Re: Pi 3 A +. What is it for?

Pretty much any experienced software engineer can tell stories of days, weeks, spent debugging a problem only to find at the end of it that the fix is a one line change. In the last four weeks I have been debugging an open source gcc based compiler that has been producing one error under Buster wit...

Re: Auto locking threads

Lock threads after 3-6 months of inactivity sounds sensible to me. New threads can easily be started if the issue reappears. Better than having people replying to out of date information. I fully agree with this. But it would be nice if moderators would be able to unlock threads on request for the ...

I'm gonna try the above with the latest Buster image, and will try without HDMI (skip touching the config.txt). Will report back
It would make sense to (physically) remove the pisound while testing.

Re: Raspberry Pi 4b - sudo reboot now - need to unplug power > 10seconds to recover

If I simply pull the plug, wait 2 seconds, and plug back in - it boots fine. So it seems like some bad state is being set by sudo reboot now . ( dont worry, I have a RO filesystem, so it's safe to pull the plug ). Background: I'm creating an embedded consumer device, meant to be turned off and on v...

It's a network traffic generator, and I again get packet loss (about 2-5 % measured over several hours). This is with both raspberries using their official power supplies, not external things attached, just the ethernet and power cables. If I power down the pi 3B, the packet losses disappear (I gen...

Re: Packet loss from raspberry 4 ethernet port

Note that I did get the packet loss from pi4 also when pi3 is connected through wlan0 and pi4 with eth0, but not when pi4 is connected with wlan0 and pi3 with eth0. Also when I swapped the sd cards I still get all the packet loss on pi4. I am not surprised: https://www.raspberrypi.org/magpi/raspber...

Re: Keyboard setup in Raspbian Lite

Most likely "Generic 104-key (PC)" + "English (US)" will solve your problem.
I can not test because I do not have that keyboard available to me.
