| mithro | yootis: I assume that _florent_ has | 00:07 |
| yootis | I assume so as well, but I also assume he's asleep :) | 00:08 |

| cr1901 | Heads up: If your amaranth directory- the one that litex uses- is a symlink to a copy of the amaranth repo, you may have trouble removing the old nmigen packages using pip 1/3 | 01:11 |
| cr1901 | If you do "pip uninstall nmigen" or similar, and get ".egg-links were moved" and/or "no files left to uninstall" | 01:12 |
| cr1901 | You need to remove the nmigen*.egg-links manually from /lib/python/site-packages/ and amaranth's source root | 01:13 |
| cr1901 | ditto for amaranth-soc,stdio,boards | 01:13 |
| cr1901 | Your nmigen imports should still work fine w/o a stale copy of the nmigen packages lying around | 01:13 |

| _florent_ | yootis: Just read your mail, the issue seems related to mmap, can you try to specify the length of BAR0 here instread of 0: | 08:08 |

| cr1901 | I've never tried... does the PCIe Xilinx stuff in principle work on Windows? | 16:29 |
| tnt | Xilinx provides a win driver for their pcie dma stuff. AFAIK. | 16:59 |

| SpaceCoaster | Snickerdoodle resurrected and bitstream built! https://github.com/enjoy-digital/litex/issues/601 | 21:16 |
| SpaceCoaster | I commented out i_USB0_VBUS_PWRFAULT = 0 in zynq7000/core.pay to get it to build. I am using a minimal zynq processing system block design, maybe too minimal. | 21:19 |
| SpaceCoaster | Snickerdoodle has no serial, switches, leds so a blank slate but the bitstream builds. | 21:20 |

| SpaceCoaster | It blinks! | 22:08 |
| yootis | _florent_ that doesn't help, the BAR size is 1M and setting it to 1M gives the same error. It is asking for 4026531848 bytes, which seems wrong. | 22:27 |
| tnt | yootis: does pcie comms work otherwise ? litepcie_util read the correct id string etc ? | 22:39 |
| yootis | yes | 22:39 |
| yootis | the only thing I can't get to work is litescope | 22:39 |
| yootis | Actually, maybe I'm nuts. I copied the docs where it says how to add the analyzer, but how does it know whether to connect it to PCIe or JTAG? | 23:20 |
