Line 113: − ===Frequently Questions=== − − *disagrees about version of symbol module_layout − − After the system has been booted, <code>dmesg</code> can see this error reported when the driver of camera is loaded. It is caused by the mismatch between the original piOS version on the board and the compiled camera driver version. − − It is recommended to refer to this [https://www.raspberrypi.com/documentation/computers/linux_kernel.html#cross-compiling-the-kernel link] to recompile from the code and install Image, dtb, modules as a whole.

The main resources in this section are the [https://www.raspberrypi.org/documentation/linux/kernel/building.md official piOS building method]. We use the method of cross-compilation.
The main resources in this section are the [https://www.raspberrypi.org/documentation/linux/kernel/building.md official piOS building method].
We provide methods to compile locally on Raspberry Pi and cross-compile on PC. It is recommended to use Raspberry Pi local compilation, which is simpler and faster.
