Compiling and Updating Linux Kernel

Perform the following steps to compile and update Linux kernel:

1. Install dependencies to build kernel:

   apt-get install build-essential linux-source bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev dwarves bison git

2. Clone the kernel from StarFive Github:

   git clone https://github.com/starfive-tech/linux

3. Checkout the desired Kernel version:

   git checkout <Tag Version>

4. Build the kernel with bindeb-pkg:

   cd linux/
   cp arch/riscv/configs/starfive_visionfive2_defconfig .config
   make ARCH=riscv olddefconfig
   make ARCH=riscv -j$(nproc) bindeb-pkg

5. Once the compile is finished, install the .deb Kernel packages.

   dpkg -i *.deb

   Note: Currently the dtbs are not synced once you installed a different version of kernel, you'll need to copy over the dtbs from /usr/lib/linux-image-<custom version>/starfive to /boot/dtbs/
