Hi,
I made tests with LTO option activated on stm32mp15 boards but if have a issue
with the U-Boot target "u-boot-initial-env" (this command used by YOCTO)
$> make u-boot-initial-env
...
GENENV u-boot-initial-env arm-none-linux-gnueabihf-objcopy: env/common.o: can't dump section '.rodata.default_environment' - it does not exist: file format not recognized sed: can't read u-boot-initial-env: No such file or directory make[1]: *** [/local/home/frq07632/views/u-boot/Makefile:2315: u-boot-initial-env] Error 2 make[1]: Leaving directory '/local/home/frq07632/views/build/stm32mp15_defconfig' make: *** [Makefile:177: sub-make] Error 2
But I reproduced it with sandbox:
$> make sandbox_defconfig
$> make all
$> make u-boot-initial-env
....
LTO u-boot OBJCOPY u-boot-nodtb.bin COPY u-boot.bin GENENV u-boot-initial-env objcopy: env/common.o: can't dump section '.rodata.default_environment'
- it does not exist: file format not recognized
sed: can't read u-boot-initial-env: No such file or directory make: *** [Makefile:2315: u-boot-initial-env] Error 2
Do you already know this issue for other board which activate the LTO feature ?
I don't see any remarks about this issue on mailing list.
Today I am known how to solve this issue.
PS: The same command is executed in "scripts/get_default_envs.sh"
Seems that that script isn't executed in code integration, otherwise I would have noticed this.
