Kernel compile fails on “make”.\u00a0 After multiple unsuccessful attempts, cleaning the kernel tree after each attempt with:<\/p>\n
$ make clean\r\n$ make distclean\r\n$ make mrproper<\/pre>\nYou start to notice that the failure point of “make” is different each time.<\/p>\n
Cause<\/b><\/h3>\n
Memory corruption during compile.\u00a0 The memory corruption is caused by overclocking the Pi with settings that make it unstable.\u00a0 The CPU, GPU and SDRAM clock settings written to \/boot\/config.txt by the overclock applet provided in Raspbain and NOOBS provides unstable settings.\u00a0 This has been confirmed by reference to [1]<\/b> where they have carried out extensive measurements into the ideal settings for overclocking the Pi 2.<\/p>\n
Solution<\/b><\/h3>\n
Either return CPU, GPU and SDRAM clocks to safe default values and accept increased compile time (if you compile directly on the Pi) or use the settings recommended by [1].<\/b><\/p>\n
