I haven't tested it with Pi 4, but likely it will work to some extent. Not 100% optimized of course, but better than nothing. Feel free to help out with improving it. :)

Have a look at my project Nard SDK which is exactly what you're looking for. A RAM only embedded Linux distro.

Re: Raspberry Pi 3 in Kiosk mode

There are many kiosk mode options for the Pi. But I (of course) promote the one developed by me. :) Nard has a kiosk demo which might be what you seek. Just write the SD card and edit the URL as described here:

Would it be possible for bootcode.bin to load a second-stage ARM-based PXE boot loader that could then be open source?
Possibly. But it's a lot of job for a workaround. Also remember one need a Pi specific USB driver.

Re: Is it reliable to backup Raspi from remote?

So, in other words, there's no way to backup a Raspberry embedded in a big project without stopping everything In embedded systems one usually don't need full system backups. What you need to copy is only the unique data the embedded system collects/generates. In the event of a SD card corruption o...

Of course it's not! And the official SD Card Copier which does file-by-file copy is not safe either! It may or it may not work. You will never know for sure until actually running your backup.

There is no need for two devices. Using only the right Pi is sufficient, and let windows connect with IP to it. Possibly with the help of some "virtual" COM port driver.

Re: Adding LAN 7850 driver to older kernel

I'm also using kernel 4.4 and has just gotten it to run on Pi 3B+. It's likely the lan78xx driver you want, because that's the one needed for 3B+ wired Ethernet. Have a look in my Git repo where you can find backport patches.

You might want to look at my project Nard which instead works by creating a master image all in your PC. That image is about 40 MB and can later be written to the CM.

Re: Possibility to boot via PXE and load filesystem into ram?

This is an old thread, but I can answer.

The answer is no. PXE support is way to buggy in the bootloader. One can use it on a lab bench. But for any serious mass deployment it's way to unreliable.
