Build images

Central Compute Node

• cd CarIQ/build-ccn
• source ../yocto/poky/oe-init-build-env .
• bitbake cariq-ccn-image
• If the build is successful, you can find the SD Card Image in following path:
  • CarIQ/build-ccn/tmp/deploy/images/khadas-vim3/cariq-ccn-image-khadas-vim3.wic.bz2

Edge Node X (where, X = 1, 2)

• cd CarIQ/build-enX
• source ../yocto/poky/oe-init-build-env .
• bitbake cariq-en1-image
• bitbake cariq-en2-image
• If the build(s) are successful, you can find the SD Card Image in following path:
  • CarIQ/build-en1/tmp/deploy/images/raspberrypi5/cariq-en1-image-raspberrypi5.rootfs.wic.bz2
  • CarIQ/build-en2/tmp/deploy/images/raspberrypi5/cariq-en2-image-raspberrypi5.rootfs.wic.bz2
