This repository features a 'No SD card' version of Smoothieware, which adds a new device target; lpc1768_NOSD, this disables the SD card code, and links the output file with a new linker script.

This fork has been built with inspiration from;

• https://github.com/nullsub/Smoothieware
• https://gist.github.com/nullsub/10f4551eb0f3e2422409

To build the 'No SD card' target, run;

DEVICES=lpc1768_NOSD make -j8 all

To flash (using lpc21isp), run;
