STM32CubeIDE Prebuild step does not work

[ola]

Hi All,

1. [Part Number] STM32WL33CC1
2. [Environment] Windows OS, STM32CubeIDE version 1.17.0, Firmware package STM32Cube FW_WL3 V1.0.0
3. [Schematics] STM32 Nucleo-64 development board
4. [Details] See below.
5. [Expected behavior] The script would patch file same baudrate
6. [How to reproduce] Write a script and add the script to the Prebuild step in Settings. 
7. [Occurrence] Consistent
8. [Sanity checks] See below.

Here’s a rephrased version of your text:

I am attempting to patch a file before building, but I have not been successful. I tried using both a .sh bash script and a Windows .bat file, and they work as expected when executed directly from their respective terminals.

However, when I run them through the STM32CubeIDE Pre-build step in the Settings, they fail to work as intended. Interestingly, the .bat file appears to execute and displays a message in the STM32CubeIDE console stating that the patch was applied. Yet, the actual file remains unchanged.

From git-bash I can run the following command from the root of the project

./stm32wl33x.sh

Below is the bash script that I tried running. This works fine when I use git-bash

#!/bin/bash
git apply stm32wl3x_hal_rcc_ex.patch
STRING="Patch applied successfully!"
echo $STRING

Below is the bat file that I tried running. Again this works fine under CMD.

@Echo off

REM Define the patch file path
set PATCH_FILE=C:\devl\WL33Devl\stm32wl3x_hal_rcc_ex.patch

REM Check if the patch file exists
if not exist "%PATCH_FILE%" (
    echo Error: Patch file "%PATCH_FILE%" not found!
    exit /b 1
)

REM Apply the patch
echo Applying patch from %PATCH_FILE%...
git apply "%PATCH_FILE%"
if errorlevel 1 (
    echo Error applying patch!
    exit /b 1
)

In the project setting I added the following to the Prebuild step as shown below

In STM32CubeIDE build output I get the following.

make -j20 all 
..\stm32wl33x.bat
Applying patch from C:\devl\WL33Devl\stm32wl3x_hal_rcc_ex.patch...
Patch applied successfully!

Even though it is showing that the patch has been applied successfully the stm32wl33x_hal_rcc_ex.c file is not modified by the patch.

Am I missing something? While I can work around this issue by running the patch from an external terminal, I would prefer to automate the patching process to avoid forgetting it.

Below is the content of the stm32wl3x_hal_rcc_ex.patch file:

diff --git a/Drivers/STM32WL3x_HAL_Driver/Src/stm32wl3x_hal_rcc_ex.c b/Drivers/STM32WL3x_HAL_Driver/Src/stm32wl3x_hal_rcc_ex.c

Many thanks in advance.
