I have a project which was completed by another persion by using uvision 3. Recently I plan to add some new fuctionalities in this project. Since I only have uvision 4 on my machine, so, I plan to use uvision 4 to open the project and see if I can complie the project.
Without touching anything of the source and header files, I opened this project using uvison 4. However, when I compiled this project, there was an error message, "_swi_0 multiply defined in hal.o and rtx_config.o".
Is it caused by the toolchain upgrade? could anyone help on this issue?
Thanks a lot!
The hardware platform is LPC 2103 (Arm-7 core based) RTOS: keil MDK RTOS
