Trying create a programming script recipe and need to find out the

so I can get the filename of the image
${MACHINE}-${IMAGE_BASENAME}.ubi
I.E: if I do
$ MACHINE=beagleboard bitbake some-image
and "some-image_1.0.bb" contains
IMAGE_BASENAME = "renamed-image"
Then the resulting image will be
"beagleboard-renamed-image.ubi"
How get this info from another recipe?
You can't. The way to handle this is as part of do_rootfs itself (e.g. from a
script called from ROOTFS_POSTPROCESS_COMMAND or IMAGE_POSTPROCESS_COMMAND).

OK, thanks
I tried to define "configure-sam-ba.bbclass" which is inherited by my
image.
configure-sam-ba.bbclass:
----------------------------------------------------------------------------------------------------------
SCRIPTFILE_TEMPLATE = "${DEPLOY_DIR_IMAGE}/scripts/${MACHINE}.tcl"
SCRIPTFILE =
"${DEPLOY_DIR_IMAGE}/scripts/${IMAGE_LINK_NAME}-${MACHINE}.tcl"
PROGFILE_TEMPLATE = "${DEPLOY_DIR_IMAGE}/scripts/prog.sh"
PROGFILE =
"${DEPLOY_DIR_IMAGE}/scripts/prog-${IMAGE_LINK_NAME}-${MACHINE}.sh"
sam-ba_setup () {
if [ -e ${PROGFILE_TEMPLATE} ] ; then
sed -i s/#MACHINE#/${MACHINE}/ ${PROGFILE_TEMPLATE}
sed -i s/#IMAGE#/${IMAGE_LINK_NAME}/ ${PROGFILE_TEMPLATE}
fi
cp ${PROGFILE_TEMPLATE} ${PROGFILE}
if [ -e ${SCRIPTFILE_TEMPLATE} ] ; then
sed -i s/rootfs.ubi/${IMAGE_LINK_NAME}-${MACHINE}/
${SCRIPTFILE_TEMPLATE}
fi
cp ${SCRIPTFILE_TEMPLATE} ${SCRIPTFILE}
}
EXPORT_FUNCTIONS sam-ba_setup
EXTRA_IMAGEDEPENDS_append_mymachine = ' sam-ba'
IMAGE_POSTPROCESS_COMMAND_append_mymachine = " sam-ba_setup; "
----------------------------------------------------------------------------------------------------------
myimage.bb: contains.
inherit configure-sam-ba
----------------------------
It appears that the "configure-sam-ba.bbclass" file is found.
If I change the filename in the inherit statement I get an error message.
inherit configure-sam-ba-x
I get an error message.
Another indication is that the call to "sam-ba_setup;" is inserted in
the "run.do_rootfs.*" script,
but the script does not contain the "sam-ba_setup" subroutine.
In some places IMAGE_POSTPROCESS_COMMAND contains "
rootfs_update_timestamp ",
from image.bbclass which *is* included in the "run.do_rootfs.*" script.
Should you not be able to use commands from a bbclass as
PRE/POSTPROCESS_COMMAND?
A standard shell command will work, but since I need a number of
commands, it seems
cleaner to implement it in a bbclass file.
This is my first bbclass file, so there may be things, I don't understand...
