HAL Version Number Info

Question

Hello,

I've a question about the HAL-Version FW_L4_V1.15.1.

In the file stm32l4xx_hal.c there are defines for the HAL-Version-Number:

#define STM32L4XX_HAL_VERSION_MAIN (0x01U) /*!< [31:24] main version */

#define STM32L4XX_HAL_VERSION_SUB1 (0x0BU) /*!< [23:16] sub1 version */

#define STM32L4XX_HAL_VERSION_SUB2 (0x01U) /*!< [15:8] sub2 version */

#define STM32L4XX_HAL_VERSION_RC (0x00U) /*!< [7:0] release candidate */

I expected the Numbers (0x01U) (0x0FU) (0x01U) (0x00U)

Why the STM32L4XX_HAL_VERSION_SUB1 has a wrong value?

Best regards

I think it is due to the issue I have shared in my previous post.

As for the HAL version, it is actually the HAL L4 V1.12.0 driver version used in the STM32CubeL4 V1.16.0 firmware package, with the associated versions are the following:

You can refer to it in the Release_Notes.html file within the Cube MCU package.

Therefore, the HAL version V1.12.0 in the firmware package V1.16.0 is correct:

* @brief STM32L4xx HAL Driver version number
*/
#define STM32L4XX_HAL_VERSION_MAIN (0x01U) /*!< [31:24] main version */
#define STM32L4XX_HAL_VERSION_SUB1 (0x0CU) /*!< [23:16] sub1 version */
#define STM32L4XX_HAL_VERSION_SUB2 (0x00U) /*!< [15:8] sub2 version */
#define STM32L4XX_HAL_VERSION_RC (0x00U) /*!< [7:0] release candidate */
