问题
I have generated a code base using STM32Cube for STM32F205RB to be used within Atollic TrueSTUDIO. The project does not build, giving the error:
arm-atollic-eabi-gcc -c -mthumb -std=gnu90 -DUSE_HAL_DRIVER -DSTM32F205xx -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Inc -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Drivers/STM32F2xx_HAL_Driver/Inc -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Middlewares/ST/STM32_USB_Device_Library/Core/Inc -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Middlewares/ST/STM32_USB_Device_Library/Class/HID/Inc -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Drivers/CMSIS/Include -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube/Drivers/CMSIS/Device/ST/STM32F2xx/Include -IC:\Users\Elliott\Atollic\TrueSTUDIO\ARM_workspace\USBInterfaceCUBE\USBInterfaceCube\Projects\TrueSTUDIO\USBInterfaceCube Configuration/Debug/ -Os -ffunction-sections -fdata-sections -g -Wall -o Drivers\STM32F2xx_HAL_Driver\stm32f2xx_hal_rcc.o ..\..\..\..\Drivers\STM32F2xx_HAL_Driver\Src\stm32f2xx_hal_rcc.c

I'm not too sure where to go with this one - I have seen suggestions to change the compiler options, although I am unable to find where to do this within TrueSTUDIO (One thing which worries me somewhat is when I select project properties>C/C++ Build>Settings, I get an error "The currently displayed page contains invalid values" - however, I also get this same error on freshly created projects within TrueSTUDIO)
Any ideas, suggestions or clarifications are greatly appreciated!
回答1:
I experienced the same problem, I fixed it by adding -mcpu=cortex-m3
回答2:
In this IDE you must set the uC in the project/right_click/properties. Then it will know what to set in the -mcpu gcc option.

After much stuffing about, I believe I have found the root of the problem - the startup script generated by STM32Cube is for MDK-ARM (I have double checked - I certainly have TrueSTUDIO selected with Cube, looks like a bug?). I can get my code to compile without any errors by creating a new project within TrueSTUDIO and copy/pasting the .s file from that project over the Cube generated project.
Looking at the top of startup_stm32f205xx.s, I can see the line below:
;* Description : STM32F205xx devices vector table for MDK-ARM toolchain.
The correct file mentiones TrueSTUDIO:
* @brief STM32F2xx Devices vector table for Atollic TrueSTUDIO toolchain.

I had this problem. Check the configuration settings to see if your STM device is installed. I must change my stm
