I Cannot Build A UBIFS Root File System in SDK 1.2/P1010

[augustuschen]

Hi,

I would like to use ubifs as the rootfs. The CPU is P1010, SDK is 1.2 yocto. According to the documentations in SDK, I modified

(1) the "IMAGE_FSTYPES" in <sdk_path>/meta-fsl-ppc-private/images/fsl-image-flash.bb,

(2) and then "bitbake fsl-image-core" to build a rootfs image.

There is not any error message during listed process. So I think I should find an image in <sdk_path>/build_p1010rdb_release/tmp/deploy/images be named fsl-image-core-p1010rdb-yyyymmddhhmmss-rootfs.ubifs, but I cannot. However, I DO find a ubinize.cfg in this folder.

Is there anyone knows how should I do to make a rootfs in ubifs?

This (ubifs) is not tested in Freescale's SDK.

How to know what is tested? Is there a document indicating? Thanks.

The default build images on the targets we provided (fsl-image-minimal,core,lsb-sdk) should all be tested. That being said, getting ubifs to work should not be all that much effort but I can't comment on exactly what's needed at this point.

I suspect you might be missing user space tools to create ubi file systems from a Linux host, something equivalent to mkfs.ubifs for example.
