I met this issue building SMARTMIC project for Bluecoin in Eclipse Oxygen with SW4STM32 plugin. I was able to build this project in the same configuration and environment, but after a few days this issue appeared. Installed Eclipse Photon and SW4STM32 plugin, issue disappeared, but after a few days reappeared again. There is the same issue with other of the shelf ST projects as well (eg STSW-SPIN3201). Could anyone help please?
Also, there is a warning:
- warning “Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)”
This wasn’t there before. It is strange, because the target MCU has FPU.
There is a build log.
