Setup environment
Get sources and build default images: Instructions
setup.py
- clones all projects
- rerun to update all repositories - then rebuild with bitbake
- creates a working copy of projects-default.json - projects.json
check_versions.py
- compares software versions on the 10393 vs current sources
~$ ./check_versions.py root@192.168.0.9
Flash vs micro SD
- micro SD cards work best for development
- replaceable
- changes get written to the card, no extra sync required
- flash works best for a production system:
- non-replaceable
- limited write cycles
- because of overlayfs changes need an extra sync (overlay_sync) and a proper reboot to get written to the flash.

Change repository address, branch, hash
- change uri: edit elphel393/projects.json
- change hash: edit elphel393/projects.json:
"elphel-apps-camogm":[ "https://git.elphel.com/Elphel/elphel-apps-camogm.git", "master","" <- leave empty to get the latest, add hash to freeze ],
- change branch: edit elphel393/poky/build/conf/local.conf
ELPHEL393_branches += "elphel-apps-camogm:framepars"
