Re: Just received my RPi4b/4GB - no HDMI output!!!

My Pi4 finally arrived yesterday and I have same/similar issue with Motorola Atrix lapdock - the only device I currently have with micro hdmi input. So far tried hdmi_force_hotplug=1 hdmi_drive=2 config_hdmi_boost=11 but still blank screen with Pi4 after boot. This same microHDMI extension cable wit...

Re: (again) Raspberry Pi sleep/standby modes software support

I counted the number of SW engineers we have to support the Pi, 8 full time, 2 contractors. To do FKMS, Kernel support, Chromium optimisations, video drivers, camera and other peripheral support, Raspbian development, bug fixes and all the associated background tasks that go with all those. Now tak...

Re: RaspberryPi 4: heatsink or fan

An aluminium case will be of no use unless it is thermally linked to the SOC Which is the case with 3B+ as understand it (unlike 3B) and possibly also Pi4 (sea also this and linked blogs). They explained it somewhere that the SOC is upside down in 3B+ and heat goes into board ground plane, metal co...

Re: Triple display with Raspberry Pi 4

There is also DPI on GPIO pins so that makes it four now :-)
On older Pis I think all three (HDMI,DSI,DPI) worked at the same time in some way.

And there are also those cheap Fresco Logic (FL2000) USB3.0 video cards (popular for SDR) that may work now with Pi4 too.

Re: RaspberryPi 4: heatsink or fan

With no case , I am not convinced the Pi4 needs any extra cooling at all (in the UK at least). Even better is to get aluminum case - it is both big heatsink and case. Especially with the 3B+ model the heat goes to the board itself so it is nicely transferred to the case (unlike with older 3B model ...

Re: Raspberry Pi 4 Thread - general discussion

The VC4 VPU is still there (and boots first). Bootcode.bin has moved to an on-board EEPROM so when we release Ethernet/USB mass-storage bootmodes, it'll be a bootloader upgrade and not a bootrom (new chip) upgrade. I see thanks. So I guess VPU still sets up the memory at startup then. How did you s...

Re: hci0 fails to initialise while scanning for bluetooth-LE in 3b+

I am not sure if I understood correctly what I've read previously but I think some of those libraries takeover the hci interface so the safest is to stop system bluetooth service via something like '/etc/init/d/bluetooth stop' before using it. On the other hand if your library is written on top of b...

It wouldn't hurt to use dist-upgrade, so the documentation isn't wrong as such, but it is rare that it is needed.

Re: Is reboot safe?

This sort of situation rarely occurs, typically when upgrading from one release to another (jessie to stretch, or stretch to buster), but as the general Raspbian way seems to be "start again with a new download", you'll almost never hit this scenario. While it occurs rarely it depends only on packa...
