see a fork with that username on github | 20:28 |

| sf-slack | <torsten.reuschel> mithro: Will be in touch with mkurc. Diving into prjxray meanwhile. | 22:26 |
| mithro | torsten.ruschel: Kintex stuff should already be in prjxray - https://symbiflow.github.io/prjxray-db/kintex7/ | 22:38 |
| tpb | Title: X-Ray KINTEX7 Database (at symbiflow.github.io) | 22:38 |
| sf-slack | <torsten.reuschel> mithro: Kintex7 is generally available indeed, however, Genesys2 uses a larger package xc7k325tffg900. Thus far, I see only xc7k70tfbg676 in the database. | 22:45 |
| sf-slack | <torsten.reuschel> mithro: I managed to start running the fuzzers. We'll see how this goes. | 22:46 |
