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: number of raspberry pi 3 made?

I checked about the bootloader. So, make sure any bootcode bugs are recorded in our issue tracker, and we will eventualy get round to loking at them. Thanks for the check. (I already knew it though.) The issue tracker has many PXE reports already. However, none of them are of "general instability",...

On the topic what a closed bootloader has stopped me from doing I'd like to mention reliable network boot. The current PXE ...

This is interesting, but I am afraid it does not apply to my case. I should have a lot more RAM than 1GB.
You need to provide additional information about your use case for us to understand your overall problem. Why all the RAM?

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...

is it reliable to hot backup a live and working block device
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.

What is the basic problem? Why do you need to reboot so often? It really shouldn't be necessary.

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.

Re: Raspian or what ? ( semi rant)

If you need reliability my Nard project is spot on for you. Tested for long term operation. Excellent for headless mode and has super simple cross-compiling of everything. It makes YOU in control.

Re: Compress SD card for Compute Module lite

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.

Most likely not. Zymbit might be able to raise the bar a bit, but if they advertise a $1000 reward I'm sure their design would be hacked in a few days.

It runs entirely from RAM, so no writes to the SD card.
Another ramdisk distro alternative is my Nard.

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.

This has only to do with the "add-on" in Nard being donationware. As compensation for helping the project with your time you of course acquire access. More info.
