<LiquidAcid> pokazef, and got that fan working properly? ;)

<pokazef> LiquidAcid: I'm still working on it, but I need to take break for a few days, it's driving me crazy.
<pokazef> LiquidAcid: Believe it or not, right now my U3 refuses to boot when the serial console is disconnected
<pokazef> It looks like a defective power supply, but it somehow works with the old bootloader and kernel...
<LiquidAcid> pokazef, your problem sounds similar, you can double-check by attaching the cable after the device "hangs", if you then find yourself on the u-boot prompt it would a pretty strong indicator that you'r seeing the same issue
<pokazef> LiquidAcid: I'll check that symptom when I resume working on it, thanks for the tip.
<pokazef> LiquidAcid: But as I recall, I wasn't getting any response whatsoever when attaching the serial adapter on the fly.
<LiquidAcid> pokazef, not even an echo?
<LiquidAcid> pokazef, that you won't get any direct output is obvious (if we assume that you're on the uboot prompt)
<pokazef> LiquidAcid: Oops, my bad. It seems I'm on the u-boot prompt.
<pokazef> LiquidAcid: I'll try applying your patch to u-boot and see how that goes.
<pokazef> LiquidAcid: But not today, though. I need to clear my head first.
<pokazef> How can this kind of problem happen with one power supply and not happen with another?
krzk has quit [Quit: Ex-Chat]
<pokazef> It reminds me a little of my Raspberry Pi days, when every USB bug was blamed on a faulty power supply :)
<LiquidAcid> pokazef, iirc the issue occured randomly -- since it disappears as soon as ethernet or hdmi is connected i would assume that it's a grounding issue with the pmic

<pokazef> LiquidAcid: Low-level power bugs are scary...
<pokazef> And by the way, is it possible to do any permanent damage when misconfiguring power management / voltage regulation stuff?
<LiquidAcid> pokazef, i'm not sure if this is really a power issue in the sense of the hdmi-current-feedback one
<LiquidAcid> pokazef, of course, so always check for any additional zeros when setting regulator voltages ;)
<pokazef> LiquidAcid: I'm not used to that kind of responsability when compiling a kernel...
<pokazef> I wish this kind of stuff stayed in hardware
<LiquidAcid> pokazef, just double-check everything if you're working in that area
<LiquidAcid> pokazef, what do you want to do anyway? add these 2ghz frequencies?
<pokazef> LiquidAcid: I see no reason why I should be, but thanks for the head-up anyway
prahal has quit [Quit: prahal]
<pokazef> LiquidAcid: Nope, I have no reason to touch any of it. It's just something I had been wondering.
prahal has joined #linux-exynos
<LiquidAcid> pokazef, then i wouldn't worry too much
<pokazef> LiquidAcid: OK, thanks

<pokazef> LiquidAcid: I just applied your patch to u-boot v2016.03 and I still get the same behavior.
<pokazef> Luckily, I can just use the other power supply, so it's not a big problem for now
<LiquidAcid> pokazef, hmm strange, no idea then
<pokazef> It's ok, thanks for the help
<pokazef> LiquidAcid: is there some backlog in the u-boot console that I could check, BTW?
<LiquidAcid> pokazef, you mean like some scrollback buffer?
<pokazef> yep
<LiquidAcid> hmm, not that i know of
<pokazef> Oh well
