I started form the mangOH sources on github (for legato 16.10) to create my own Legato system.
This should run on my mangOH green board with a WP8548 module.
The build process in my Developer Studio IDE resulted in a \Target_Legato_Release folder with a number of files and subfolders.
It contains a file mangOH_Green.wp85.update which can be installed via the button ‘Build and Install app’.
If I want to ‘Flash firmware from external file’ there are a number of .cwe files that can be chosen:
legato-squashfs.ubi.cwe
legatoz-squashfs.ubi.cwe
legato-yaffs2.cwe
legatoz-yaffs2.cwe
legato.cwe
legatoz.cwe
What is the difference between these .cwe files, and which one do I have to use?
legato.cwe is the symbolic link legato-squashfs.ubi.cwe
legatoz.cwe is the symbolic link legatoz-squashfs.ubi.cwe
“legato-squashfs.ubi.cwe” is the one I normally downloaded to the module.
“legatoz-squashfs.ubi.cwe” is the compressed version.
I cannot find “legato-yaffs2.cwe” in legato 18.4.0. But I believe it is about the rootfs partition.
