[solved] Programming a diymore STM32F407VET6 board with DFU over USB

[psysc0rpi0n]

Hi.
I bought a similar board to this one quite some time ago:
https://www.diymore.cc/products/stm32f4-discovery-stm32f407vgt6-microcontroller-32bit-flash-mcu-arm-cortex-m4-core-development-board
I say similar because the one I bought seems not available anymore there and, instead, they have that VGT6 instead of VET6 (mine).

I never used it before but today I decided to spend some time with it.

I found this example code to make PC8 blink. I just changed the frequency to be able to check the blinking/toggling with a DMM becaus emy scope is actually at work.

Code: [Select]

void setup() {
  pinMode(PC8, OUTPUT);
}

void loop() {
  digitalWrite(PC8,HIGH);
  delay(10);
  digitalWrite(PC8,LOW);
  delay(10);
}

I compiled it with Arduino IDE and used the generated .elf file to upload it to the board.

To program the board we wactually must pull BOOT1 pin to LOW and only then plug in the USB cable. Then we can see the device in DFU mode with:

Code: [Select]

$ lsusb
Bus 002 Device 070: ID 0483:df11 STMicroelectronics STM Device in DFU Mode
$_

Then I installed dfu-util and tried to talk with the device:

Code: [Select]

$ sudo dfu-util --list
Found DFU: [0483:df11] ver=2200, devnum=70, cfg=1, intf=0, path="2-1", alt=3, name="@Device Feature/0xFFFF0000/01*004 e", serial="3962374B3238"

This is exactly the same:

Code: [Select]

sudo dfu-util --download /tmp/arduino/sketches/565B457541832EAED9889914CDFB6C29/test.ino.elf --device=0483:df11 -a 0 --dfuse-address 0x08000000

The -a 0 is just an alias for the longer version above.

After this, we need to remove the pull-down from BOOT1, pull down BOOT0, unplug and plugin the USB cable and press the reset button to make the program run. So I did, and then I checked with the DMM if PC8 was toggling or not. It wasn't.

So, next I tried STM32CubeProgrammer. BOOT1 to low, unplug and plugin USB cable, press reset and connect to the device in STM32CubeProgrammer. Then selected the file and hit "Start programming". When it finished, again remove BOOT1 pull down, pull down BOOT0, unplug and plugin USB and press reset. Check PC8 with DMM and it is actually toggling.

So, where did I go wrong with dfu-util?

I don't think that dfu-util can parse ELF files, so you'll have to convert it to a raw image or DfuSe first.

I'm using the .bin file with dfu-util

Just generate with objcopy from the elf

Are you really?
From the command lines you have posted it would seem you are using the .elf file, and dfu-util is complaining, also, notice the size!
I suspect that more than 600 kB for a blinky is a bit excessive even for an Arduino framework.

Yeah, you're right. I0m actually using the .elf file, not the .bin

In that case I'm going to try the .bin file that Arduino IDE also generates!

Edited;
And yes, the binary file is working in the same way as the STM32CubeProgrammer do!

Thanks for the help to those 3 kind persons!
