Can't jump to STM bootloader on STM32L051

I have tried to jump to STM bootloader, but unfortunately STM reset after that. Where can be error?

SysMemBootJump = (

void

(*)(

void

)) (*((

unsigned

int

*) 0x1FF00000 + 4));

__disable_irq(); HAL_RCC_DeInit(); SysTick->

CTRL

= 0; SysTick->

LOAD

= 0; SysTick->

VAL

= 0;

__set_MSP

(*(__IO

uint32_t

*) 0x1FF00000);

SysMemBootJump

();

This code works fine on STM32L151 and STM32F401(with appropriate addresses).

Can you tell me what type STM32L051 you are using?

What is your clock source and speed? How do you want to use the bootloader usb, can, uart?

I use STM32L051C6T6. I have tried HSI(16 MHz) without PLL and MSI (4.2 MHz) both with same result. In my plan, download firmware through USART1 (PA9, PA10)

Where can be error? With the Cortex-M0 you're definitely going to need to map the ROM at zero before you start. These are for the F0 series, you'll need to do something chip appropriate for the L0
