This project is an example to show how to get the correct linux version of the Raspberry Pi (RPi) linux kernel to set up a cross-compilation environment.
This project provides the required files for the several released version of the Raspbian Raspberry Pi Linux kernel.
In cross-compilation, a compiler runs on a "host" to turn source code into executable code for a "target". When the host and the target are the same we talk about native compilation.
Issue the command "$ uname -r" on your RPi to get the version of the current linux kernel.
From your RPi, using scp or others, retrieve the files:
- /usr/share/doc/raspberrypi-bootloader/changelog.Debian.gz
- /proc/config.gz
NOTE: with new rpi kernels and distribution, if the file /proc/config.gz is missing, try:
pi@raspberrypi:~ $ sudo modprobe configs
pi@raspberrypi:~ $ zcat /proc/config.gz > raspios_kernel_$(uname -r).config
pi@raspberrypi:~ $ head raspios_kernel_5.10.17-v7+.config
#
# Automatically generated file; DO NOT EDIT.
# Linux/arm 5.10.17 Kernel Configuration
#
Put the two files in a folder named from the kernel version, at the root racine of the "getHash.sh" bash script and run the script with the linux version as argument.
Example:
$ mkdir 5.10.17-v7+
$ cp .../config.gz 5.10.17-v7+/
$ cp .../changelog.Debian.gz 5.10.17-v7+/
$ chmod a+x getHash.sh
$ ./getHash.sh 5.10.17-v7+
Then follow the instruction to create the git branch corresponding to the Linux kernel version of your RPi.
