Hi,

I am doing development on an STM32F429 using CMSIS-RTOS/RTX.  I am getting the following linker error:

.\output\LmMain.axf: Error: L6200E: Symbol SysTick_Handler multiply defined (by hal_cm3.o and stm32f4xx_it.o).

Have I missed some compiler switch or something missing in my configuration?  Shouldn't I be able to write my own code for the SysTick_Handler()?Thanks,Bob

Well you can only have one, and RTOS's tend to use it to switch/manager their tasks, so you usually have to add your code to theirs.
