Configure kernel source code failed

[tpeng.1]

Following the instruction from https://github.com/STMicroelectronics/meta-st-stm32mp/blob/thud/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt

* Configure on a build directory (different of kernel source code directory)   Here for example, build directory is located at the same level of kernel   source code   $> cd <directory to kernel source code>   $> mkdir -p ../build

$> make ARCH=arm O="$PWD/../build" multi_v7_defconfig fragment*.config

Then got the following message

Unsuccessfully, need your help.

Hi @tpeng.1​ 

The document you refer has been properly validated on Ubuntu 16.04 and 18.04 Linux system.

Are you using other OS for your Host ?

Else please check you didn't miss any steps.

Hi Olivier,

Thank your quick reply!

Yes, I missed some steps.

It works now after rechecking build processure.

Reviving this thread to add what actually fixed this issue for me. I forgot to start the SDK on my host machine (source)

cd $HOME/STM32MPU_workspace/STM32MPU-Ecosystem-v6.0.0/Developer-Package 
source SDK/environment-setup-cortexa35-ostl-linux
