systick is not working after jump.

[Rkuma.1964]

below are the codes(0x0801E000U) which is used for jump:

#define PROJ1_FLASHADDR 0x08000000U

#define PROJ2_FLASHADDR 0x0801E000U

 __disable_irq();

 /* Get the main application start address */

 uint32_t jump_address = *(__IO uint32_t *)(PROJ1_FLASHADDR + 4);

 /* Set the main stack pointer to to the application start address */

 __set_MSP(*(__IO uint32_t *)PROJ1_FLASHADDR);

 /* Create function pointer for the main application*/

 void (*pmain_app)(void) = (void (*)(void))(jump_address);

 /* Now jump to the main application*/

 pmain_app();

i am also enabling irq in the beginning of main function.

Seems like a statement of facts rather than a question.

Make sure SCB​->VTOR points to the vector table properly

[Rkuma.1964]

SCB->VTOR is points to correct vector table. i checked it.

i think my systick is not working properly after jump.

any suggestion will be very helpful.

find your systick interrupt vector entry address in your new vector table. check that​ there is correct code in that address.

also capture systick registers before jump and compare with the values after jump

Are you performing the jump within an interrupt?

[Rkuma.1964]

Hi TDK,

i am not performing jump in an ISR.

jump performing in a task of freertos.

>>jump performing in a task of freertos.

You'd likely want to do it from a system state.

Consider if you can generate a reset, and then transfer control immediately in Reset_Handler.

[Rkuma.1964]

for my project jump is required not reset.

how i can switch to system state from a task?

Do you enable interrupts after jumping?

[Rkuma.1964]

yes,

right after entering the main function.

[Piranha]

Your code jumps to PROJ1_FLASHADDR - most likely itself...

[Rkuma.1964]

yes it should jump to itself but it is getting stuck at systeminit.

Pretty sure the issue is that while one task is jumping to another spot, the rest of your system is still in its previous state.
