My next problem though is due mostly to an unfamiliarity with building
According to jumpnow's article on the button and LED controls
in order to use GPIO21 and GPIO22 as GPIO and not as LEDs (I will not be
using an expansion board on the final implementation) I have to disable
CONFIG_LEDS_GPIO in the kernel and rebuild it.
I have never built a kernel (though I have read through the yocto getting
started) and as such am struggling with what exactly I need to do to disable
CONFIG_LEDS_GPIO and would appreciate any information that can be provided.
While I'm in the process of modifying the kernel/u-boot parameters I would
also like to disable/remove the Wi/Fi, Bluetooth, and Touch Screen
configurations as we will only be using the console port and an ethernet
connection and as fast a boot time as is possible is desired.
