| _florent_ | yes, what's your issue? | 12:35 |
| tnt | _florent_: https://github.com/enjoy-digital/litepcie/issues/125 | 12:37 |
| tnt | Something is wrong with DMAReader (well it's not in DMAReader, it's in the phy) since the cleanup. | 12:38 |
| _florent_ | Thanks, I'll check to see what is different from the build I do/configuration I used. | 12:41 |
| tnt | I'm in x8 gen 3.0 | 12:42 |
| tnt | I'm trying to inspect the pcie_support thing now, But not sure how to add verilog signals to litescope yet | 12:42 |
| _florent_ | x8 gen3.0 is also what I've been building recently | 12:45 |

| _florent_ | Are you on Ultrascale or Ultrascale+? | 12:46 |
| tnt | Ultrascale+ | 12:46 |
| tnt | ZynqMP EG11 | 12:46 |
| *** benh <[email protected]> has joined #litex | 12:47 | |
| _florent_ | OK, so same also | 12:47 |
| _florent_ | Can you share the LitePCIe integration code? | 12:52 |
| _florent_ | I'll do a test on hardware with a configuration as close as possible to yours | 12:52 |
| tnt | https://pastebin.com/860bE6Jz | 12:54 |
| tpb | Title: self.pcie_phy = USPPCIEPHY(platform, platform.request("pcie_x8"), - Pastebin.com (at pastebin.com) | 12:54 |
| tnt | and then I just have some test module connected to dma0. | 12:54 |
| tnt | Is there a way to tap verilog signals ? | 13:02 |

| tnt | _florent_: any luck in reproducing the issue ? | 14:42 |
| tnt | _florent_: tkeep is defined as data_width/8 but in the doc it's data_width/32 (and the old code seems to indeed use data_width/32) ? | 15:53 |

| tnt | _florent_: This seems suspicious to me : "AXISTEN_IF_RC_STRADDLE" : True, | 16:33 |
| tnt | _florent_: confirmed that was the problem. | 16:41 |
| _florent_ | @tnt sorry, had to do something else. Good catch thanks! | 17:13 |
| _florent_ | In the projects I'm testing more regularly, I'm using an generated .xci, so wasn't having the issue... | 17:16 |
| _florent_ | Sorry for the typo when simplifyng the Ultrascale(+) support and thanks a lot for the feedback/fix! | 17:18 |
| tnt | _florent_: well ... all isn't fixed :/ | 18:28 |
| tnt | This only fixed up to 76c7381ad8d7eab01020fd9bbe0249166535f2a8 (the cleanup). | 18:29 |
| tnt | But going to master it fails again :/ | 18:29 |
