You will first be guide to install the Linux® kernel source code in the Developer Package directory. Then step by step you will execute procedures to modify, rebuild and reload the Linux® kernel.
2. Download the the Linux® kernel source[edit source]
- Download the STM32MP15-Ecosystem-v1.0.0 Developer Package Sources in your $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/Developer-Package directory
- Uncompress the tarball file to get the Linux kernel (Linux kernel source code, ST patches, ST configuration fragments...)
cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/Developer-Package tar xvf SOURCES-stm32mp1-openstlinux-4.19-thud-mp1-19-02-20.tar.xz
3. Prepare the Linux® kernel source[edit source]
cd stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/ tar xvf linux-4.19.9.tar.xz
