| ricos | daveshah I'm trying to run a blinky led on a zynq xc7z020clg484-1 but it crashes with: https://pastebin.com/C0pqLRvK . Running the same code with an artix works fine. | 10:39 |

| daveshah | ricos: what is the backtrack? | 10:40 |

| daveshah | ricos: hmm, no idea, if you provide a test case I'll have a look at some point but it might be a few days | 10:45 |
| daveshah | just to check, is the device database as recent as the nextpnr binary? | 10:47 |
| *** proteus-guy has joined #symbiflow | 10:49 | |
| ricos | daveshah, it should be ... | 10:49 |
| daveshah | that should all be fine then | 10:50 |
| ricos | nextpnr-xilinx -- Next Generation Place and Route (Version a9df1d5e) | 10:50 |
| ricos | where could I check the device database? | 10:52 |
| daveshah | if you built it at the same time as building nextpnr then that will be fine | 10:52 |
| ricos | yes | 10:52 |
| daveshah | then please provide a JSON & xdc and I'll look further | 10:57 |
| ricos | daveshah, https://tmpfiles.org/download/51038/archiv.tar | 11:03 |
| tpb | Title: /tmp/files - Temporary File Hosting (at tmpfiles.org) | 11:03 |
| daveshah | thanks | 11:03 |
| ricos | daveshah, in your example (artyz7 https://github.com/daveshah1/nextpnr-xilinx/blob/xilinx-upstream/xilinx/examples/artyz7-20/blinky.sh) you use a xc7z020clg400 . Is there an easy way to get the database for this chip? | 11:06 |
| tpb | Title: nextpnr-xilinx/blinky.sh at xilinx-upstream · daveshah1/nextpnr-xilinx · GitHub (at github.com) | 11:06 |
| daveshah | ricos: I created it manually a while ago | 11:06 |
| daveshah | but that was a hack and I can't remember the exact steps | 11:07 |
| daveshah | one of the xray people (litghost?) will be online later and can help | 11:07 |
| ricos | ok... thanks for your help | 11:08 |
| daveshah | ricos: the problem is that T2 is one of the Zynq special purpose ways | 11:12 |
| daveshah | *special purpose IO | 11:12 |
| daveshah | it's failing in a horrible way and I'll add it to my todo list to fix (this kind of issue is why nextpnr-xilinx isn't close to end-user ready yet unfortunately) | 11:12 |
| daveshah | but you would need to use a pin that is connected to the FPGA fabric (ideally a clock input) for the clock | 11:13 |
| ricos | daveshah, thanks, using another pin works as expected | 11:22 |
