(Created page with "<includeonly> As mentioned above, the wic image only supports booting from an SD card. To flash an image to NAND, Variscite provides an image '''{{{var-recovery-recipe}}}''', which inherits '''var-default-image''' and adds the following files needed for installing to eMMC: {{AM33_RECOVERY_SD_FILES}} By default, the image will be named '''{{{var-recovery-recipe}}}-{{#var:MACHINE_NAME}}.wic.zst'''.

Being the image designed to burn eMMCs, in order to burn the NAND, the following override is required | |||
echo 'RECOVERY_SD_NAME="VAR_RECOVERY_TARGET_ROOTFS_TYPE ?= "ubi"' >> conf/local.conf | |||
The var-default-image is not suitable for NANDs of 256 MB. | |||
It's possible to further customize the image '''{{{var-recovery-recipe}}}''', providing a dedicate image for the NAND and reducing the final image size. For example | |||
echo 'VAR_RECOVERY_TARGET_ROOTFS ?= "var-thin-image"' >> conf/local.conf | |||
echo 'VAR_RECOVERY_IMAGE_ROOTFS_MAXSIZE ?= "${@eval('3700*1024')}"' >> conf/local.conf | |||
By default, the image will be named '''{{{var-recovery-recipe}}}-{{#var:MACHINE_NAME}}.wic.zst'''. It can be overridden adding the '''RECOVERY_SD_NAME''' variable to local.conf.
