<lkcl> _florent_, something like this?
<tpb> Title: git.libre-soc.org Git - pythondata-cpu-libresoc.git/summary (at git.libre-soc.org)
<lkcl> i based it on vexrisc principle due to the massive source code size (130,000 lines of nmigen across multiple repositories)

<lkcl> we use JTAG TAP (by Chips4Makers) in Libre-SOC, and it's very handy to connect to a running simulation using jtagremote
<lkcl> this is a patch which enables jtagremote, and adds a new option --with-jtagremote to the litex sim.py
<chmouss> I'm trying to get etherbone to work on the Versa5G (lattice_versa_ecp5.py --with-etherbone --build). So far, the ping is OK, but litex_server can't connect.
<chmouss> Anyone had etherbone working on this board?
<lkcl> that looks like quite a lot of options.
<lkcl> what options did you give?
pftbest has quit [Remote host closed the connection]
<chmouss> lkcl: basically litex_server --udp
<chmouss> I also gave the --udp-scan option a shot (did not find any etherbone); and also wishbone-toola shot: no luck
<lkcl> chmouss, can i recommend running tcpdump (or wireshark)?
<lkcl> see what's actually going on, whether there's traffic in/out
<_florent_> chmouss: Hi, IIRC I tested it recently on the Versa ECP5, but could do another test tomorrow
<_florent_> chmouss: Are you using up to date LiteX?
<_florent_> chmouss: before this, the UDP/IP core was not running in the right clock domain due to a regression and required a sys_clk >= 125MHz

<chmouss> _florent_: I tried both the 2020.12 and master revisions; I can see that the timings are muich harder to close on master but same behaviour for either revisions
<chmouss> I'm using trellis though, not sure if it could have an impact
<_florent_> chmouss: OK, I'll do a test tomorrow
<chmouss> bty, I also had the same behaviour with a RMII 100Mbps PHY, ping OK pour etherbone don't respond
<chmouss> I can send you the wireshark traces if you wish
<_florent_> chmouss: I'll first do a test and will share the bistream with you if working on my side.
<chmouss> thanks!
