Re: PoE HAT - USB Ports not working - over-current

Does that mean that the Engineering team have managed to reproduce the issue? Or that they have just ruled out basic contact/interference between the hat and some element of the board beneath? There was a suspicion that people may have been not using the provided spacers and pressing the board down...

Re: Official PoE HAT: two of them, running hot

Hello all, I got the new Hat yesterday and two Pi 3B+'s arrived today. Connected them all up, downloaded fresh Raspbian, booted up, ran an update and dist-upgrade. Works fine but I was surprised at how hot the Pi and the Hat are, despite there being no software load and no extra hardware plugged in...

Re: POE Hat - possible boot loader issue

Would somebody who's seeing the problem be able to take a couple of photos of the pi while it's happening? Specifically a side on view from HDMI connector side to see how the HAT sits on the pi would be helpful.

Re: [SOLVED] start an service very early with SYSTEMD

You can configure a pin to act as the power button on a regular PC would, which is how I would approach this. not really, you mess the I2C bus and looks more like tweaking/diy rather than an official setup the pi can handle and keep working properly Was that meant to be a reply to me?

Re: Is this still the procedure with 3 B + .......... ?

No, you shouldn't have to set the OTP bit and that vcgencmd will give you misleading results, since it's a different bit on the 3B+.

You should just be able to flash the latest version of Raspbian onto a USB device and boot off it.

Re: RPI POE hat and 40 pin header access

We put the 'EEPROM' on 0x51 instead of 0x50 and modified the firmware to cope with that. So it is indeed stackable with other HATS. It only uses the ID pins, so any other HAT should be stackable with it without conflicting pin states. Good to see ... and perhaps should have been in the technical sp...

Re: RPI POE hat and 40 pin header access

You can use the extra tall headers on the POE HAT as well, but you'll need to add a 2x2 one for the extra pins as well. That HATs, by definition, are not stackable, and the POE HAT is indeed a HAT. We cheated. We put the 'EEPROM' on 0x51 instead of 0x50 and modified the firmware to cope with that. S...

Re: Seeing errors after update of Bluetooth packages

It doesn't matter, unless somebody reports otherwise. Although it would be nice to update the services such that it starts if serial1 is found rather than waiting for serial1. My systemd knowledge is a bit lacking there at the moment.

I'm not in front of a computer, so can't check. I think it's the same as dist-upgrade, but for 'apt'. Since dist-upgrade was a misnomer which resulted in a lot of confusion.

Re: ETA for Official POE Hat for 3B+

Having a constant slow speed seems like it might be a good option to try. I don't have it here, so I'm going off memory. There may be some mistakes. in /sys/class/hwmon/hwmon0/ you should see a file named 'def_pwm'. That contains the default PWM value that's loaded as soon at the HAT gets power. Wr...
