Re: Running Zoom video conferencing client on the Pi

I managed to repeat this successfully on a Pi3B+ as well. The video still freezes if you move to another window, and the video has a little more latency, maybe 1.5 sec. On the whole it is less responsive than the Pi4 as you might expect. I did recover the video from a frozen state by leaving and rej...

I tried gpu_mem=256, but it made no difference. It still froze after viewing the participants window, even without an active connection.

Re: RP4 Install Raspian, Then No Video

If you get the 4 raspberries (and often some scrolling boot text) followed by a blank screen, then a commona cause is often that the new vc4_(f)kms drivers are not working well with your HDMI monitor. This is often due to different parsing of the EDID data from your monitor, or the use of a default ...

Re: RPI4 NOOBS won't display after switching to 4k60p

Try adding a config.txt file to your NOOBS partition and force the display mode using hdmi_group and hdmi_mode etc.

Hi Konsta, I've just installed your LineageOS16.0 for the Pi4 (using PINN of course) and successfully installed gapps so that I can install zoom video conferencing from the play store. Mostly it works quite well (see https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=254367&start=25) but if the...

Re: Microsd slot replacement

Is it just the cover that flipped off?
That happened to one of mine, but I managed to solder it back on again. It is just tacked on with 4 blobs of solder: 2 on either side of the slot and 2 on the opposite edge near the contacts. You may still see their remains through a magnifying glass.

Re: RPi4 with MicroSD Extender Boot Failure

As I stated above, Pi4 uses a faster SD card access method that operates at a lower voltage. NOOBS prevents that mode from being used using the quirks option because it prevented rebooting into a different partition. I suspect that is the reason that NOOBS works and other OSes don't. It would be nic...

Win32 DISK imager is used to backup the entire card, so I would normally pick the first partition (RECOVERY).

I believe the Pi4B uses a lower voltage mode to get the higher speeds on SD cards. Just a thought, but you could try adding 'sdhci.debug_quirks2=4' to cmdline.txt in the boot partition of Raspbian. (You should see that this option is already added to recovery.cmdline of the NOOBS partition.) As you ...
