Hi everyone,
I use a JumpToBootloader( ) function in my code to execute system memory bootloader. and then STM32CubeProgrammer connect ok, but it can not program
MCU:STM32G030K6T6 STM32CubeProgrammer: v2.4.0
Boot Interface: UART1 (PA9 PA10)+MAX13487EESE(RS485 witch AutoDirection Control)
here is JumpToBootloader(void)
static void JumpToBootloader( void )
{
uint32_t i = 0;
void ( *SysMemBootJump )( void ); /*declare a function pointer 声明一个函数指针 */
__IO uint32_t BootAddr = 0x1FFF0000; /* BootLoader address*/
/*Turn off global interrupts 关闭全局中断 */
__disable_irq();
/* Turn off the tick timer, reset to default 关闭滴答定时器，�?�?到默认值 */
SysTick->CTRL = 0;
SysTick->LOAD = 0;
SysTick->VAL = 0;
/* Set all clocks to default state, use HSI clock 设置所有时钟到默认状�?，使用HSI时钟 */
HAL_RCC_DeInit();
/* Disable all interrupts, clear all interrupt pending flags 关闭所有中断，清除所有中断挂起标志 */
for ( i = 0; i < 1; i++ )
{
NVIC->ICER[i] = 0xFFFFFFFF;
NVIC->ICPR[i] = 0xFFFFFFFF;
}
/* Enable global interrupt 使能全局中断 */
__enable_irq();
/* Jump to the system BootLoader 跳转到系统BootLoader，首地�?�是MSP，地�?�+4是�?�?中断�?务程�?地�?� */
SysMemBootJump = ( void ( * )( void ) ) ( *( ( uint32_t * ) ( BootAddr + 4 ) ) );
/* set the main stack pointer 设置主堆栈指针 */
__set_MSP( *( uint32_t * )BootAddr );
/* Jump to the system BootLoader 跳转到系统BootLoader */
SysMemBootJump();
/* */
while ( 1 )
{
}
}
there is STM32CubeProgrammer log:
