How To apply patches when installing the kernel? (Developer Package)

SigmaPrime · ‎2020-12-04

Hello Everyone

I am using the README.HOW_TO.txt file to install the kernel. IN section 3 it is stated that I must apply some patches:

1-Section 3 patch application

if there is some patch, please apply it on source code
    $> for p in `ls -1 *.patch`; sudo do patch -p1 < $p; done

can't find file to patch at input line 16
Perhaps you used the wrong -p or --strip option?

How do I do that ? Can you give me an example?

I am working in the following directory which contains patches that I will link in a picture.

Directory :

~/DevPack/stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12/sources/arm-ostl-linux-gnueabi/linux-stm32mp-5.4.56-r0

2- section 4: have a better management of the kernel

Now coming to section 4 of the .txt file. It is written that I have to:

test -d .git || git init . && git add . && git commit -m "new kernel" && git gc

But I get the following error even with sudo:

/home/mehdi/DevPack/stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12/sources/arm-ostl-linux-gnueabi/linux-stm32mp-5.4.56-r0/.git: Permission denied

Best regards :grinning_face:
