It is recommended to run +elbe from nereus.lab.linutronix.de because toolchain and eclipse software +are readily available via http mirror. -ELBE generates just the first partition. However the -system is configured that there is a second partition -mounted by label 'home' on '/home'. This was made to -reduce the time needed to 'dd' the image to the disks. +elbe generates all data on 1 partition (16GB in size). This image is fully +functional and has enough space for most trainings. -E.g. i added the following content for the yocto training: ----- - % ls home-overlay/devel/yocto/ - downloads pres_lx-trainer-vm.pdf pres_yocto-basic.pdf - meta-mini pres_yocto-advanced.pdf pres_yocto-intro.pdf ----- +The "dd-multi.sh" script will copy the generated training image in parallel +to multiple devices.
