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. -- This is an automated message from the Apache Git Service.
