Schematics "USB Power In" shows incorrect CC1 and CC2 pulldown

[RowanP4069]

The schematics (accessed 2021-06-17) have not been updated for the new USB-C Power In circuit. They still show CC1 and CC2 shorted and pulled down by a single 5K1 resistor (R79).

Schematics will be moved outside of the documentation repo during the reorganisation, see #1911. We may look at this then.

The current schematics will be available in the new docs world, just in a different place. Updating them is a different issue and may or may not happen.

I meant that I don't see the point of having schematics if they're not going to be kept up to date.

We have a very limited amount of engineering time. It's on a list, but the list is very long, and it's not near the top. I'll be looking at this issue, alongside other similar issues to do with ongoing maintenance of the documentation, as part of #1911.

Raspberry Pi's are not open source hardware, and we are unlikely to change that stance.

Can we bump this open again please... the docs site update happened some months ago and this wasn't addressed and now we have no external tracking for when this gets done.

[JamesH65]

There is no schedule for this, nor is there any guarantee it will actually be done.

Sad.

Then what is this:

They published a schematic. They should update it to reflect the state of the production hardware. This can be useful to people developing hardware based on the CM4.

Pretty disappointed by this answer. It's absurd to publish the v1 schematics but not update them later. What are you guys afraid of ?

I'm currently learning about electronics and USB-C. I was about to make the same mistake you did, connecting CC1 and CC2 together, but I've been lucky enough to come across the RPI 4 case. "Great!" I thought. "I'm gonna look at their fixed schematics to see how they fixed that!"
And then I discover that it's not fixed yet after many years, for dumb pretexts.
I've been advocating for Raspberry boards since the first one, but I see that I've been misled. Sad.

As I said up thread. We have a small engineering and documentation team. It's on a list of things that need doing, but the list is very long, and it's not anywhere near the top. Calling us names isn't going to help your case.
