STM32F105 problem jumping to application

I have problem with jump to application by bootloader.

The device used is the STM32F105R8. The bootloader does not jump in the application,it crashes in the function ''Jump_To_Application()''. The code of the bootloader making the jump is: #define APPLICATIONADDRESS    (uint32_t)0x08008000 /* Test if user code is programmed starting from address ''ApplicationAddress'' */ if (((*(__IO uint32_t*)APPLICATIONADDRESS) & 0x2FFE0000 ) == 0x20000000)     {                             /* Jump to user application */         JumpAddress = *(__IO uint32_t*) (APPLICATIONADDRESS + 4);         Jump_To_Application = (pFunction) JumpAddress;         /* Initialize user application's Stack Pointer */         __set_MSP(*(__IO uint32_t*) APPLICATIONADDRESS);         Jump_To_Application();     } In the application i have relocate the vector table: int main(void) {     //    __disable_irq();              /* Set the Vector Table base location at 0x8000 */       NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x8000);     //    __enable_irq();       /***************** Add your application code here   ***************************/     ........ } I attached the image (bootloader + application) downloaded  from flash.

Awesome, I hope this all works out for you, but the presented facts appear internally inconsistent.

Look the ''stsw-stm32121_USB\STM32_USB-FS-Device_Lib_V4.0.0\Projects\Device_Firmware_Upgrade\binary_template'' use same method.

Bootloader ==> 0x08000000 to 0x08003000 Application ==> 0x08003000 to 0x08020000 In the main function set the Vector Table base location at 0x3000: NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x3000);  The option target for application is:

So 0x7000 when it's 0x8000 is consistent with this? 64K-0x8000 = 0x9000! And the binary generated with a ResetHandler at ~0x08007000 when the linker is set at 0x08008000

I agree with

you!

This is the only

method

that works!

I asked

clarifications

the

ST

support

,

but

do not respond

!

I've got quite a lot of mileage on these types of solutions (boot loader + app, STM32), if it misbehaves in the manner you describe the problem is most likely in the project (options/metadata), the files it actually uses (paths, defines, pre-processor), and the tool chain (linker).

Keil support might be a better avenue. For ST you'd probably want to go via your local distributor and their FAE's, and have them thoroughly replicate and understand your issue.
