Posted on March 21, 2018 at 07:36I am using STM32L073RZ . I want to use UART as a bootloader .Please provide me the code which invoke internal bootloader so that I can flash the micro using flasherdemo.exe (a tool provided by ST).Thanks for help.
Here is a sample code that I have writed but not working.
&sharpdefine SYSMEM_ADDRESS (uint32_t)0x1FFF0000
void Bootloader_JumpToSysMem(void)
{
uint32_t JumpAddress = *(__IO uint32_t*)(SYSMEM_ADDRESS + 4);
pFunction Jump = (pFunction)JumpAddress;
HAL_NVIC_DisableIRQ(USARTX_IRQn);
HAL_UART_DeInit(&UartHandle);
HAL_RCC_DeInit();
HAL_DeInit();
SysTick->CTRL = 0;
SysTick->LOAD = 0;
SysTick->VAL = 0;
__HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH();
__set_MSP(*(__IO uint32_t*)SYSMEM_ADDRESS);
Jump();
// HAL_GPIO_TogglePin(LED2_GPIO_PORT, LED2_PIN);
while(1);
}
#stm32l073rz #flasherdemo #bootloader #internal_bootloader
