[meta-freescale] Help with variable expansion in bbappend

[Alex Gonzalez]

Hi,

I am stuck with a problem I don't seem able to debug.

I am using the denzil branch of meta-fsl-arm, and I am overriding some
recipes on a different layer. For example I have a
linux-libc-headers-imx_2.6.35.3.bbappend recipe that looks like:

PR_append = "+custom.0"

SRCREV_mx5 := "mybranch"
SRC_URI_mx5 := "git://myworking.git.server/linux-2.6.git"

do_fetch_prepend() {
        bb.warn("[AG] SOC family " + d.getVar('SOC_FAMILY', True))
        bb.warn("[AG] SRC_URI " + d.getVar('SRC_URI', True))
}

When I do:

bitbake -e linux-libc-headers | grep SRC_URI
# SRC_URI=git://git.freescale.com/imx/linux-2.6-imx.git
SRC_URI="git://git.freescale.com/imx/linux-2.6-imx.git"
# SRC_URI_mx5=git://myworking.git.server/linux-2.6.git
SRC_URI_mx5="git://myworking.git.server/linux-2.6.git"

This seems to imply the overriden SRC_URI will be used.

But when I try to build I get:

NOTE: Running task 234 of 441 (ID: 4,
/home/alex/Projects/meta-fsl-arm/recipes-kernel/linux-libc-headers/linux-libc-headers-imx_2.6.35.3.bb,
do_fetch)
NOTE: package linux-libc-headers-imx-2.6.35.3-r6+custom.0: task
do_fetch: Started
WARNING: [AG] SOC family mx5
WARNING: [AG] SRC_URI git://git.freescale.com/imx/linux-2.6-imx.git
ERROR: Function failed: Fetcher failure for URL:
'git://git.freescale.com/imx/linux-2.6-imx.git'. Please set SRCREV to
a valid value

So it is trying to use the original SRC_URI, even though the
SOC_FAMILY is set to mx5.

Any idea as to why is this happening or where to debug next?

Thanks in advance,
Alex
