I got a error during setting coder.config like below
error message is "Unable to find the STM32CubeMX project file. Either selected project file does not exist or incorrect file is selected.
Use help codegen for more information on using this command."
I am trying to make a code for my embeddedboard stm32h7, with matlab coder.
but.. failed
How i can generate c-code for embeded board in matlab coder ( not simulink )

fprintf(' -> C 코드 생성 성공!\n');
catch e
fprintf('!!! 코드 생성 중 오류 발생 !!!\n');
rethrow(e);
end
