cubeMX generation problem Posted by tang on 2016-04-11 10:58 Hi Dave, To me, it seems that the startup file (startup_stm32xxxxx.s) is missing from your project. Can you try to copy it from the folder generated by CubeMX (into Drivers\CMSIS\Device\ST\STM32Xxxx\Source\Templates\gcc) into your project. Hope my guess it correct. Kevin.
