I am trying to upload Ardupilot to my board. The co-processor works just fine with the regular procudure but no matter how much I tried, could not get the firmware on MCU.
I have tried with the regular upload process documented on LINK . However, even Windows 11 and ubuntu 22.04 do not seem to recognize the device. The output of lsusb shows no sign of a device while windows does not have any idea of its existence.
The board features STM32H75 as its MCU and STM32F301 as co-processor.
Solved! Go to Solution.

Hello,
Please check the following:
1 - The hardware configuration of the STM32H755: LDO, SMPS or what else?
From RM0399:
The firmware configuration of the power should reflect the hardware.
2 - Did you enable any of the flash protection features in option bytes ?

Make sure that your boot pin is high while your chip gets 3.3 volt stabily. Getting in DFU mode can sometimes be complex but you shouldn't give up trying it.

Hello,
Your problem is not clear to me.
On which part do you have the issue? On H7 or F3 device?
Which exact STM32H7 part number you are using?
What are the tools you are using?
Please provide more details of your environment and your issue!

On MCU -STM32H755IIT6-
I used USB and SW connections but PC didn't even detect the device...

Yes, I found the problem. System supply configuration was wrong...
