11:30 <tpb> Title: Add de10 nano board by sajattack · Pull Request #39 · litex-hub/litex-boards · GitHub (at github.com)

11:36 <Claude> hello

11:37 <sajattack> o/

11:40 <Claude> not sure if this is the right place to ask, but i have a bit of trouble running litex. i did the install accoring to the readme (./litex_setup.py init install --user) , on a debian 9.9 system. as far as i can tell all depencies are met. still after the install, which runs trough without any error, i get an error when i run e.g. the litex-boards ulx3s target. i get the error "ImportError: No module named

11:40 <Claude> 'litex_boards.official.platforms.ulx3s'"

11:41 <sajattack> I'm just as much a noob as you are, but I think maybe litex_boards is separate?

11:41 <Claude> is there anywhere some more documentation than the small readme ? :)

11:41 <sajattack> https://github.com/litex-hub/litex-boards try the setup.py here

11:42 <sajattack> idk, I just showed up here because I was trying to port a new board

11:43 <Claude> ahhh ok good hint , get an permission error when running it manually. will look into it. thanks

11:43 <Claude> sajattack: ah yeah exactly the same for me :) brining up a ecp5 board at the moment. now ddr3 its on the list :)

11:43 <sajattack> code is documentation :P

11:43 <sajattack> sudo it?

11:44 <sajattack> do you know how a board is supposed to behave when you flash basesoc?

11:44 <sajattack> I got uart echoback and no idea if that's right

11:45 <sajattack> also need to learn how to add ddr3 at some point I think

11:45 <Claude> hm no not really. so far i just had the prjtrellis attosoc example ported over to my board and did most of the bringup with that

11:45 <sajattack> ok

11:46 <sajattack> I copied the de0nano and modified until I had de10nano

11:46 <sajattack> but no idea if I did it right lol

11:46 <sajattack> one major difference is no sdram

11:47 <sajattack> and when I try linux-on-litex-vexriscv, I get an error in the dts about no main_ram key

11:47 <sajattack> so I think that's related

11:48 <sajattack> but at least my build passes for the board def and I get uart echo

11:57 <Claude> no luck with sudo

12:23 <_florent_> Hi sajattack, Claude

12:23 <Claude> hi _florent_

12:23 <_florent_> thanks @sajattack for the board support, i'll review it soon

12:24 <_florent_> @Claude have you been able to revolve your issue?

12:24 <Claude> _florent_: so far not

12:26 <_florent_> it should work following https://github.com/enjoy-digital/litex#quick-start-guide-for-advanced-users

12:26 <tpb> Title: GitHub - enjoy-digital/litex: Build your hardware, easily! (at github.com)

12:27 <_florent_> if you go to litex/boards/targets are you able to build one of the target there?

12:31 <Claude> _florent_: sorry was afk

12:32 <Claude> yes this i did. the install to --user , running e.g. the ulx3s target

12:36 <_florent_> can you try to do: ./litex_setup.py init and then sudo ./litex_setup install?

12:36 <_florent_> if it's not working, please post the install logs here to try to understand

12:39 <Claude> _florent_: didn't worked

12:41 <Claude> the log

12:57 <_florent_> ok thanks, is it the same if you do sudo ./litex_setup.py install?

12:58 <Claude> _florent_: yes

12:58 <Claude> actually it was with sudo installing it

13:04 <_florent_> ok, and just to see if it's an issue with litex or litex-boards, can you try to build one of the targets directly in litex: "cd litex/litex/boards/targets" and "./ulx3s.py --gateware-toolchain=trellis "for example

13:07 <Claude> _florent_: ah wait a minute. need to install the risc-v gcc first

13:12 <Claude> _florent_: ok this went trough

13:13 <_florent_> ok, so LiteX and the cores are installed correctly, the issue you had seems specific to litex-boards

13:34 <Claude> _florent_: thank you very much for the support

13:37 <_florent_> Claude: happy you got it working, are you trying to add support for the colorlight board in SODIMM form factor you reversed?

13:40 <Claude> _florent_: hah :) no not yet , bringup of my own ecp5 board . This weekend is ddr3 time https://usercontent.irccloud-cdn.com/file/q8s2PaVY/irccloudcapture8546153713907761825.jpg

13:41 <_florent_> Ah ok nice

13:42 <_florent_> You can look at the Versa ECP5 or OrangeCrab for some inspiration

13:44 <Claude> currently cloning the orangeCrab ddr3 test :)

13:46 <Claude> perfect that builds , i can adjust for my board

15:53 <Claude> _florent_: yipieeee!

15:53 <Claude> ups! sorry for spam, should have come trough as pastebin

16:43 <_florent_> Claude: great, that was fast :)

16:48 <Claude> thanks, i'm totally blown away btw :) this all is by far the most pleasant fpga expirence since a very long time for me

21:48 <rvense> Claude: is that... an ecp5 in a pcmcia card!?

21:51 <Claude> Yes

21:51 <rvense> very cool. do you have a particular usage in mind?

21:59 <Claude> Heh yes , actually it's a Amiga gfx card

22:05 <rvense> ah, the bus is fast enough for that?

22:57 <sajattack> so can anyone confirm if the default soc in litex-boards is supposed to echo serial?

23:01 <Claude> It did in my case sajattack

23:02 <sajattack> cool

23:02 <sajattack> did you figure out ddr3?

23:03 <Claude> rvense: its not much bandwidth (from the Amiga CPU to pcmcia it's just 9mbyte/s) , but for the usual amiga-ish stuff it's plenty

23:30 <sajattack> Claude: did you figure out how to set up ddr3?
