has anyone managed to build a versa_ecp5 SoC with working Ethernet recently? I'm using yosys 613334d, trellis 4e0b215, nextpnr dd7f7a5 (built on Dec. 11), and the most recent LiteX
<somlo>
no matter whether I try to build a Rocket system at 60 MHz or a vexriscv at 75MHz, when it tries to tftp-boot "bios.bin", the tftp server sees the requests and replies to them, but the ecp5 board acts like it never receives any return traffic, and fails out of netboot
<somlo>
_florent_, daveshah: ^^^^
<daveshah>
With whatever Yosys nextpnr and LiteX I have (circa a week or two old) it seems alright
<somlo>
daveshah: do you have a copy of the bitstream you could share -- so I can rule out *physical* hardware and networking?
<somlo>
daveshah: nvm, I grabbed a really old one I had from months ago, and it tftp's just fine
<somlo>
it's gotta be at the intersection of my specific toolchain, litex, and liteeth version
<daveshah>
Sorry, got hit by a power cut which briefly took out the phone masts too
<daveshah>
Will continue looking once power is back
<daveshah>
So as far as I can tell, with latest Yosys and nextpnr, it is fine
<daveshah>
that was with LiteX 3d20442f and liteeth f2b3f7ee
<daveshah>
Seems to work fine with latest LiteX too
<somlo>
if you get a chance to try it on a 5g versa and tell me if ethernet works for you -- because it still won't for me :(
<daveshah>
somlo: works fine here...
<somlo>
ugh... works fine here with my *other* versa5g board... What I don't get then is why that really old bitstream I tried on the "broken" one *did* work...
<somlo>
anyhow, me and my weird hardware heisen-bugs, sorry for all the noise :)
* somlo
needs to add "try another board" into his troubleshooting workflow :)
<daveshah>
Guess it is something marginal around the RGMII link to the phy
<_florent_>
somlo: it could be worth adjusting the delays values of the DELAYF:
