Re: Zero W not booting or ACT LED

My advice, FWIW, is patience, they will be back in stock st some point. In the meantime, stay safe.
Any idea how the chip casing (which chip?) inductor was damaged?

Re: Rpi 3B+: how cold can it still opperate?

This summer I'm planning to install a solar powered Pi as a game camera at my camp in Eustis. Next winter should be interesting.
Love it there too.

Re: Rpi 3B+: how cold can it still opperate?

I live in central Maine and have had 6 Pis deployed outside 365 (sometimes 366) days a year, for approx 3 winter seasons. All but one are Pi0Ws, in small Styrofoam boxes with a rectangular hole cut in the bottom, covered by a screen to keep out little heat seeking critters. The other Pi is a 4B4G th...

If the power (green) LED blinks once and goes off, it's an indication of a power issue.
What are you using for a power supply?

Re: Raspberry Pi for saving marriage.

I have found through trial and error that prevention of the spawning of child process(es) may lead to overall system stability.
This requires at least a patch (and subsequent re-patching), or in some cases removing the ability to spawn entirely.

Forgot to mention, I tried to revert to afbea38 via

and no joy.

The switch has a prevision for external power, tried that, still no joy.
I'll get another switch with a different chipset, and see how that goes.

Re: Issue with IOGEAR USB switch after latest update (1/24/2020)

Rosioara,
Thank you for your response.
In my case, if I connect the mouse and keyboard directly to the Pi4, all is good (with no changes to config.txt),
Only when I use the USB switch.
I tried over_voltage=1, but no joy.
FYI, I received the Pi4 on 1/20/2020.

Comparing syslogs from today (or last night) vs pre-update.
The mtp_probe messages are new, not sure if they are germane, but they are new.
Possibly a recent update to the udev rules?

If the latter, it can be done by disabling in /boot/config.txt.
