Set the environment:

• For Pi 3 32-bit: source ./yocto-poky/oe-init-build-env ./rpi3-build/

• For Pi 3 64-bit: source ./yocto-poky/oe-init-build-env ./rpi3-64-build/

• For Pi 0 : source ./yocto-poky/oe-init-build-env ./rpi0w-build/

To use a 4.14.x PREEMPT-RT kernel, modify conf/local.conf and adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-raspberrypi-rt"

To use a 4.9.x PREEMPT-RT kernel instead, adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-raspberrypi-rt" `PREFERRED_VERSION_linux-raspberrypi-rt := "4.9%"

To use a 4.9.x I-pipe/Xenomai kernel, modify conf/local.conf and adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-raspberrypi-ipipe"

• rpi-hwup-image-rt (same as rpi-hwup-image buth with PREEMPT-RT kernel and rt-tests suite);
• rpi-basic-image-rt (same as rpi-basic-image but with PREEMPT-RT kernel and rt-tests suite);
• rpi-hwup-image-xenomai (same as rpi-hwup-image buth with I-pipe/Xenomai kernel, rt-tests and Xenomai suite);
• rpi-basic-image-xenomai (same as rpi-basic-image buth with I-pipe/Xenomai kernel, rt-tests and Xenomai suite).

Note: to use *-rt image, be sure to set PREEMPT-RT kernel as specified in previous section.

Note (2): to use *-xenomai image, be sure to set I-pipe/Xenomai kernel as specified in previous section.

Set the environment:

source ./yocto-poky/oe-init-build-env ./beaglebone-build/

To use a 4.14.x PREEMPT-RT kernel, modify conf/local.conf and adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-yocto-rt"

To use a 4.9.x I-pipe/Xenomai kernel, modify conf/local.conf and adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-yocto-ipipe"

• beaglebone-hwup-image-rt (same as core-image-minimal buth with PREEMPT-RT kernel and rt-tests suite);
• beaglebone-basic-image-rt (same as basic-image but with PREEMPT-RT kernel and rt-tests suite);
• beaglebone-hwup-image-xenomai (same as core-image-minimal buth with I-pipe/Xenomai kernel, rt-tests and Xenomai suite);
• beaglebone-basic-image-xenomai (same as basic-image buth with I-pipe/Xenomai kernel, rt-tests and Xenomai suite).

Note: to use *-rt image, be sure to set PREEMPT-RT kernel as specified in previous section.

Note (2): to use *-xenomai image, be sure to set I-pipe/Xenomai kernel as specified in previous section.

Set the environment:

source ./yocto-poky/oe-init-build-env ./olinuxino-build/

To use a 4.14.x PREEMPT-RT kernel, modify conf/local.conf and adds:

PREFERRED_PROVIDER_virtual/kernel := "linux-mainline-rt"

• olinuxino-hwup-image-rt (same as core-image-minimal buth with PREEMPT-RT kernel and rt-tests suite);
• olinuxino-basic-image-rt (same as basic-image but with PREEMPT-RT kernel and rt-tests suite);

Note: to use *-rt image, be sure to set PREEMPT-RT kernel as specified in previous section.
