STM32F746G-DISCO Unsupported

[pymaximus]

First of all, thanks for this project, it definitely helps my projects !!

Testing with a STM32 F7 Discovery board with STM32F746NGH6 MCU and cmake things its a 765xx device.

23:22 $ cmake -DSTM32_CHIP=STM32F746NG -DCMAKE_TOOLCHAIN_FILE=/Users/frank/other_repos/stm32-cmake/cmake/gcc_stm32.cmake -DCMAKE_BUILD_TYPE=Debug ../ -- No TARGET_TRIPLET specified, using default: arm-none-eabi -- No STM32_FAMILY specified, trying to get it from STM32_CHIP -- Selected STM32 family: F7 -- STM32F746NG is 765xx device

If I make the following change

diff --git a/cmake/gcc_stm32f7.cmake b/cmake/gcc_stm32f7.cmake index 910795c..0bfb256 100644 --- a/cmake/gcc_stm32f7.cmake +++ b/cmake/gcc_stm32f7.cmake @@ -5,7 +5,7 @@ SET(CMAKE_ASM_FLAGS "-mthumb -mcpu=cortex-m7 -mfpu=fpv5-sp-d16 -mfloat-abi=softf SET(CMAKE_EXE_LINKER_FLAGS "-Wl,--gc-sections -mthumb -mcpu=cortex-m7 -mfpu=fpv5-sp-d16 -mfloat-abi=softfp -mabi=aapcs" CACHE INTERNAL "executable linker flags") SET(CMAKE_MODULE_LINKER_FLAGS "-mthumb -mcpu=cortex-m7 -mfpu=fpv5-sp-d16 -mfloat-abi=softfp -mabi=aapcs" CACHE INTERNAL "module linker flags") SET(CMAKE_SHARED_LINKER_FLAGS "-mthumb -mcpu=cortex-m7 -mfpu=fpv5-sp-d16 -mfloat-abi=softfp -mabi=aapcs" CACHE INTERNAL "shared linker flags") -SET(STM32_CHIP_TYPES 745xx 765xx 756xx 767xx 777xx 769xx 779xx CACHE INTERNAL "stm32f4 chip types") +SET(STM32_CHIP_TYPES 745xx 746xx 756xx 767xx 777xx 769xx 779xx CACHE INTERNAL "stm32f4 chip types") SET(STM32_CODES "745.." "746.." "756.." "767.." "777.." "769.." "779..")

ie: change the 765xx into 746xx in STM32_CHIP_TYPES then all is well.

The flash and ram sizes are correct for this chipset, according to the linker script provided by STM32Cube

Thanks for reporting!
