Re: Raspberry Pi 4B 2GB Price Drop - NOW $35

A 8GB model @ $55 will be nice, when it makes sense to make one. Right now it's too pricy it seems. And so it's not made, anything else would be silly. There's naturally always an usecase for more RAM, that has nothing to do with something being badly written, of course. Bigger datasets to crunch, ...

Re: Does the Raspberry Pi 4 throttle at 60 C or 70 C? (also question about fan PWM speed)

For some background (some of the specific numbers may now be out of date, as I have been waiting for the final DVFS software changes to be shown to work all over) https://www.raspberrypi.org/documentation/hardware/raspberrypi/frequency-management.md Basically, throttling won't start until 80, and wi...

Re: Raspberry Pi 4B 2GB Price Drop - NOW $35

Great news and I am assuming retailers were warned or they will be sitting there with "$45" 2GB boards they have to sell at $35. A major loss in profit unless they were buying the boards at $35 and adding $10 mark-up. Of course they were told, we are not idiots. They've been running down stock for ...

Re: Advice for upgrades

RPI 4B has the TRUE USB 3.0 speeds and fixed the USB bandwidth bottleneck (ethernet and USB are not shared anymore). But power hungry and needs Fan and or heatsink (or just use a FLIR casing) because of the increased clock speed (you can do some underclocking, disable bluetooth and wifi if you will...

Question, does this work on all operating systems for the Pi?
We don't guarantee any level of overclocking on our own distro, and certainly never ever test other people O/S's so really cannot guarantee whether overclocking will work on them.

Re: What is the maximum monitors supported by Raspberry Pi?

DisplayLink style USB display adapters may work, although if they use the Pi onboard 3D block for composition then your overall desktop is limited to 7680x7680 on Pi4 (2048x2048 on Pi3). Yes, i read about that too. But what i really wanted to know was, using every possible resource be it: HDMI and/...

How about $10, 12, 14? That would be better. I mean, RPI would go bust, but must be better, surely?

Or some other random sequence of numbers?

Are you overclocking? Shouldn't need overvoltage unless you are doing that, but maybe it helps in some power supply cases?

Hi,

can you either send a photo of the QR code, or decode it and forward the number. We might want these back here for testing, will get back to you on that one.

Depending on the model of Pi 500mA is much too small.

Re: What is the maximum monitors supported by Raspberry Pi?

For use as a desktop, then 2 is the maximum. So 2 HDMI on the Pi4, or 1 HDMI, one DSI/DPI, or on earlier models, 1 HDMI and one DSI/DPI. @Jamesh, Will this number of maximum screens, as a desktop increase in the future for the Pi4 ? Also is increasing the number of screens, bottlenecked by software...

Have you got any sort of overscan setting turned on, although I think that overscan should be ignored on the LCD panel. (which is 800x480)

That too unlucky to be possible and could indicate a problem elsewhere. The failure rate is very very low, and to get 2 out of 6 not working would be extremely unusual.

Re: RPi Zero W only running at 700MHz

That config.txt entry is a hangover from the very first Pi, where 800 WAS an overclock! Regard it as an example only. Since each model has a different overclocking capability, there isn't a single figure we can put in there. Default max ARM freq for the Zero is 1000 (used when the CPU is under load)...

Hi, Booting from a PNY SSD..... I may have been in hibernation for the last 6 months so sorry if I missed this and revived this old thread, but are you saying you booted a Pi4 from USB? I thought that feature wasn't available yet? It's not. They would need to be using an SD card for initial boot.

The standard debugger is gbd, and that does all those things.

You don't need to be bare metal - you can practice all that stuff under Linux and it's MUCH easier.
