dd-multi.sh: add --keep-files

2019-04-26T13:00:20Z

The first couple steps of the dd-multi.sh script is to: 1. make a sparse copy of the original image 2. loop mount the copy 3. unpack the layers to the loop mount 4. create a vmdk of the copy 5. copy the image and vmdk to the usb drives If many USB drives need to be prepared at once, usually the dd-multi.sh script will need to be called multiple times (due to not enough USB-3 ports being available). However, there is no need for steps 1-4 to run each time. Add a --keep-files argument that will not delete the copy and vmdk files on completion. The --keep-files argument also tells the dd-multi.sh script to look for existing copy and vmdk files. If they are found, they are used. Signed-off-by: John Ogness

Makefile: use literal strings instead of escaping

2019-04-26T10:33:25Z

Although the escaping was correct, it is ugly and bug prone. Use literal strings if static strings (no variables) are involved. Signed-off-by: John Ogness

layer-building/yocto: update scripts for 2.6.1

2019-04-26T08:54:00Z

Use the latest thud stable and also cleanup the scripts a bit so that it is easier to update the version in the future. Signed-off-by: John Ogness

schulung_tools/yocto-own-layer: add u-boot howto

2019-04-25T08:22:55Z

meta-schulung does not include building u-boot. However, building/running u-boot with qemu is quite easy. Add a mini howto with the steps to help the trainer quickly demonstrate u-boot. Signed-off-by: John Ogness

meta-schulung: add app much sooner

2019-04-18T08:02:14Z

Add the application after creating the layer. This allows the participants to see the minimal efforts needed to create their own applications. The layer can be used with any machine (for example, the qemux86 machine that the participants had already been working with). Signed-off-by: John Ogness

dd-multi.sh: inform the trainer how much to dd

2019-04-09T13:53:52Z

The dd step is the longest, so showing the progress is nice. But dd does not show how big the file is. Hard-code the size since we know how big it is. Signed-off-by: John Ogness

dd-multi.sh: use dd features from stretch and 128M blocks

2019-04-09T13:48:18Z

All trainers are now using stretch (or higher), so use the status=progress feature. Also, increase the blocksize to 128M since that amount should be available on the cloning host. Signed-off-by: John Ogness
