Go to their userpage to see the photo they posted of another board but no confirmation this is a v1.2. It must have gotten caught in the spam trap.Cob wrote: Brand-new Reddit account and no photos after 5 hours?
Yes. It is probably a troll post but there is a chance they're telling the truth. A photo of the revised Pi 3B with the heatspreader topped SoC from the 3B+ appeared early as well.
Unlikely... You can update the firmware on a Pi4b without needing a hardware change.
It's getting closer every day...
The term "firmware" is used quite loosely for Pi. There is the ROM bootloader firmware in the SoC which cannot be changed without a silicon respin, the firmware in the Boot Eprom, firmware for the GPU which loads from SD Card at boot, firmware for the WiFi/BT module, for the USB host chip, possibly the LAN chip, TV Hat, PoE HAT and other smart peripheral components.
I'm guessing yes. The two issues were posted by established users that were registered years ago and the LibreELEC kernel log is from September. If it was a troll post then I'd expect one of the Pi engineers to have said it was a fake by now.
Yeah. The original Pi 4 was v1.1 at release but it wasn't marked on the silkscreen. Something has changed to bump it to v1.2 but it wasn't the PCB artwork. If the photo is accurate then it doesn't have the USB-C CC resistor fix yet.
I'd expect the silkscreen to be updated like previous Pi boards if the PCB was altered. There isn't any clean way of doing the USB-C CC resistor fix without altering the board as the connection between CC1 and CC2 is under the socket itself. Besides, the complaints would get even louder if you couldn't identify a fixed board without staring at SMD components.GaryH1 wrote: ↑Wed Nov 13, 2019 8:32 pmDon't forget that there are some components on the underside of the PCB, so the additional resistor fix needed for the USB-C issue may be there. We haven't seen any pictures yet of the underside of the supposed rev 1.2 version. As it's an engineering change I would expect the revision number to be bumped.
Except that, unlike previous Pi boards, the Pi 4B has no revision number on the silkscreen that would need updating.
Got any verifiable links to that information (not criticizing, just curious)?
It is odd it doesn't say v1.1 on the silkscreen but I expect them to add it or it will be a nightmare trying to determine if you've got a fixed board or not.
The new 3B with heatspreader topped BCM2837B0 still says v1.2 with a 2015 date as the PCB wasn't changed. If the v1.2 board didn't have any PCB artwork changes then no silkscreen changes isn't that strange.
I looked at the board under an inspection microscope. There is no visible trace connecting the two pins together on the top. R1 and R79 are on the bottom with a via in the middle but there is no sign of the CC pin connection. There are some x-rays of the Pi 4 and one of them is a close up of the USB-C connector area. You can just about see a trace going between CC1 and CC2 underneath the socket.
Just noticed the 3B+ doesn't have a revision # either.
