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...

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...

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...

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.

so I don't use the WiFi! Indeed. With 3B+ I use as a desktop I moved to wired ethernet too as I have it near. Also I play streamed games over Steam Link occasionally and the wireless in Pi3 has some performance issues documented here - it works fine but slows down every few (5, 10?) minutes killing...

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 ...

When you can have 64bit kernel with raspbian? You already missed it. https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=232684 https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=232417 https://github.com/sakaki-/raspbian-nspawn-64 It is 64bit kernel (as you wanted) and 32bit raspbian as ma...

you may try to switch to old non-MESA closed source GPU drivers via raspi-config and see if it helps?

If just looking at getting something better at the same price then the 1GB makes sense, but I would have thought an extra 1GB for $10 or an extra 3GB for $20 would lead people to choosing 4GB. Plus getting the most one can is insurance against finding one needs more in the future than initially tho...

It is not sold out, there is still 2GB version here https://thepihut.com/products/raspberry-pi-4-model-b If you want specific RAM size only then please rename topic title. BTW, 2GB was my preferrred model so yesterday I ordered that one immediatelly, looks like I am a minority, everyone wants 1 or 4...

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...

fanoush

Is there still VC4 style (dual core) VPU? Does the ARM boot first or still the VPU?

Anyway, what HawaiianPi said worked for me with multiple Zeros. I have same experience - with same monitor other Pi work but Zero does not show the picture unless increasing config_hdmi_boost. Also since it is miniHDMI often the additional mini to full hdmi adapter attached to same cable is enough t...

you can run 32bit raspbian with 64bit debian inside container, this is relatively painless with best of both worlds, see viewtopic.php?t=232417

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...

Also, I looked it up and google says that lithium batteries cannot charge while discharging. Am I not understanding something that would allow this to happen? The idea is that to charge and also run it at the same time you need to provide more power than what your robot needs. So you don't charge a...

It wouldn't hurt to use dist-upgrade, so the documentation isn't wrong as such, but it is rare that it is needed. So you are only trying to save typing few letters (and so if 'dist-upgrade' would be renamed to 'u' you would start using it immediatelly) or do you believe the 'upgrade' is somehow saf...

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...

way, after the reboot I wasn't able to connect to the RPi via VNC or Terminal. I attached USB keyboard and mouse and the monitor and there was no action at all... even the screen was blank. So, fearing the worst (corrupted uSD card) I pulled the power plug, waited a minute and reapplied power. All ...

The only problem i have is that i have to manually solder wires to the usb to sata adapter or cut the usb wires and power like that. And still share a common ground. Western Digital sold their PiDrive hard drives with splitter cable. The power went from power supply first to HDD then to pi, see e.g...

What can I do to make the pi boot faster on raspbian stretch lite? You can use raspbian stretch lite card to use the software but you can start only your custom script without anything else running. There is linux kernel parameter init=/path/to/your/executable so you can just run your code directly...

That adds additional complexity and power requirements. ..... Perhaps a B+? That adds additional complexity and power requirements. ;-) Like Ethernet. Zero with usb hub might still be cheaper and lower power than b+ Apart from generic hub there are hubs for Zero, one is http://www.uugear.com/produc...

I found Zerotier https://www.zerotier.com/ to be quite painless. I use it occasionally to stream games to Steam Link on pi3B+ from Azure VM. You just install debian arm client on the pi and rest is configured via web on ZeroTier site - setting up networks, assigning IPs.

The dual band 5GHz wifi chip from 3B+ would be nice on Zero W eventually.

That is cool. I never imagined I would ever want to buy a smart watch or any kind of fitness tracker. But you have made this irresistable. DS-D6 is curently cheapest but there are a bit more choices now. Few days ago Banggood had a deal with Lenovo HX03W for $9.99 (still B/W OLED but wider), this o...
