this is really ridiculous. The foundation messed up big time and should make an announcement when this is fixed with a new board revision.W. H. Heydt wrote: ↑Sat Aug 17, 2019 5:35 amThe simplest power cable solution (if you don't want to use the RPF PSU), is to use an inexpensive cable. It's the fancy ones with built in chips that cause problems. I.e. Don't try to run your $35 Pi from your $60 Apple PSU.
As for when such a change happens... Nobody outside of the RPT knows, and they aren't talking. I suspect they're waiting to see if any other changes are needed or warranted. It is also moderately likely that there won't be any actual announcement when the changeover takes place. So, if you can make use of the Pi4Bs now, go ahead and get them and don't let the future put you in fear of the present.
This is really tedious. People keep posting about being irate that the issue exists, not that they have found that their Pi 4 doesn't work because of this issue.
Yep really messed up not allowing a $60 PS to power a $35 computer.this is really ridiculous. The foundation messed up big time and should make an announcement when this is fixed with a new board revision.
Nonsense. This is a minor issue that only affects a few people who for some reason don't want to pay a few pound dollars for the proper power supply. Really almost a non-issue.
I think the arrangement of your image could be pushed into the middle of the text.
Strictly as an onlooker as I am not affiliated with the organization, there is some room for speculating a time-frame. Helpfully, eLinux.org has a time-frame with some dates towards the bottom. According to this information the initial 10K batch of revision 1 boards was announced on February 29th, while full production was announced in April. The revision 2 board was announced September 5th (thanks to Archive.org, since the link to http://www.raspberrypi.org/archives/1925 no longer works).glenk wrote: ↑Sat Aug 17, 2019 1:40 amDoes anyone have any insight into what the timeframe for this might be? If we are only talking weeks, which if I understand they are basically selling all of the devices from the factory as they are made, might be possible as there isn't much stock being held on hand, or are we likely talking many months?
The Raspberry PI 4 incorrectly implemented part of the USB-C specification. That is the Raspberry PI Foundation's fault. For all the railing against smarter power supplies, making it less likely a dumb one will burn down your place of residence has distinct value.
who did wrong here is obvious.. there's no way to blame someone else than RPT.. not even with but nobody will do blablabla.Gavinmc42 wrote: ↑Wed Oct 23, 2019 11:45 amYep really messed up not allowing a $60 PS to power a $35 computer.this is really ridiculous.

Their official PS works with Pi's, did they mess up by not making it run Apples?
Surely this is all Apple's fault?
Just think of it as a feature, no one is going to pinch your Apple PS to run a Pi4.
I have a $15 AUD PS that runs two 4's and two Zero's.
they have a proper power supply which follows the USB-C specification. There's no reason to blame apple nor apple PSU users for RPT did a mistake when designing their power circuit. I was wrong, it was acknowledged that they did wrong and for sure the next board revision (not major update like a 4b+ or whatever follows) should address it. Mistakes happen, it's not the first one and it wont be the last one. It's IMO not a terrible one but never the less there's no reason to blame the people using such a PSU nor the company which provides such a PSU. It wasn't their fault that the implementation doesn't follow USB-C specs.rpdom wrote:Nonsense.

Yup, and this is the problem with announcing any date. People will assume that purchases after that date will be the new board revision, and then more chaos and complaining happens as the remaining old stock ships. Or they will only want the new board and dealers will have trouble selling off their older inventory (I'm sure the click-bait news media will play a big role in the latter problem).
That's been pretty much my assumption about how it will work. I might also speculate that there might be other--minor--revisions while the PCB layout is being reworked. The only--and again, minor--item of interest would be if the board revision will be marked on the board so that one can easily tell at a glance which PCB version one is dealing with. (Mind you, this won't affect me either way. Not owning any Apple or other "smart" USB-C devices, I'm running Pi4Bs exclusively with RPF USB-C PSUs.)jamesh wrote: ↑Thu Oct 24, 2019 5:00 pmNot sure what difference knowing when the change will percolate through will make. People who want a fixed board will need to wait until it's out, whether they know the date or not. From our point of view, demand is still outstripping supply, so sales are not affected. My presumption is that we won't announce it but just let the manufacturing change over as supply lines adjust. There is bound to be a period when the old and fixed device are both on sale. But I am not privy to the plans so take that with a pinch of salt.
I think you'd just need to connect a single resistor to ground in the cable/adapter (which would be even simpler).
That's really the issue.Maybe there just isn't enough demand for it.
Which, in a roundabout way, validates my original point.
Not that simple, reading near the start of the thread it seems you need to cut a trace which one person achieved by lifting the physical pin of the connector off the board.HawaiianPi wrote: ↑Thu Oct 24, 2019 6:07 pmI think you'd just need to connect a single resistor to ground in the cable/adapter (which would be even simpler).
Isn't that equivalent to leaving the pin in the plug disconnected? Then put a resistor from the (disconnected) wire to ground in the plug.
