[yocto] Problem with exporting variable in bbappend file

[Gujulan Elango, Hari Prasath (H.)]

Hello all,


We are working on a platform based on Renesas processor. The BSP provided by them has arm-trusted-firmware. Now in order to enable all the 8 cores, they have suggested to add a environment variable in the arm-trusted-firmware_git.bb file in their BSP layer as below.


export PSCI_DISABLE_BIGLITTLE_IN_CA57BOOT="0"


We would prefer to make this change in our custom layer by creating a .bbappend file. We added the change in bbappend file,recompiled it and tested, but couldn't get the expected results. When I do the same change in the .bb file itself in their BSP layer, I am able to see the expected result.


Is it okay to just add the export as mentioned above in the .bbappend file ? Am I missing something else ?


Thanks & Regards,

Hari Prasath
