Jump Application Code And Eeprom Fault

[DCtech]

I am trying to jump user application from boot code:

Boot code only include below lines:

  

HAL_Init();
 SystemClock_Config();
 // Jump proccess start
 uint32_t reset_handler_add=*((volatile uint32_t*)(FLASH_APP_START_ADDRESS+4));
 void (*app_reset_handler)(void) = (void*)reset_handler_add;
HAL_RCC_DeInit(); 
 HAL_DeInit();
 __HAL_RCC_SYSCFG_CLK_DISABLE(); 
 SysTick->CTRL = 0; 
 SysTick->LOAD = 0; 
 SysTick->VAL = 0; 
 __disable_irq(); 
 SCB->VTOR = FLASH_APP_START_ADDRESS; 
 uint32_t msp_value = *((volatile uint32_t*)(FLASH_APP_START_ADDRESS));
 __set_MSP(msp_value);
 app_reset_handler();

Also #define FLASH_APP_START_ADDRESS 0x080A0000 this is application code start address.

But when I jump the User application I2C and DMA not working so, I couldnt use eeprom

In the User application I stuck in while (HAL_I2C_GetState(hi2c) != HAL_I2C_STATE_READY) function when I jump the User App. But If User App work on the base 0x080000000 address everything successfull, When I jump I have problem.

I changed flash.Ld file:

MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 192K
CCMRAM (rw) : ORIGIN = 0x10000000, LENGTH = 64K
FLASH (rx) : ORIGIN = 0x080A0000, LENGTH = 256K
}

And changed #define VECT_TAB_OFFSET 0xA0000 value.

Where is the faults ?

I'd imagine disabling IRQs has some down stream consequences if you expect those to be working..

1. I remove this line __disable_irq(); I get same error again.
