This is basically correct - one of the main purposes of the ELDK is to
allow a very quick start without the need to set up a specific MACHINE
configuration and to build everything (root file system and SDK) from
scratch. Instead, we provide be-built binaries for generic configu-
rations while still maintaining the capability to create board
specific configurations.

Yes, correct. Like all the other root file system images, these are
ready-to-use, working examples that can either be used for general
prototyping tasks, or as a starting point for project specific setups.

During development, the workflow is the very same as you've been using
all the time before yocto: you use the tools of the respective SDK
image to build U-Boot and Linux. The source trees used for the ELDK
distribution get installed as part of the SDK images; in the Xenomai
case (installation with "-s xenomai-qte" option) you will find the
following subdirectories under
/opt/eldk-5.4/<arch>/sysroots/<arch>-linux-gnueabi/usr/src:
kernel-ipipe - I-Pipe patched kernel source tree
xenomai - Xenomai source tree
Best regards,
