Hello there! I’m new to a PlatformIO and recently i bought DevEBox H743VITX with STM32H743VIT6 on it. Also i found a documentation about board, i don’t understand how i put this board in other than DFU mode when i’m connection 3v3 and BTO Pins. How can i put this board in “Normal” mode so i can upload my code from main.cpp like with other microcontrollers? Thank you vm.
When BOOT0 (BT0) pin is HIGH (“1”, 3.3.V), and BOOT1 is 0, then the device will boot from “system memory”, which means DFU bootloader.
When BOOT0 pin is LOW (“0”, GND), it will the firmware you uploaded.
Hello! Thank you for your reply. Yes i know about the BTO Pin, thank you! The problem is, when i upload the code in VS Code with PlatformIo with connected BTO to 3v3, it uploads but shows the problem in the end: "File downloaded successfully
Submitting leave request…
dfu-util: Error during download get_status
*** [upload] Error 74 "
What can cause that problem?
Code from platformio.ini -
[env:devebox_h743vitx]
platform = ststm32
board = devebox_h743vitx
framework = arduino
upload_protocol = dfu
Also wanted to ask, if it possible to use serial monitor w/o the extern programmer (like ST-LInk and etc)? Thank you for your reply!
