something goes wrong when i want to run micropython on my own stm32 board
port-stm32
Hi !
For some reason, I can't use pyboard in my application. I need to make my own stm32 board to run micropython.
Now I'm trying to download the firmware to my board. The board I use has a STM32F407VGT6, same as STM32F4DISC.
So I try to download STM32F4DISC-20200328-v1.12-310-g9418611c8.dfu to the board with DfuSeDemo :
- set BOOT0 = 1, BOOT1 = 0
- power on
- download the dfu file with DfuSeDemo
- power off after download
- set BOOT0 = 0, BOOT1 = 0
but nothing happens when I power on. i did't see a new USB flash drive on my PC.
So what can i do? is there a guide to follow if i want to run micropython on my own board?
