If we change the 'sdcard' to 'sdcard.bz2' in IMAGE_FSTYPES it just works. Using: IMAGE_FSTYPES = "tar.bz2 ext3 sdcard.gz" I got: otavio@centrium ~/src/ossystems/yocto/build % ls tmp/deploy/images/imx6qsabresd -l total 26544 ... -rw-r--r-- 1 otavio otavio 7438938 Dec 9 16:32 core-image-minimal-imx6qsabresd-20141209182116.rootfs.sdcard.gz ... So this patch is not required.
hello, I want also to get a compressed sdcard image out of the Build, following with you suggestion by setting : IMAGE_FSTYPES = "tar.bz2 ext3 sdcard.gz" I get in the fac an *-image.rootfs.sdcard.bz2 but this image is missing the rootfilesystem and wont' work please check image_types_fsl.bbclass something should be wrong there. 2014-12-09 19:39 GMT+01:00 Otavio Salvador <otavio@ossystems.com.br>: > On Mon, Dec 1, 2014 at 1:38 PM, info <info@embexus.com> wrote: > > Add compression method to apply to SDCARD after it has been created. > > Supported formats are "gzip", "bzip2" or "xz".

Add compression method to apply to SDCARD after it has been created. Supported formats are "gzip", "bzip2" or "xz". The original .sdcard file is kept and a new compressed file is created if one of these compression formats is chosen. SDCARD_COMPRESSION can be defined in local.conf and only one compression method among the supported formats can be set. If SDCARD_COMPRESSION is set to any other value it is silently ignored.
