Download Source Files
Please refer to the A Guide to Downloading and Compiling SP7350 Code for downloading and compiling the source files for the SP7350 platform.
Configure Build Environment (create linux/kernel/.config)
For example, to configure the build environment for booting from an SD card and using BusyBox for the SP7350 Ev board:
...
After making your selections, the system will configure the build environment. This may take several seconds to minutes depending on your computer's performance. Please wait for the process to complete.
Build Code (create linux/kernel/Module.symvers)
Once configurations are set, initiate the build process with the following command:
...
This command ensures that make uses English language settings. The build process will compile the code based on your configurations, typically taking a few minutes. Please be patient and let the build complete.

Install Linux kernel-headers
Before using the Linux kernel headers, copy the linux-headers-5.10.201 folder to /usr/src/ on your target board. Refer to report of ll command in Ubuntu where linux-headers has been copied to:
