STM32 Blue / black pill dfu upload and usb serial problems #207

Closed kloppertje closed 5 years ago

kloppertje commented 5 years ago

Some time ago I tried to get a black pill board (STM32F103C8T6) running under platformio. I can upload fine via STLinkV2 (clone). However, if I try to send some data over the emulated USB port, it doesn't work. After plugging in the USB cable, I get a Windows eeror message "unknown usb device (device descriptor request failed)".

Also, when trying to upload using DFU, things go wrong. I can flash the DFU bootloader, and select dfu as upload method in PIO. After flashing the bootloader, a "Maple DFU" device is seen in the category libusb-win32 devices in the device manager on Windows. However, after flashing once from PIO using DFU, the same error as above appears. The fact that the Maple DFU device appears confirms proper operiation of the USB port.

Something seems wrong with the bootloader; I don't know what though. The behaviour is the same for two different black pill boards.

Some more info: apparently, the serial data is visible on PA9 (TX1), when using Serial.print() or Serial1.print(). Might provide some useful info.

platformio.ini: [env:bluepill_f103c8] platform = ststm32 ; platform = https://github.com/platformio/platform-ststm32.git board = bluepill_f103c8 ; board = genericSTM32F103C8 framework = arduino ; upload_protocol = stlink upload_protocol = dfu upload_port = anything

main.cpp:

include

define LED_PIN PB12

void setup() { // Serial.begin(115200); pinMode(LED_PIN, OUTPUT); }

void loop() { digitalWrite(LED_PIN, 1); delay(900); digitalWrite(LED_PIN, 0); delay(100); // Serial.println("abc"); }

Hi @kloppertje! Thank for the report. Could you please try the next experiment:

  1. Delete current platform pio platform uninstall ststm32 (Please make sure there is no other ststm32 folders in PlatformIO home dir C:\Users\YOUR_USER\.platformio\platforms)
  2. Delete stm32 related packages from C:\Users\YOUR_USER\.platformio\packages (like framework-arduinoststm32*) and toolchain toolchain-gccarmnoneeabi
  3. Install the latest platform from the dev branch pio platform install https://github.com/platformio/platform-ststm32,git
  4. Burn bootloader to your board.
  5. Compile and upload firmware in verbose mode (pio run -e genericSTM32F103C8 -v) with this configuration: 
    [env: genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduino
upload_protocol = dfu
  6. Describe here results and attach the entire log somewhere.

Thanks in advance! BTW, does everything work in Arduino IDE?

kloppertje commented 5 years ago

Hi @valeros, thanks for the quick reply! I've executed all of the steps described above. See attached log for the command line output.

And now it suddenly works! The serial device is visible after uploading, and the serial port outputs data. Is this solely due to the switch from stm32(duino) core to the maple core? The bluepill (and blackpill since one of the latest ststm32 platform versions) definitions use stm32(duino) core, while genericSTM32F103C8 usees maple core, according to the board definitions.

IIRC everything was working fine in Arduino IDE (was some time ago since I last used it in there). verboseOutput.txt

pfeerick commented 5 years ago

This is probably another of those "use the board_build.core = maple if wanting to use DFU cases", so should be able to be closed now. Going from this PR we may be able to use the 'official' stm32duino core soon with DFU...

valeros commented 5 years ago

Please reopen the issue if you still have any problems.

me21 commented 5 years ago

I think installing from git is not necessary now because there's version 5.3.0.

mikegleasonjr commented 4 years ago

Oh my god, I spent hours trying to figure out why the serial was disappearing after

  1. uploading my first sketch AND
  2. resetting the board (or unplugging/re-plugging it)

Thank you so much!

@valeros Hi, I am having a similar problem. I can't seem to upload to my STM32F103C8T6 over USB. I tried the steps you suggested, but to no avail.

My platformio.ini:

[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduino
upload_protocol = dfu
board_build.core = maple

If I run pio run -e genericSTM32F103C8 -v:

If I open a serial:

Congratulations, you have installed the STM32duino bootloader
See https://github.com/rogerclarkmelbourne/STM32duino-bootloader

For more information about Arduino on STM32
See https://www.stm32duino.com

Any clue as to why I can't upload?

To me the discrepancy between dfu-util version 0.7 and 1.9.2 stands out in the logs, but I am not sure if that is the problem.
