Inorder to build a developer package, i am following the link : https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package

I am not able to apply the patch to the linux kernel. 

when i try to apply patches the terminal is stuck

Hi @Vthul​ 

In order I can help can you please confirm you are at step "5.2.2 Building and deploying the Linux kernel for the first time" of the wiki.

You refer to the README.HOW_TO.txt ?

Can you please share exactly the steps you have followed ? Are you doing installation in build directory or in source path ?

Can you share a screen copy of the command freezing the terminal ?

Thx

Olivier

Hi @Community member​ ,

Thanks for your reply.

In order I can help can you please confirm you are at step "5.2.2 Building and deploying the Linux kernel for the first time" of the wiki.

You refer to the README.HOW_TO.txt ? ---Yes

I am following the README.HOW_TO.txt.

I have extracted the Linux files and obtained the patches.

So the step is to apply the patches before compiling if i am not wrong.

To apply patches, i am doing this

So in 3rd point ---> $> for p in `ls -1 <path to patch>/*.patch`; do patch -p1 < $p; done

 and i get as in above screen shot

<path to patch> i am already in current working directory as that of the linux Kernel

I looks you are not in the correct directory to apply the patch.

you should be in (..)sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9

and use this command : $for p in `ls -1 ../*.patch`; do patch -p1 < $p; done 

Also, are you in shell compatible with SDK cross-compilation ?

If not please do this before any other command :

$source [Developer_Package_Path]/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_weston-linux-gnueabi

Hope it help

Hello ,

Also, are you in shell compatible with SDK cross-compilation ? -> yes

and use this command : $for p in `ls -1 ../*.patch`; do patch -p1 < $p; done - this worked .
