It is possible to build only the needed module and insmod/rmmod, but in case of a crash followed by a rebooting, the developer loses its work environment. On a decent computer (i7 5600U), the build/test cycle lasts about 30 minutes. But this method will quickly reach its limitations to write new kernel code. It works, and one can easily build a kernel and install it, with all peripheral working. For example, the Ubuntu kernel build instructions can be found at. So my second step was to use a distribution specific build procedure. After booting, I always had some non working peripherals. Before doing linux kernel development, I started by typing make in a kernel tree. ![]()
