Yeah, just hit the same thing:

There are only 'skip'ped commits left to test.
The first bad commit could be any of:
2f9efff
4f23e4e
5760a16
We cannot bisect more!

Those include litex submodule updates. So a lot more in there to test...

Can you confirm that v0.0.4-399-g33b53ba is the last version that works correctly?

[CarlFK]

v0.0.4-399-g33b53ba errors:

[mithro]

So, when is a revision that actually does work?

[CarlFK]

this suggests it works:
(testing it again now...)
https://veyepar.nextdayvideo.com/static/temp/opsis-v0.0.4-487-g5940dcb.png

for sure this is solid - used at quite a few shows:
v0.0.4-340-g3fb4e7c

[stefanor]

I think this was fixed? v0.0.4-721-gc27ca25 seems to work
