Building an image using yocto for t4240 - and qemu emulation

[vigneshwarensan]

I used the yocto build to generate images for t4240.

I downloaded the meta-fsl-ppc layer (from: meta-fsl-ppc - Layer containing Freescale PPC hardware support metadata)

and included it into the build and removed the meta-yocto-bsp layer.

The build generated a few images in tmp/deploy/images/t4240qds.

The build was successful, but while I attempted to run using qemu, it failed.

                    $ runqemu t4240qds

PS: I saw the images folder and I didnt find a .ext3 filesystem, instead I found a rootfs.tar.gz file.

Can I run a t4240 image in qemu?

Thanks in advance.

The SDK Yocto build environment doesn't support runqemu, KVM/qemu virtualization should be implemented on the target board.

The rootfs type can be customized by setting the IMAGE_FSTYPES variable in the

above recipes.

Supported rootfs types include the following:

cpio

cpio.gz cpio.xz

cpio.lzma

cramfs

ext2

ext2.gz

ext2.gz.u-boot

ext2.bz2.u-boot

ext3

ext3.gz.u-boot

ext2.lzma

jffs2

live

squashfs

squashfs-lzma

ubi

tar

tar.gz

tar.bz2

tar.xz
