Compiling SD bootloader

Controllers Smoothie
1

I have added a relay to p2_11 which turns on with logic zero to optocoupler input.

I added this line to main.c in bootlader

GPIO_init(P2_11); GPIO_output(P2_11); GPIO_write(P2_11, 1);

to turn off the relay when bootloader starts and not turn on relay accidentally if smoothie fails to start

but i dont have any experience in compiling the modified code

need help

The bootloader can take very little extra code as it is already preyy much near the maximum size it can be. So I suggest you find an alternative way to do what you want, ot find a way to reduce the size of the bootloader, or make the bootloader use more flash and change the start address of smoothie.
