I imagine having multiple images is used far more often by developers of barebox than developers of a device that uses barebox.

It uses barebox-flash-image if it exists and then falls back to barebox.bin. The latter will still exist in a multi-image build, but is not the correct file! My first thought was to add an option to buildroot for the name of the flash image file. But barebox is the one choosing this name and it knows what it is. So why should I have to manually copy this data out of barebox and into buildroot and keep to up to date when it chages? Barebox knows the value, have it tell buildroot what it is. And there is already the barebox-flash-image symlink system that does just this. This way buildroot (and any other buildsystem or flash or test script that uses a barebox image) gets told what file to use straight from the authoritative source: the barebox build system that made the file. So, that's why I did it this way. And it's not like I'm adding a new feature for this, just making an existing one work in more cases that it did before. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
