How to change makefile in stm32F429.

[zhuantou215]

Thank you very much for helping me before. Since I was a novice, I downloaded the official STM32F746G-Discovery Template, and I want to change the makefile to generate a binary executable for STM32F429. So I changed the makefile to:

    OPT_OS                    = raw32
    OPT_THUMB                = yes
    OPT_LINK_OPTIMIZE        = no
    OPT_CPU                    = stm32m4

# uGFX settings
    # See $(GFXLIB)/tools/gmake_scripts/library_ugfx.mk for the list of variables
    GFXLIB                    = ../uGFX
    GFXBOARD                = STM32F429i-Discovery
    GFXDEMO                    =
    GFXDRIVERS                =
    GFXSINGLEMAKE            = no

# Special - Required for the drivers for this discovery board.
STMHAL                        = ../STM32F4xx_HAL_Driver

# Special - Required for Raw32
CMSIS                        = ../CMSIS

Whenever you run make. There is always an error .. ../uGFX/src/gos/gos_rules.h:24:3: error: #error "GOS: More than one operation system has been defined as TRUE."
 #error "GOS: More than one operation system has been defined as TRUE .. So I hope you can help me.

The error message is very clear: The underlying system has been defined more than once. This usually happens if you set your underlying operating system both in your configuration file (gfxconf.h) as well as your makefile. Just remove the declaration from your configuration file.

Thank you very much. If I wanted to change STM32F746 to STM32F429, could you give me a template? For example stm32f429_discovery_sdram.c,stm32f7_i2c.c,and so on.

There are two ready-to-run demo projects for the STM32F429i-Discovery board available: https://community.ugfx.io/files/category/2-example-projects/
However, they are both ChibiOS based.

We don't have anything other than those projects. There are just way too many different configurations (IDEs, underlying systems, HALs, ...) that we could provide everything.
When working with the CubeHAL I'd recommend you to have a look at the examples that ST provides. They tend to be quite verbose.
