A simple script can do kernel7.img backup, swap and then reboot to ultibo program. Then a simple procedure in Ultibo program can swap them again and reboot, returning to Linux
Of course in case of bug/fail/hang of the Ultibo program one will have to put the sd out of the RPi and manually swap the files.

I noticed recently that config.txt can tell the bootloader.bin which kernel to run.
I was using piCore and the kernel file name was long and had the revision in it.
So maybe we could make a grub loader?
How does NOOBS do it?

That is workable but just barely. Should be able to set up a minimal fs to upload over a minimal wifi or usb and do a project template and bypass the need to reload a full OS. Even that is rather 'fragile' sounding.

Perhaps an FTDI solution is a more practical route, like the EzSBC uC. This sets the FTDI chip up to show as amounted hard drive on the host machine. http://www.ezsbc.com/index.php/featured-products-list-home-page/ezsbc2.html#.WBBkaa32bRY

Certainly this can be accomplished with an FT2232h. Reading/loading the sdcard from the host is strait forward. If we have that then it's simply a matter of physically tapping the card to the card reader.

There isn't much chance that Ultibo will be taken over by a corporate raider anytime soon, and there certainly isn't any offer on the table.

The article was more of an observation about the perception of value and especially the way we judge the value of open source projects. Lately we've been working on writing up info to send to potential sponsors and as part of that we've been doing a lot of thinking about exactly what we are trying to achieve with Ultibo.

In the beginning just getting the idea to work was enough of a goal but we've gone well past that point so it's appropriate to think about what the larger goal might be over the next few years, it seems pretty safe to say we aren't trying to launch the next big tech startup. In actual fact creating a platform that makes bare metal accessible to anyone (as Tony pointed out) is more like the real goal of the project, it's been great to hear your thoughts on this topic and we appreciate all the different perspectives.

Cheers,

Garry.

PS. Congratulations to pik33 on the PhD, now we know who to send the really hard questions to :)

I need the full OS to run ultibo environment/Lazarus - to develop and run the program on the same RPi and not use PC/Windows. Develop on the Pi - run on the same Pi
