cr1901_modernmithro: From what I can tell, riscv has only been tested up to the BIOS prompt.07:56
cr1901_modern(Sorry I fell asleep _hard_. Awake now.)07:56
mithrocr1901_modern: I was sure it had been tested before...07:57
cr1901_modernmithro: Well... mmicko got it working on ice40. So there's "prior art" for it working.08:01
cr1901_modernIt just doesn't work w/ our set of gateware :P08:01
cr1901_modernmithro: Adding lm32 fupy to icebreaker as a "sanity" check now08:17
cr1901_modernI imagine you'll be asleep within the hour :P08:17
cr1901_modernmithro: Well, I'll just leave a PR and you can merge when you get the chance. I'm going back to riscv fupy once icebreaker has been added in.08:19

daveshah_florent_: playing about trying to get the ULX3S demo to build. But for some reason LiteX is trying to use system gcc rather than lm32-elf-gcc12:05
daveshahI am seeing "as: unrecognized option '-mmultiply-enabled'"12:05
daveshahah, nvm12:21
daveshahI had managed to install binutils in /usr and gcc in /usr/local12:21
daveshahreinstalling binutils in /usr/local fixed it12:21
tpbTitle: Switch Trellis build to use LPF constraints; working on ULX3S by daveshah1 · Pull Request #122 · enjoy-digital/litex · GitHub (at
daveshahULX3S does now get to the LiteX BIOS, need to work on the SDRAM now12:35

cr1901_moderncc: esden13:08
cr1901_modernThis was the quickest port yet LOL. Took me less than an hour from creating a new file to micropython boot.13:08

daveshahAh, seems the ULX3S SDRAM clock wasn't connected. Let's see if connecting it fixes things...13:28
daveshahGetting a lot closer now13:34
daveshahMemtest data failed: 823/524288 errors13:34
daveshahMemtest addr failed: 14/8192 errors13:34
daveshahMemory initialization failed13:34
daveshahProbably just need to tweak the dodgy lut-phase-shifter13:35
_florent_daveshah: thanks for testing/fixing, yes with the results you have it's probably related to the phase shift13:50
daveshah_florent_: removing the phase shifter altogether and it's almost 100% failure, so yes it's definitely related13:51
daveshahseeing a similar error rate with 10 LUTs in the shifter13:51
daveshahmight just have to wait until PLLs are supported, shouldn't be too long anyway13:52
_florent_daveshah: yes we want wait PLL support13:54
_florent_daveshah: is LPF already integrated in Trellis btw?13:55
daveshah_florent_: it's an open PR13:55
daveshahawaiting review, should be merged by the end of today13:55
