13:48 <maz> well, it looks like my brand-new RPi5 isn't happy and turns itself off as soon as it sees power. I guess that's one way of saving energy.

13:50 <Xogium> maz: did you get their non standard psu ?

13:51 <Xogium> yes because pi 5 wants 5v 5a. They require a non standard psu to manage this though, because, because well, rpi foundation just didn't want to add a stepdown converter on the board

13:52 <Xogium> so instead of doing the proper thing and requiring 12v for giving out that 5a and getting it down to 5v, they decided, hey lets make a non standard usb-c psu that will deliver 5v 5a

13:58 <Xogium> honestly I already was no huge fan of the rpi before the rpi 5, but this rpi 5 business requiring a non standard psu and meaning you can't use any random usb-c psu definitely put me off ever getting a rpi even to toy with it

14:01 <sven> huh, did they mess up so badly that a normal type c psu won't even work with limited performance?

14:02 <Xogium> sven: I am not sure. But this is the first thing I thought of when maz said their rpi 5 wouldn't power on

14:02 <Xogium> iirc regular psu have max 3a @ 5v

14:04 <sven> would be disappointing if that's not enough for average load :/

14:04 <Xogium> honestly some kind of mess up seems almost unavoidable to me given the rpi is cheap in the power management department

14:04 <Xogium> for instance rpi 4 couldn't use any random usb-c psu either, in fact it would especially dislike the psu that did the proper thing with usb power delivery

14:04 <sven> oh yeah, didn't they also mess up the CC line resistors in some previous board which then failed if the charger actually followed the USB PD spec?

14:05 <Xogium> yep

14:05 <Xogium> exactly that

14:07 <Xogium> I'm still surprised that rpi is still getting so much traction given the increasingly weird things they've been up to

14:07 <Xogium> rpi 5 took out the hw h264 decoding

14:07 <sven> i still like the rp2040 / pico boards

14:08 <Xogium> yeah, those rae not too bad

14:08 <Xogium> *are

14:10 <Xogium> but personally, I'd sooner buy an orange pi 5+ than a rpi. Way more attractive

15:03 <maz> Xogium: yeah, the custom, nih. not that it change anything as it doesn't work with *any* other PSU.

15:04 <Xogium> ah

15:04 <Xogium> that was my first idea

15:05 <Xogium> maybe you got a defective rpi :/

15:09 <maz> and for the record, the spec doesn't say it *needs* 5A. it says that if the PSU isn't capable of 5V@5A, the amount of current on the USB ports is reduced. not quite the same thing.

15:10 <Xogium> ah, so they did the right thing for that, after all. Good

15:10 <Xogium> still a dumb idea to have not put a stepdown converter, but
