Setup environment
Get sources and build default images: Instructions
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.
