Most smartphones and smartwatch already have a built-in operating system, so they don’t really support FreeRTOS. Embedded OS’s like FreeRTOS are not really normal targets to adapt a “popular” (by which I assume you mean something that runs on a full OS system) application. ---

i noticed that the UNISOC will support some chinese popular APP like QQ, Wechat. whether these extended application support mostly by the chipset manufactures which sell the chipset with RTOS?
