template file system_stm32f4xx.c should support userdefined location of vectortable about stm32cubef4

[theadib]

please ST
the register holding the vector address should be written as part of the startup code in any case.
not only when USER_ADDRESS is defined.

SCB->VTOR = VECT_TAB_BASE_ADDRESS | VECT_TAB_OFFSET;

Hi @theadib,

Thank you for your contribution. Our development teams confirmed the issue you pointed out. The fix below will be available in the next release.

+ #if defined(USER_VECT_TAB_ADDRESS)
/* #define VECT_TAB_SRAM */
+ #if defined(VECT_TAB_SRAM)
+ #define VECT_TAB_BASE_ADDRESS   SRAM_BASE       /*!< Vector Table base address field.
+                                                    This value must be a multiple of 0x200. */
+ #define VECT_TAB_OFFSET         0x00000000U     /*!< Vector Table base offset field.
+                                                    This value must be a multiple of 0x200. */
+ #else
+ #define VECT_TAB_BASE_ADDRESS   FLASH_BASE      /*!< Vector Table base address field.
+                                                     This value must be a multiple of 0x200. */
+ #define VECT_TAB_OFFSET         0x00000000U     /*!< Vector Table base offset field.
+                                                    This value must be a multiple of 0x200. */
+ #endif /* VECT_TAB_SRAM */
+ #endif /* USER_VECT_TAB_ADDRESS */

I hope this answer helps. If you have no other question about this subject, I think this issue can be closed.

Hi @RKOUSTM

In STM32duino, it is possible to redefine VECT_TAB_OFFSET to use a bootloader.
In a general way Bootloader is stored at the beginning of the FLASH, in that case the VECT_TAB_OFFSET is set to the SCB->VTOR = FLASH_BASE | VECT_TAB_OFFSET; where offset is set after the BL.

With the USER_VECT_TAB_ADDRESS I don't understand how we can properly set it as the VECT_TAB_OFFSET is always 0.
This only allow to set it to SRAM or FLASH.

Hi @fpistm,

Thank you for your contribution. The above fix is proposed to mention if we are on FLASH or SRAM, and if we want to apply a different Offset value, as in the STM32WL, the following:

/* #define VECT_TAB_SRAM */
#if defined(VECT_TAB_SRAM)
#define VECT_TAB_BASE_ADDRESS   SRAM2_BASE      /*!< Vector Table base address field.
                                                     This value must be a multiple of 0x100. */
#define VECT_TAB_OFFSET         0x00008000U     /*!< Vector Table base offset field.
                                                     This value must be a multiple of 0x100. */
#else
#define VECT_TAB_BASE_ADDRESS   FLASH_BASE      /*!< Vector Table base address field.
                                                     This value must be a multiple of 0x100. */
#define VECT_TAB_OFFSET         0x00020000U        /*!< Vector Table base offset field.
                                                     This value must be a multiple of 0x100. */
#endif

Thank you again for your contribution.

Thanks for the feedback @RKOUSTM
But I think the OP request concern the VECT_TAB_OFFSET not if we are on FLASH or SRAM.
Anyway you answered my question and will update STM32duino to also be able to redefine VECT_TAB_OFFSET

Hi @theadib,

I hope you are fine. The issue you reported has been fixed in the frame of version v1.26.0 of the STM32CubeF4 published recently on GitHub.

Thank you again for having reported.
