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
