The STM32 Flash loader demonstrator (FLASHER-STM32) is a free software PC utility from STMicroelectronics, which runs on Microsoft ® OSs and communicates through the RS232 with the STM32 system memory bootloader. To get an example of how to execute the device bootloader, refer to the STM32 microcontroller system memory boot mode Application. Dec 30, 2018  The bootloader was developed for STM32VLDISCOVERY board, the only extra thing needed is an USB-UART module on PA10 (RX) and PA9 (TX) pins. Pinout of the system. After start-up, the system sends a welcome message through UART and checks if the user button is pressed. If it is pressed, then. Now the “STM32 BOOTLOADER” entry appears under “Other devices”. Its icon is labelled with a warning that no matching driver could be found by the Windows system: Now the new driver can be installed: Unpack the “RadioShuttle STM32 Tools.zip” archive; Double-click the “STM32 BOOTLOADER” entry to open its properties. STM32 Bootloader. This post is all about installing STM32 Bootloader, i.e Programming STM32F103C8 Board using micro USB Port directly via Arduino IDE. STM32 Development Board or STM32F103C8 Microcontroller can be easily programmed using the Arduino IDE, only after installing bootloader. Latest download for STM32 BOOTLOADER driver. Improve your pc peformance with this new update. Any of these methods are great if they get the job done. In this topic, let us focus on how to perform STM32 flashing by using a bootloader. Today probably, no manufacturer is producing developing boards with RS232 interface.

Hi,

Thanks for the reply.

I suggest you to follow the steps below and check if it helps.

Method 1: Run Hardware Troubleshooter to diagnose issue with hardware if there are any on your computer. Follow the steps:

1. Click on Start icon or hit Windows logo and click on Settings.
2. Type Troubleshooting and select troubleshooting.
3. Click on Hardware and Sound and select Hardware and Devices and click on next and follow the on-screen instructions.

Method 2: Disable and re-enable all the Universal Serial Bus controllers (USB) controllers.

The USB controllers represent the USB ports in Device Manager.

To disable and re-enable the USB controllers, follow these steps:

a) Open Device Manager.

b) Expand Universal Serial Bus controllers.

c) Note: You might have to scroll down the list to find this item.

d) Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.

e) Repeat the above step for each USB controller that is listed under Universal Serial Bus controllers.

f) Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and

g) Reinstall all the USB controllers that you uninstalled.

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

I have a requirement for firmware upgrade. I am planning to use USB DFU class. But command for firmware upgrade will come from PC application in my case . so i need to switch to bootloader which is there in System Memory. As initially i am running application so it is getting booted from User flash i.e i have Boot0 and Boot 1 pins configured for User flash. As DFU bootloader is there in System flash ,now for that Boot0 and Boot1 pins settings need to be changed . is there a way like Boot 0 and Boot 1 settings remain same as User Flash memory and in the application we jump to System Memory?

Boot0/1 pins are sampled only when the processor starts, in order to check if it should load the user code from memory or if it should load the bootloader.The state of these pins has no effect of the bootloader afterwards.

I've been faced to a similar request, and found 2 ways to load the bootloader on-demand.

First, you can 'JUMP' from user-code to the bootloader. For example, you could jump to the bootloader when a button is pressed.

But.. this is far more complicated than a simple JUMP instruction : some registers and devices must be reconfigured correctly to work with the bootloader, you have to ensure that no IRQ will be triggered during the JUMP,.. In fact, you have to reconfigure the processor as if it was just started after reset.You can find some information about this technic : on this video from ST.

I managed to do this kind of things on STM32F1xx project.However, on a more complex project based on STM32F4, this would become really difficult.. I would have to stop all devices (timers, communication interface, ADC, DAC,..), ensure that no IRQ would be triggered, reconfigure all the clocks,..

Instead, I decided to implement this second solution: When I want to jump to the bootloader, I write a byte in one of the backup register and then issue a soft-reset. Then, when the processor will restart, at the very beginning of the program, it will read this register. This register contains the value indicating that it should reboot in bootloader mode. Then, the jump to the bootloader is much easier, as presented in the youtube video.

In MicroPython there is a pyb.bootloader() function which is used to enter into DFU mode.

The C code which implements that can be found in their source repository.

I've used the STM32F4 version extensively (the #else block), and the F7 variant a few times (although its been a while).

I'll put the body of the function here since the above links could become stale if that file changes:

The pyb_usb_dev_deinit() function shuts down USB, and storage_flush writes out any cached filesystem data. The HAL functions come from the STM32Cube HAL files.

If you use a newer version of dfu-util (IIRC 0.8 or newer) then you can specify the -s :leave command line option to have your newly flashed program executed at the end of flashing. Combining with the above I go through flash/test cycles without having to touch the board, and only use BOOT0/RESET when the firmware hard-crashes.

There is also a python DFU flasher called pydfu.py: https://github.com/micropython/micropython/blob/master/tools/pydfu.py which is a little faster than dfu-util.

To jump to a new image is not that difficult. I have done it successfully as part of a power on self test.

1. You have to pass the address of where your second image (the bootloader in this case) resides in flash to the linker when you link the second image. You could possibly use position independent code instead, but that has other issues.
2. You have to, obviously, flash program the second image starting from the same address as you gave the linker.
3. Set the jump function: void (* const jumpFunction)(void) = (void (*)(void))(APPLICATION_ADDRESS + 4ul + 1ul); The offset by four is to get past the stack pointer, the offset by one is for Thumbmode.
4. Specify the new stack starting pointer: __set_MSP((uint32_t)*APPLICATION_ADDRESS), the first four bytes from the second image will contain the new stack pointer.
5. Jump by calling the function: jumpFunction();
6. In the second program, the default initialisation will try and set the vector table offset (VTOR) SCB->VTOR = FLASH_BASE VECT_TAB_OFFSET;. You have to change this to SCB->VTOR = APPLICATION_ADDRESS VECT_TAB_OFFSET;

I have a POST program at FLASH_BASE that uses the core coupled SRAM for the its stack and then runs memory checks on the main SRAM, checks the authenticity of the main program and then jumps to the main program.

I can still debug the main program as if nothing changed.

NB! I have only recently done this myself. There are a few things I need to verify. One concern is what would happen with a software reset. If called from the second program it will go, I think, to the reset routine of the second program, not the first.

Freehand software for windows. You can simulate the bootloader condition. Connect capacitor and paralel resistor from BOOT pin to ground. Connect another free pin to BOOT pin. Capacitor can be charged by external pin and is discharged by resistor. I don't remember exact values you can calculate/experiment them (important is time constant of RC circuit).

Charge this capatitor by setting external pin to 1, perform software reset by NVIC_SystemReset. After reset, it will run bootloader. Resistor connected to Capacitor will perform discharging. After firmware update, you can reset the device and it will run to your application.

We are using this in some applications and it works well. Drawback of this solution is that you need external circuitry, but it is very easy to implement and it is universal for all STM32 devices.
