WeAct HID bootloader

Important note

If there is no WeAct and version number on the back of the board, the chip batch is 537 or old, the stitches and board are packaged in one bag, the board screen printing is wrong(3V3 is going to be labeled V3V), it is definitely pirated.Please comment on issues or let us know by email (WeAct_TC@163.com).

This software refers to the following source code, but it is not modified from the following source code STM32_HID_bootloader https://github.com/Serasidis/STM32_HID_Bootloader.git

Both STM32F401CC and STM32F411CE core boards can be used If the HID device appears when the core board is connected to the computer via USB, the bootloader has been programmed and can be downloaded directly without serial port, STLink, or J-link.

Core board There is no HID device when USB is connected to the computer, there is no bootloader,.Please flash the bootloader to 0x8000000

The APP program can be debugged by the debugger without any impact.

Enter the bootloader method

  1. Hold down the <KEY key>, power on or reset again, and the C13 LED will blink to release
  2. APP enters the bootloader reference stm32f401_test_APP 0x8004000.zip project

In the bootloader:

  1. <KEY key> Click to turn on or off the C13 LED
  2. The SW debug port is open and can be programmed by the debugger without entering DFU mode
  3. Long press the <KEY key>, the C13 LED flashes and you can release it，MCU will enter Embedded bootloader

Exit the bootloader method

  1. Reset MCU, reset key / upper computer click <MCU reset>
  2. Long press the <KEY key>, the C13 LED flashes and you can release it

HID bootloader V1.1

  1. Fix Bugs,
  2. Long press the <KEY key>, MCU will enter Embedded bootloader,ISP Mode
  3. Remove double-click function
  4. Reduce the size of bootloader firmware

HID bootloader V1.2

  1. Fixed a problem with systick not closing

Note: Bootloader and APP programming software are not open source
