Hello, i am trying to use system bootloader in STM32F411 for software update via USB. I use a freertos in my project.
Workflow is here: By sending a "BOOT" via Virtual Com Port USB, MCU executes folowing code:
Spoiler
USBD_Stop(&hUsbDeviceFS);
uint32_t i=0;
void (*SysMemBootJump)(void);
/* Set a vector addressed with STM32 Microcontrollers names */
/* Each vector position contains an address to the boot loader entry point */
volatile uint32_t BootAddr[33];
BootAddr[C0] = 0x1FFF0000;
BootAddr[F030x8] = 0x1FFFEC00;
BootAddr[F030xC] = 0x1FFFD800;
BootAddr[F03xx] = 0x1FFFEC00;
BootAddr[F05] = 0x1FFFEC00;
BootAddr[F07] = 0x1FFFC800;
BootAddr[F09] = 0x1FFFD800;
BootAddr[F10xx] = 0x1FFFF000;
BootAddr[F105] = 0x1FFFB000;
BootAddr[F107] = 0x1FFFB000;
BootAddr[F10XL] = 0x1FFFE000;
BootAddr[F2] = 0x1FFF0000;
BootAddr[F3] = 0x1FFFD800;
BootAddr[F4] = 0x1FFF0000;
BootAddr[F7] = 0x1FF00000;
BootAddr[G0] = 0x1FFF0000;
BootAddr[G4] = 0x1FFF0000;
BootAddr[H503] = 0x0BF87000;
BootAddr[H563] = 0x0BF97000;
BootAddr[H573] = 0x0BF97000;
BootAddr[H7x] = 0x1FF09800;
BootAddr[H7A] = 0x1FF0A800;
BootAddr[H7B] = 0x1FF0A000;
BootAddr[L0] = 0x1FF00000;
BootAddr[L1] = 0x1FF00000;
BootAddr[L4] = 0x1FFF0000;
BootAddr[L5] = 0x0BF90000;
BootAddr[WBA] = 0x0BF88000;
BootAddr[WBX] = 0x1FFF0000;
BootAddr[WL] = 0x1FFF0000;
BootAddr[U5] = 0x0BF90000;
/* Disable all interrupts */
__disable_irq();
/* Disable Systick timer */
SysTick->CTRL = 0;
/* Set the clock to the default state */
HAL_RCC_DeInit();
/* Clear Interrupt Enable Register & Interrupt Pending Register */
for (i=0;i<5;i++)
{
NVIC->ICER[i]=0xFFFFFFFF;
NVIC->ICPR[i]=0xFFFFFFFF;
}
SYSCFG->MEMRMP = 0x01;
/* Re-enable all interrupts */
__enable_irq();
/* Set up the jump to boot loader address + 4 */
SysMemBootJump = (void (*)(void)) (*((uint32_t *) ((BootAddr[MCU] + 4))));
/* Set the main stack pointer to the boot loader stack */
__set_MSP(*(uint32_t *)BootAddr[MCU]);
/* Call the function to jump to boot loader location */
SysMemBootJump();
/* Jump is done successfully */
while (1)
{
/* Code should never reach this loop */
}
and succesfully jumps into embedded bootloader, so I can read an mcu software with usb in dfu mode
but I can't update a software using "Erasing and programming" tab and get errors "LIBUSB_NO_DEVICE" after erasing of previous software

What should i fix in my code to flash a new .hex properly ? Thank you in advance
