likewiseIs it correct the litex-boards/litex_boards/platforms/*.py files do not have the executable flag?08:21
likewiseProblem I have with the quick start is nothing happens when I run: python ./xilinx_alveo_u250.py08:33
_franck_likewise: platform files are meant to be used by target files (or your own file)08:49

likewiseDoes Litex support building an SoC as a stand-alone (set of) Verilog source(s), i.e. for re-use in RTL projects? I am interested in building a VexRiscv with AXI4 Crossbar and a AXI->AXI4Lite converter with AXI4 Lite cross bar. I could use some help, if anyone is interested in a code bounty, let me know.12:50

_florent_likewise: That's one of the next task/priority in my todo list :): Create a generator to generate the SoC as a standalone core (as we are already doing with LiteDRAM/LiteEth, etc...)18:23

_florent_to generate a standalone verilog core similar to this ^18:26
_florent_the user will be able to customize it with most of the parameters exposed on targets (and probably some others). I should start this next week and could be interested to have someone testing it and providing feedback18:29

cr1901_florent_: If you decide to use a different HDL going forward, does that mean LiteX will support two different (or more!) languages, or will the cores be rewritten to a single HDL eventually?21:44
_florent_cr1901: 1) first experiment/mature it on a new/independent design 2) offer a full Migen/LiteX compatibility layer and test it on actual LiteX design 3) Switch progressively :)22:51
shorneah, I just spend a week (hour here, hour there) trying to figure out why my platform is unstables, kernel crashing in a very strange spot that makes no sense23:41
shorneI tried bisecting the kernel, toolchain, litex, what else!23:42
shorneFinally I remembered (and doing some git reflog snooping) I updated the mor1kx core earlier this month, it turns some changes we did last year for formal verification I haven't been running with.. it seems that broke something23:43
shornerolling back mor1kx to around 2021 Feb fixed the instabilities23:44
