<gruetzkopf> most likely mechanical damage
<whitequark> pic?
<whitequark> seems very fixable
<gruetzkopf> i crunched a few caps, apparently. C76 is missing a pad, looking if that's crucial
<gruetzkopf> (this is one of atties C1)
<d1b2> <Attie> 😦
<whitequark> C76 isn't crucial
<whitequark> a PLL cap
<whitequark> almost nothing uses PLLs so
<d1b2> <Attie> i meant to mention I got one of mine all tangled up the other day - had to take some steps with glasgow factory --force... not entirely sure why (and didn't take good notes, sorry)
<gruetzkopf> yeah, no trace flowing through that pad, also killed a few decoupling caps on the Port A level shifters, but thats not likely to be an issue here
<gruetzkopf> hmm. i believe i should have a shady i2c tracer around
<whitequark> can you do -vvv first
<whitequark> nvm, won't help much
<gruetzkopf> you'd be looking for anthing past the bitstream upload?
<whitequark> REQ_PULL is opaque on the USB side
<whitequark> and that fails
<whitequark> actually, wait
<whitequark> there's two REQ_PULL
<whitequark> so you'll see which port it's failing
<gruetzkopf> is there 2 REQ_PULL if i only specify a single port?
<whitequark> no, one
anuejn has quit [*.net *.split]
kmehall has quit [*.net *.split]
<gruetzkopf> okay, looks like both fail
<whitequark> hmmm
<whitequark> is there Vio?

kmehall has joined #glasgow
<gruetzkopf> aah!
<gruetzkopf> no, there is not (even though there should be according to the LEDs)
<whitequark> the LED is connected to the EN pin
<whitequark> so it could be a fault before or after the regulator
