Hi,
can anyone give me some advice how to debug an endless loop during
kernel and module recipes with my UDOO Neo support layer?
https://github.com/graugans/meta-fsl-arm-extra/tree/master-udooneo
When I build the kernel for the UDOO Neo kernel or a module with bitbake
the bitbake process hangs in an endless loop:
bitbake -v kernel-module-imx-gpu-viv
+ cd
/data/FSL/fsl-community-bsp-master/build/tmp/work/udooneo-poky-linux-gnueabi/kernel-module-imx-gpu-viv/5.0.11.p7.1+fslc+gitAUTOINC+eeeb23c0fb-r0/git
+ do_make_scripts
+ unset CFLAGS CPPFLAGS CXXFLAGS LDFLAGS
+ make CC=arm-poky-linux-gnueabi-gcc -mno-thumb-interwork -marm
-fuse-ld=bfd LD=arm-poky-linux-gnueabi-ld.bfd
AR=arm-poky-linux-gnueabi-ar -C
/data/FSL/fsl-community-bsp-master/build/tmp/work-shared/udooneo/kernel-source
O=/data/FSL/fsl-community-bsp-master/build/tmp/work-shared/udooneo/kernel-build-artifacts
scripts
make: Entering directory
'/data/FSL/fsl-community-bsp-master/build/tmp/work-shared/udooneo/kernel-source'
GEN
/data/FSL/fsl-community-bsp-master/build/tmp/work-shared/udooneo/kernel-build-artifacts/Makefile
scripts/kconfig/conf --silentoldconfig Kconfig
GEN
/data/FSL/fsl-community-bsp-master/build/tmp/work-shared/udooneo/kernel-build-artifacts/Makefile
scripts/kconfig/conf --silentoldconfig Kconfig
GEN /data/FSL/fsl-community-bsp-master/build/tmp/work-shared
For the kernel I can workaround this by adding the following line to the
recipe:
B = "${S}"
But this does not work for kernel module recipes like the
"kernel-module-imx-gpu-viv"
Maybe the cause of this issues is due to the fact that they have
included the backports subdirectory into their kernel?
https://github.com/UDOOboard/linux_kernel/tree/imx_3.14.28_1.0.0_ga_neo/backports
I already added some debugging code to the conf utility but it looks
like it does what it is supposed to do. But I guess the surrounding
Makefile is not happy.
Regards,
Christian

Hi,
Thanks to Guiseppe Pagano, there is a solution for this issue. It is
more a hot fix than a real solution but this is maybe for someone else
helpful.

I've added this to my UDOO layer in a slightly modified version:
