   Creating the graphics driver is normally not a huge job if you have 
   proper specifications.  According to 
   https://www.qualcomm.com/products/snapdragon-wear-3100-platform
   
   GPU    GPU Name: Qualcomm® Adreno™ 304 GPU
                API Support: OpenGL® ES 3.0
   
   https://en.wikipedia.org/wiki/Adreno (Hmmm... Adreno is an anagram of 
   Radeon).
   
   It looks like the interface to the display is MIPI.  I don't know what 
   that GPU internal interface is.  Creating a graphics driver would 
   probably be a significant effort .
   
   I don't know how much about the OpenGL details.    Providing the OpenGL 
   interface would mostly likely be a large effort too.
   
   The only good news I see is:
   
   CPU    CPU Clock Speed: Up to 1.2 GHz
                CPU Cores: 4x ARM Cortex A7, Quad-core CPU
                CPU Architecture: 32-bit
   
   Cortex A7 is well supported by NuttX so the basic port to the Snapdragon 
   part might not be too difficult.
   
   I don't see any low effort way to get NuttX on that platform. You could 
   consider some of the other supported platforms like Beaglebone Black 
   (AM335x, Cortex A8 signle core), i.MX6 (quad core cortex a7 but no 
   graphics support yet), or possibly others.
