Small presentation about ways of using system memory boot loader on STM32

2. Default Bootloader
STM32 microcontroller system memory boot mode

3. PIC16F877 ATMEGA32

4. PIC16F877 ATMEGA32 Arduino

5. AVR ISP / SPI

6. SWD?
JTAG?

8. FLASH
BOOT ROM
ALIASED

13. Если есть дефолтовый бутлоадер
— зачем писать свой?
USECASES

14. A)
Да, можно прошить свой бутлоадер
программатором, и его юзать.

15. B)

16. C)

21. DFU(se) File:

22. dfuse-tool
$ ./dfu-convert -i ~/…/Debug/
d4_blinker.hex d4_bl1.dfu
$ dfu-util -l
$ dfu-util -a 0 -d 0483:df11
-D d4_bl1.dfu

23. dfuse-tool
$ dfu-util -a 0 -d 0483:df11
-D d4_bl1.dfu
STMicroelectronics USB VID
“DFU”
Alt.set. ?
0 - for main flash

24. 1) arm-none-eabi-objcopy -O binary "${BuildArtifactFileBaseName}.elf" "${BuildArtifactFileBaseName}.bin"
2) && arm-none-eabi-objcopy -O ihex "${BuildArtifactFileBaseName}.elf" "${BuildArtifactFileBaseName}.hex"
3) && arm-none-eabi-size "${BuildArtifactFileName}"
arm-none-eabi-objcopy -O ihex

26. STM32 Flash loader
demonstrator (UM0462)

27. stm32loader
$ ./stm32loader.py -e -w -v -p /dev/ttyUSB0 bluepill.bin
Bootloader version 22
Chip id: 0x410 (STM32 Medium-density)
Write 256 bytes at 0x8000000

28. stm32loader
$ ./stm32loader.py -e -w -v -p /dev/ttyUSB0 bluepill.bin
