Beware the odroid firmware.
Which one you mean? Some specific one from https://wiki.odroid.com/odroid-xu4/soft ... _fw_update ?
There are several versions inside jms578fwupdater.tgz linked there, the v173.01.00.02 is even from 2019.

Re: Rasberry Pi 4 stops working after x number of hours / days

Is the green light (sd card activity) almost constantly on? I have similar experience with Chromium in Buster on Pi4 2GB. I leave it alone with couple of tabs open and no SD activity and enough free memory left and over night I often find it with green LED constantly on like if it is out of memory a...

Re: Update for Rpi Zero W?

As you note, price is kind of a big deal when it comes to a $5, well, anything. Indeed. However the OP asked about Zero W and that one is $9. And the WH variant without quantity limits is even more. So while the $5 Zero is difficult for many reasons related to price, the W/WH price hopefully allows...

Re: Pi 4 with Raspbian Stretch?

Re: Does the foundation produce the Zero under cost?

I don't believe it's made under-cost Maybe it is not made under cost but Zero for $5 or Zero W for $9 is sold under cost. That's why shops can limit how many of them they can sell you. Some shops will sell you one piece ever and refuse second because they are simply losing money on this. Some will ...

Re: default 100 meg swap file

Yes, in general, swapping to SDCard is bad, but it's better than letting the system kill processes to free RAM. This would be true if the default value was not 100MB. Without swap you get killed processes but the system works. With 100MB swap this gets filled almost instantly and you get swapping h...

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 ...
