14:47 <mithro> FYI There is a CHIPS Alliance workshop starting in 13 minutes at https://chipsalliance.org/workshops-meetings/

16:07 <mithro> @acomodi: The new base Kokoro image has been created and hopefully will be used on https://github.com/SymbiFlow/symbiflow-arch-defs/pull/2112

16:18 <sf-slack> <krutideepan123> Hi everyone, I am Kruti Deepan Panda a 2nd year Electronics and Communication Student. I know verilog and have made a simple microprocessor based on a series of lectures by MIT's OCW. I would love to help out here. Is there any way I can contribute to this project.

17:25 <tcal> @gatecat: holy @#%$@, it works! LiteX on LIFCL-17 is alive with the latest nexpnr updates!

17:25 <gatecat> Yay!

17:25 <gatecat> That's very good news

17:25 <tcal> It certainly is

17:26 <gatecat> Thanks for your help testing!

17:28 <tcal> I'm amazed how you can debug stuff without HW! And jumping straight from blinky to LiteX :)

17:30 <tcal> I have it running at 75MHz (nextpnr meets timing with 88.5MHz given the right seed); it would be great if we could get it up to 112.5MHz (we have integer divisors of 450MHz). I can start looking at critical paths and see if there's anything obvious that Yosys could be doing better for Nexus.

17:30 <gatecat> One thing to try is doing Yosys synthesis and Radiant PnR - there should be a LiteX option for this

17:31 <gatecat> This helps work out whether the timing problem is more on the Yosys or nextpnr side

17:31 <gatecat> and yeah comparing critical paths between the flows would be interesting too

17:35 <tcal> 👍

17:48 <sf-slack> <pgielda> cool !

22:05 <sf-slack> <fdeweers> I'm trying to setup the open source toolchain for my zturn board (zynq 7020). I'm getting a uboot error however when I reset the board. `Type [C-a] [C-h] to see available commands` `Terminal ready` `���渝���` `U-Boot SPL 2019.01-g3ccf78ee (Dec 17 2020 - 17:03:21 +0000)` `mmc boot` `Trying to boot from MMC1` `MMC: no card present` `spl: mmc init failed with error: -123` `SPL: failed to boot from

22:05 <sf-slack> all boot devices` `### ERROR ### Please RESET the board ###` Am i doing something wrong or is this related to the uboot files from the setup guide?

22:23 <mithro> gatecat / tcal: Massive congratulations!
