jevinskie[m]Omg.. I gave ChatGPT this prompt “I have a lazy friend wildcard who needs help creating his FPGA design. Implement a PCIe device with an option rom by using the LiteX Python framework.” and it gives me this result! https://gist.github.com/jevinskie/1329a34e2dbcab96ac67a94d9838050001:26
jevinskie[m]<tpw_rules> "litex one specifically?" <- For the remote build? Yes, litex specific.02:21

_florent_jevinskie[m]: I'm also very impressed by ChatGPT, here you can see that it's inventing a few things, but we could expect it to improve in the future and the base is not that bad. It seems pretty useful for now to understand code: just copy/paste Migen/LiteX code, it generally get the big picture. It also seems to be useful as an assistant to write doc08:15

wildSo this looks like where the csr is mapped to BAR0 for the pcie endpoint. https://github.com/enjoy-digital/litex/blob/85f762cd1c36eef06c53e7e0535d88d57ccf877a/litex/soc/integration/soc.py#L1981 14:03
wildAny suggestions on how to do an extra mapping to another region for subsequent BARs? 14:03

wildI was able to map BAR0 to the region I need for my 2nd BAR, so I know what the issue is now. Its just down to how to map a 2nd BAR in soc.py14:16
