Delete unused hob images

Delete unused hob images

Hi,

I read this section in Poky Reference manual:

*A.2.13. build/tmp/deploy/images/*
*
*
*This directory receives complete filesystem images. If you want to flash
the resulting image from a build onto a device, look here for the image.*
*
*
*Note, you should not remove any files from this directory by hand in an
attempt to rebuild an image. If you want to clean out the cache, re-run the
build using the following BitBake command: *
*     $ bitbake -c cleanall <target>*

I built many images using hob and in my *build/tmp/deploy/images/ *folder
there are a lot of rootfs images (like
hob-image-imx53qsb-<timestamp>.rootfs.ext3 etc..) and I want to remove the
unused ones to free some space..

I tried tp run:

*bitbake -c cleanall * hob-image-imx53qsb-<timestamp>

but I got:
ERROR: Nothing PROVIDES 'hob-image-imx53qsb-<timestamp>'

Can I safely remove these files by hand?

thanks

Giovanni

I'm not sure where this came from originally, but it is not correct. I'll talk 
to Scott R about fixing this part of the manual.

The hob-image-*, yes. In fact any actual image files in deploy/images are OK to 
delete (excluding *zImage*, *uImage*, etc. - those are kernels). All the 
warnings are trying to prevent is people deleting the entire contents of 
deploy/images and then wondering why the kernel, bootloader etc. that get 
produced as part of the process of building an image but are not part of the 
image itself aren't re-created when they build the image again afterwards.

Cheers,
Paul
