Now I use the Seeed XIAO nRF52840 Sense, a development board package downloaded on githup. But I’m getting an error in the compilation that says the file is missing floating-point operations. But I didn’t see this document on the official website https://github.com/ARM-software/CMSIS_5/tree/develop/CMSIS. How to solve this problem with help.
below is my error
