MM keeps freezing

Thanks. I have never seen the lightning bolt icon on any of the mirrors displays. I use the USB output of the display controller. Power comes from this https://www.amazon.de/gp/product/B01AA83VHA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and is attached to this display controller: https://www.amazon.de/gp/product/B0756ZBB2G/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

@requiemmg IIRC, the lightning bolt went away with Raspbian Buster.
-
@requiemmg Did I understand correctly that the display controller powers the Pi via its USB port? If so, I very strongly believe that this might be the source for the problem for two reasons:
- The USB port does not provide enough power for the Pi
- If the display controller goes in standby, then probably the power provided via its USB port might also be reduced.
I would always recommend to connect the Pi directly to a dedicated power supply, which can supply min. 2.5A.
-
@Fozi Oooh, good call. Strong power is good power. Part of the reason I upgraded to Pi4’s for most everything, honestly. Got tired of the weak power supplies on the old USB spec, so…
-
Okay, I’ll try this. Did also not know that the bolt signal is no longer available with current Raspbian.
Oh, the controller does not enter standby, I have it running 24/7.
Ordered a power supply with 3A to be sure. I’ll report back. -
FYI. the bolt is still active, fresh copy of the OS downloaded from their website, on RPI3b+. whipped it together so to test for mirror frame placement.
-
@BKeyport - Good to know, thanks.
-
So, both mirrors are now running on an external 3A power supply.
Unfortunately, the still keep freezing. I fear that I have to setup from scratch, step by step, to see what is causing this. :-( -
Yeah, that would be a good idea, who knows what got screwed up on the old SD cards with the freezing.
-
Installed to both fresh SD cards as well as USB stick before, fresh setup! Only thing that was copied over was the config.js and main.css
