Step 4. Add meta-st-mems1 layer
PC $> bitbake-layers add-layer ../layers/meta-st/meta-st-mems1
Step 5. Update the configuration to add new components in the image
PC $> echo 'IMAGE_INSTALL:append = "mems1"' >> ../layers/meta-st/meta-st-openstlinux
/conf/layer.conf
or
PC $>vi ../layers/meta-st/meta-st-openstlinux/conf/layer.conf
IMAGE_INSTALL: append = "mems1"
Step 6. Build the image
PC $> bitbake st-image-weston
New Images are formed in the tmp-glibc/deploy/images/stm32mp1/ directory
PC $> ls -l tmp-glibc/deploy/images/stm32mp1/FlashLayout_sdcard_stm32mp157f-dk2-trus
ted.tsv
and FlashLayout_sdcard_stm32mp157f-dk2-trusted are created besides other images.
