Problem after jump from bootloader to RTOS application (Freertos) with call osKernelStart();
Hello,
I have problem after jump from bootloader to FreeRTOS application
I use STM32F09 (HAL) chip.
Jump from bootloader to Freertos application => OK
But when I call "osKernelStart()" board crashed
In debug I crashed in function
xPortStartScheduler()
---------------------
This is my code to jump to FreertosApplication
__entry_point = 0x0801A191
void startFirmwareApplication(void)
{
/// BOOT START APPLICATION (i.e execute SP310 FIRMWARE entry point)
MSG(" mainTask *** BOOT START APPLICATION \n");
vTaskSuspendAll();
taskDISABLE_INTERRUPTS();
__disable_irq();
__HAL_RCC_GPIOE_CLK_ENABLE();
//__HAL_RCC_GPIOB_CLK_ENABLE(); //@TODO
GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
GPIO_InitStruct.Pin = GPIO_PIN_7;
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
GPIO_InitStruct.Pin = GPIO_PIN_0;
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
GPIO_InitStruct.Pin = GPIO_PIN_8;
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
// GPIO_InitStruct.Pin = GPIO_PIN_1; //@TODO
// HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

HAL_RCC_DeInit();
/* Disable all interrupts */

/* Clear all interrupt priority */
for (int tmp = 0; tmp < 7; tmp++) {
NVIC->IP[tmp] = 0x00;
}
auto address = reinterpret_cast<uint32_t>(__entry_point);
/* change control register */
__set_CONTROL(0);

}This is my code in Freertos appliction to remap vector table

void Remap_Table(void)
{
uint32_t i = 0;
for(i = 0; i < 48; i++)
{
VectorTable[i] = *(__IO uint32_t*)(FIRMWARE_START_ADDR + (i<<2));
}

// Enable the SYSCFG peripheral clock

can you help me please ?
