use your custom image recipe as before to just produce your root- filesystem which results in a (compressed) tar-file in ${DEPLOY_DIR_ IMAGE}. It will be referenced from the genimage recipe without any file extension via GENIMAGE_ROOTFS_IMAGE. Now your UBI-recipe (e.g. 'your- customized-ubi.bb') could look like inherit genimage LICENSE = "MIT" LIC_FILES_CHKSUM = "file://${COREBASE}/meta/files/common-licenses/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302" SRC_URI += "file://genimage.config" # to not confuse the flashable UBI-image ('ubi') # with the UBI-filesystems ('ubifs') it contains GENIMAGE_IMAGE_SUFFIX = "ubi" # the name of the root-filesystem genimage should use GENIMAGE_ROOTFS_IMAGE = "your-customized-rootfs" with the accompanying 'genimage.config' for example as follows # # Manufacturer ID: 0x2c, Chip ID: 0xda # -> Micron MT29F2G08ABAEAWP # 256 MiB, SLC # flash nand { pebsize = 131072 lebsize = 126976 numpebs = 2044 minimum-io-unit-size = 2048 sub-page-size = 2048 } image @IMAGE@ { flashtype = "nand" ubi { } partition rootfs { image = rootfs.ubifs size = 64MiB } partition opt { image = opt.ubifs size = 32MiB } partition data { image = data.ubifs autoresize = true } } image rootfs.ubifs { flashtype = "nand" ubifs { extraargs = "-x lzo" max-size = 64MiB } mountpoint = "/" } image opt.ubifs { flashtype = "nand" ubifs { extraargs = "-x lzo" max-size = 32MiB } mountpoint = "/opt" } image data.ubifs { flashtype = "nand" ubifs { extraargs = "-x lzo" max-size = 192MiB } mountpoint = "/data" } In a UBI-image almost all UBI-volumes need to have a fixed size and only one is allowed to use the autoresize mechanism which blows it up to use the remaining space when it is UBI-attached for the first time. Distinct from that is the UBI-filesystem's max-size parameter which prescribes the maximum size of an UBI-volume that shall be addressable by this filesystem. This means that if you would re-use 'data.ubifs' in a volume that has been autoresized to e.g. 1024MiB the filesystem would not be able to make use of it. I neither tested the recipe nor the genimage.config, so please give some feedback.
