Problem with custom made Board und HiD Bootloader

[jenspogo]

Hey guys
I have designed my own STM32F103 Board as Raspberry Pi Extension with some additional Stuff like PWM up to 120W and Pmos Switches and som Inputs for Industrial 0-10V and 0-20mA input.
I also would like to use the Board with the HID bootloader from https://github.com/Serasidis/STM32_HID_Bootloader. I am able to programm the MCU with the ST-Link and I am also able to flash the bootloader. When I start Programming from the Arduino IDE, the board is recognized as a Bluepill (like i have planned) but programming gives an Error: Comport not found. I'am able to programm the Board with the ST Link and open the COM port to recieve Sensor Values- therefore it is not completely wrong designed.
I'm using an externel 24V Voltage Source. Is this the problem?

One would not think the input supply is an issue unless your 5V regulator is having an issue, but you may wish to look at the 5V and 3.3V outputs and verify with a scope that your supply voltage is noise free. Additionally, if your HAT is on the rPi, you may be getting some RF hash into the traces which can play havoc with the uC. You can try putting a grounded shield between the rPi and the HAT ... I have used this stuff in the past with great success:
https://www.google.com/search?&q=mu+metal
but,
you can also cover aluminum foil with package tape (use a single stranded copper wire against the foil before taping) as a simple test. The foil should be grounded at the rPi ground plane.

Usually when exploring these complicated things, I try and simplify the testing ... forget the rPi, forget the 24V and use a 9V or 12V drycell battery holder for C/D cells. Now you are dealing with a simply homemade board, a stable power source, no RF hash from the rPi ....
Just a thought.

Can you post the complete Arduino generated message?

After you burn the HID bootloader with ST-Link, try to upload a blink sketch with HID Bootloader by using the following settings

Hey everybody,
thanks for your replies
actually I just plugged in the USB - no other Supplies.

this are the Arduino Settings:

I have also tried the Maple bootloader with a positive result:

Done!

Resetting USB to switch back to runtime mode

the Code is the simple blink, with an added Serial.begin and Serial.println("Hello World");
Serial Monitor works. but there is still an error message which should not be there right?:

Code: Select all

error resetting after download: usb_reset: could not reset device, win error: Ein nicht vorhandenes Gerät wurde angegeben.

in Englisch it should be something like: error resetting after download: usb_reset: could not reset device, win error: A device that does not exist was specified.

what might be the Problem with the HID bootloader?

[jenspogo]

ok, strange...

first things first: It works right now - but I don't know why

Following things I have done with my three Boards and it works with every Board now:
programm the HID Bootloder (no programming possible, but I can read out the Serial.print stuff from programms programmed with ST Link)
programm the Maple Bootloarder - works fine
Programm the HID Bootloader - works pefectly ...

This is does not really mean an error, do not pay attention to this, the upload should be successful.
