[yocto] bitbake cannot locate source file from recipe

[peterengcomau001 at adam.com.au]

I have had some success and some failure.
Attempt 1: FAILI changed the SRC to:FILESEXTRAPATHS_prepend :=
"${THISDIR}/files:" removing the machine name and the space. The
machine is sama5d3xek.
I still get an the error : (the directory is now changed)

'/home/lachlan/poky/build-atmel/tmp/work/sama5d3xek-poky-linux-gnueabi/linux

Note:
There is already a .bbappend file for this recipe in the original
source. Can a problem occur having two bbappend recipes each
containing FILESEXTRAPATHS_prepend := "${THISDIR}/files:" but
referring to different ${THISDIR} directories?
The existing linux-yocto-custom_3.10.bbppend file contains:KBRANCH =
"linux-3.10-at91"SRCREV = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" - i
am on a differnt computer so I wont copy the numbersPV =
"${LINUX_VERSION}+${SRCPV}"PR = "r5"FILESEXTRAPATHS_prepend :=
"${THISDIR}/files/${MACHINE}:" SRC_URI =
"git://github.com/linux4sam/linux-at91git;protocol=git;branch=${KBRANCH};nocheckout=1"SRC_URI
+= "file://defconfig"
do_deploy_append () {.......}
Attempt 2: FAIL I tried making the source file name incorrectSRC_URI
+= " file://sama5d3xek_wrong.dts "The same error results. I would have
thought it would pick up a different error if the original source file
could not be found.
Attempt 3: THIS WORKEDI also copied the following code to the
original vendor supplied .bbppend recipe, as well as moving the
sama5d3xek_lsp.dts to the correct directory for that recipeSRC_URI +=
" file://sama5d3xek_lsp.dts "
KERNEL_DEVICETREE += " sama5d3xek_lsp.dtb"

do_install_prepend () {
    cp ${WORKDIR}/sama5d3xek_lsp.dts
 ${WORKDIR}/linux/arch/${ARCH}/boot/dts
}

This worked and the device tree blob was built. However, I don't want
to modify the vendor supplied source files and would like another way
of doing this in my own layer.
Any thoughts?ThanksLachlan

 This error is a little puzzling because I can't see how you could
end up with 

"/home/lachlan/poky/build-atmel/tmp/work/sama5d3xek-poky-linux-gnueabi/linux-
 yocto-custom/3.10+AUTOINC+35158dd80a-r5/sama5d3xek/" (or more
specifically, the 
 final "sama5d3xek" subdirectory) from "${WORKDIR}/". Was this
perhaps from an 
 earlier version of the recipe?

 In any case, is "sama5d3xek" the value of MACHINE in your
configuration? If so, 
 the MACHINE value is already searched as a subdirectory of anything
in 
 FILESEXTRAPATHS, and you shouldn't then end up with that
subdirectory when the 
 file is copied into the WORKDIR. Try this instead:

 FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

 (Also, there should be no spaces in FILESEXTRAPATHS, I notice you
had a 
 trailing one in there.)

 Cheers,
 Paul
