STM32F4 micro-controllers come equipped with a built-in system bootloader capable of flashing over USB (via DFU), 3.3V Serial, and various other methods (see STM Document AN2606 for more information). Some STM32F4 boards, such as the SKR Pro 1.1, are not able to enter the DFU bootloader. The HID bootloader is available for STM32F405/407 based boards should the user prefer flashing over USB over using the sdcard. Note that you may need to configure and build a version specific to your board, a [build for the SKR Pro 1.1 is available here](https://github.com/Arksine/STM32_HID_Bootloader/releases/latest).
STM32F4 微控制器配备了一个内置系统引导加载程序，可通过 USB（通过 DFU）、3.3V 串行和其他各种方法（有关更多信息，请参见 STM 文档 AN2606）进行烧录。一些 STM32F4 板，例如 SKR Pro 1.1，无法进入 DFU 引导加载程序。针对基于 STM32F405/407 的板，提供了 HID 引导加载程序，用户可以选择通过 USB 进行烧录而不使用 sdcard。请注意，您可能需要配置和构建适用于您的板的特定版本，[此处提供了 SKR Pro 1.1 的构建版本](https://github.com/Arksine/STM32_HID_Bootloader/releases/latest)。
Unless your board is DFU capable the most accessible flashing method is likely via 3.3V serial, which follows the same procedure as [flashing the STM32F103 using stm32flash](#stm32f103-micro-controllers-blue-pill-devices). For example:
除非您的控制板支持 DFU，否则最易于访问的烧录方法可能是通过 3.3V 串口进行烧录，其遵循与 [使用 stm32flash 烧录 STM32F103](#stm32f103-micro-controllers-blue-pill-devices) 相同的过程。例如：
SAMDC21 micro-controllers (Duet3D Toolboard 1LC)
SAMDC21微控制器(Duet3D工具板1LC)
The SAMC21 is flashed via the ARM Serial Wire Debug (SWD) interface. This is commonly done with a dedicated SWD hardware dongle. Alternatively, one can use a [Raspberry Pi with OpenOCD](#running-openocd-on-the-raspberry-pi).
SAMC21通过ARM串行线调试(SWD)接口进行刷新。这通常是通过专用的社署硬件加密狗来完成的。或者，人们可以使用带有[Raspberry Pi的 OpenOCD](#running-openocd-on-the-raspberry-pi).
When using OpenOCD with the SAMC21, extra steps must be taken to first put the chip into Cold Plugging mode if the board makes use of the SWD pins for other purposes. If using OpenOCD on a Rasberry Pi, this can be done by running the following commands before invoking OpenOCD.
当将OpenOCD与SAMC21一起使用时，如果主板将SWD引脚用于其他目的，则必须采取额外步骤，首先将芯片置于冷插拔模式。如果在Rasberry PI上使用OpenOCD，可以通过在调用OpenOCD之前运行以下命令来完成。
