I have encountered a error while trying to do build for my cmake file

cmake\_minimum\_required (VERSION 3.0.0)  
set(CMAKE\_SYSTEM\_NAME Generic)  
set(CMAKE\_SYSTEM\_PROCESSOR arm)  
set(CMAKE\_C\_COMPILER arm-none-eabi-gcc)

set(STM32CUBE\_CMSIS\_PATH “C:/Users/rsridx/Downloads/edge\_torch\_remote-main/Advanced/Drivers/CMSIS”)  
set(FREERTOS\_PATH “C:/Users/rsridx/Downloads/edge\_torch\_remote-main/Advanced/Middlewares/Third\_Party/FreeRTOS”)

target\_link\_libraries(Test -Wl,–start-group -lgcc -lc -lm -lrdimon -Wl,–end-group  
)  
set\_target\_properties(Test PROPERTIES SUFFIX “.elf”)  
add\_custom\_command(TARGET Test POST\_BUILD  
COMMAND ${CMAKE\_OBJCOPY} -O ihex $\<TARGET\_FILE:Test\> ${CMAKE\_CURRENT\_BINARY\_DIR}/Test.hex  
COMMAND ${CMAKE\_OBJCOPY} -O binary $\<TARGET\_FILE:Test\> ${CMAKE\_CURRENT\_BINARY\_DIR}/Test.bin  
)

Later I came to know that the ARM cortex is not specified in the cmake flags  
**set(CMAKE\_C\_FLAGS “${CMAKE\_C\_FLAGS} -mcpu=cortex-m4 -mthumb -mno-thumb-interwork -mfpu=fpv4-sp-d16 -mfloat-abi=hard”)**  
**set(CMAKE\_CXX\_FLAGS “${CMAKE\_CXX\_FLAGS} -mcpu=cortex-m4 -mthumb -mno-thumb-interwork -mfpu=fpv4-sp-d16 -mfloat-abi=hard”)**  
**set(CMAKE\_ASM\_FLAGS “${CMAKE\_ASM\_FLAGS} -mcpu=cortex-m4 -mthumb -mno-thumb-interwork -mfpu=fpv4-sp-d16 -mfloat-abi=hard”)**

This has resolved my issue! 😀
