Where are the original files when generating with SoftwarePackage BLE2?

[ANauz.1]

Hello,

I'm using CubeMX with X-CUBE-BLE2 3.1.0 Software Package to generate the SampleApplication

I am generating for my L073RZ-NucleoBoard.

The code generated work, but each time I generate, I have to make modification in the generated file Drivers/BSP/STM32L0xx_nucleo.c

So I would like to make the modification in the original file, but I could not find it:

• STM32Cube_FW_L0_V1.12.0/Drivers/BSP/STM32L0XXNucleo is not the same file
• In X-CUBE-BLE2\3.1.0\Drivers\BSP there is only a L4XX file
• Same in X-CUBE-BLE2\3.1.0\Projects\STM32L476RG-Nucleo\Applications\SampleApp\Src

So, either I am missing the correct location, or maybe MX is using a template, but where is it to modify it to generate the file with my modification

Thank you for your help

On example of my "problem"

When generating, in the file Drivers/BSP/STM32L0xx_Nucleo/STM32L0xx_nucleo.c, the function:

static void BUTTON_USER_GPIO_Init(void)

is empty. And I could not find any file in repository (neither FW_L0_V1.12.0, X-CUBE-BLE2 or any other) with this function empty.

What I do not understand is that, on the other hand, in the same file, the function:

static void BUTTON_USER_EXTI_Callback(void)

is not empty.

So which is the definition of BUTTON_USER_GPIO_Init that is used and inserted in my project?

Thanks

Ok....

I removed the repository directory of the BLE Package.

I removed the repository directory of the L0 MCU.

...And MX is still capable of generating the files. It must use a file that is in another directory! But I could not figured out which one!

Does anybody have an idea?

Thank you

Antoine

Hi @ANauz.1​ ,

Sorry for the delay.

Indeed STM32CubeMX use a template file to generate the STM32L0xx_nucleo.c.

You can find it under CubeMX install folder: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\db\templates\bsp\bsp_common_c_BZ64601_79509.ftl .

Please be careful when modifying template files to avoid possible problems .
