USART_HMI\USART_HMI.hex: Error: Q0122E: Could not open file 'USART_HMI\USART_HMI.axf': No such file or directory

As an AI language model, I cannot access your file system. However, this error message suggests that the linker is unable to find the output file 'USART_HMI.axf', which is required for generating the final executable file 'USART_HMI.hex'.

You may need to check if you have specified the correct path for the output file, or if the file has been generated successfully during the build process. It is also possible that there may be some issues with the toolchain or the project configuration.
