I have enabled SPI on my Raspberry Pi 3, and want to know why the mode for physical pins 24 and 26 are set to Mode 'OUT' and not 'ALT0'. According to the documentation here and here the mode of all of these pins should be 'ALT0'. So what is the deal?
Here is a screen shot when I execute 'gpio readall' from the commandline.
If I execute the command 'gpio mode 10 alt0' it does change the mode of physical pin 24 to 'ALT0', but when I reboot, or cycle power (after a graceful shut down), the mode changes back to 'OUT'.
