SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32


"expected identifier before '(' token" error during build

I am building a project which is a slightly modified version of BLE_Sample_App provided by ST. Before my last modifications, the IDE was succesfully building it. However, when I added some new functionality to the main code and added a couple of new source&header files, the IDE started complaining about line104 of stm32l4xx_hal_gpio.h, which is the definition of GPIO_PIN_2. The corresponding code part is below:

/* Exported constants --------------------*/
/** @defgroup GPIO_Exported_Constants GPIO Exported Constants
* @{
*/
/** @defgroup GPIO_pins GPIO pins
* @{
*/

  1. define GPIO_PIN_0 ((uint16_t)0x0001) /* Pin 0 selected */
  2. define GPIO_PIN_1 ((uint16_t)0x0002) /* Pin 1 selected */
  3. define GPIO_PIN_2 ((uint16_t)0x0004) /* Pin 2 selected */
  4. define GPIO_PIN_3 ((uint16_t)0x0008) /* Pin 3 selected */
  5. define GPIO_PIN_4 ((uint16_t)0x0010) /* Pin 4 selected */
  6. define GPIO_PIN_5 ((uint16_t)0x0020) /* Pin 5 selected */
  7. define GPIO_PIN_6 ((uint16_t)0x0040) /* Pin 6 selected */
  8. define GPIO_PIN_7 ((uint16_t)0x0080) /* Pin 7 selected */
  9. define GPIO_PIN_8 ((uint16_t)0x0100) /* Pin 8 selected */
  10. define GPIO_PIN_9 ((uint16_t)0x0200) /* Pin 9 selected */
  11. define GPIO_PIN_10 ((uint16_t)0x0400) /* Pin 10 selected */
  12. define GPIO_PIN_11 ((uint16_t)0x0800) /* Pin 11 selected */
  13. define GPIO_PIN_12 ((uint16_t)0x1000) /* Pin 12 selected */
  14. define GPIO_PIN_13 ((uint16_t)0x2000) /* Pin 13 selected */
  15. define GPIO_PIN_14 ((uint16_t)0x4000) /* Pin 14 selected */
  16. define GPIO_PIN_15 ((uint16_t)0x8000) /* Pin 15 selected */
  17. define GPIO_PIN_All ((uint16_t)0xFFFF) /* All pins selected */

  1. define GPIO_PIN_MASK ((uint32_t)0x0000FFFF) /* PIN mask for assert test */


What I don’t get is, why it is giving an error only for GPIO_PIN_2? I checked the other places this definition is used, but in those two other places, the new definitions are also legit. Finally, below is the console output when I try to build my project:

It would be great if anyone could help me with this.
