Build Project: sorry, unimplemented: Thumb-1 hard-float VFP ABI

Posted by random.registration on 2016-07-12 09:49

Hi,

got a fresh STM32F767 Nucleo-144 Board, installed STM32CubeMX-4.15.1, sw4stm32_win_64bits-v1.8 and tried some of the examples in the STM32Cube_FW_F7_V1.4.0 package but none of them are working.

I followed the instructions in the documentation, i.e. switch workspace, select example and import project but when i select build project i always got the same error messages:

Description Resource Path Location Type
make: *** Example/User/main.o Error 1 STM32F767ZI-Nucleo C/C++ Problem

Description Resource Path Location Type
sorry, unimplemented: Thumb-1 hard-float VFP ABI STM32F767ZI-Nucleo line 81, external location:

The first message can be solved with the solution posted in [http://www.openstm32.org/tiki-view_forum_thread.php?comments_parentId=3096|-> Link fpv5-sp-d16
Floating-point ABI -> hard
Instruction Set -> Thumb II

I will be grateful for any help you can provide.

Hi,

I’ve had a similar error message. The problem was that the -mcpu=cortex-m7 option was missing in the compiler command (see Properties -> C/C++ Build -> Settings -> Tool Settings -> MCU GCC Compiler).

In Properties -> C/C++ Build -> Settings -> Target I’ve chosen: Series: STM32F7 and Mcu: STM32F746ZGTx (because the STM32F767ZIT is not supported by sw4stm32 V1.8 now). All target specific files (startup, ld, stm32f767xx.h) are for the STM32F767.

Then the build was successfully. It is a workaround, hope the F767 is supported by sw4stm32 soon.

I hope I could help you
