alternative way to use STM DFU in Arduino 1.8.3 on Black F407VET6

https://hackaday.io/project/4139-stm32- … -converter

create a directory in <user>\Documents\Arduino\hardware\Arduino_STM32-master\tools\win\stfdu
unzip to “stfdu” directory

modify the platform.txt in Arduino\hardware\Arduino_STM32-master\STM32F4

change the compiler from binary to ihex , because the upload tools required.
compiler.elf2hex.flags=-O ihex
compiler.elf2hex.cmd=arm-none-eabi-objcopy

PS: I wonder how do I make USB serial work in DFU download.

You have to add -DSERIAL_USB to the cpu_flags in “boards.txt”:
generic_f407v.menu.usb_cfg.usb_dfu.build.cpu_flags=-DSERIAL_USB

I did try before adding -DSERIAL_USB in cpu_flags but it wont compile at all !!

Please post here the complete build output, including any error/warning message.

Or do you mean that USB serial will not work?

DSERIAL_USB.txt

I found something strange !!
if I comment out
//Serial.begin(115200);
//Serial.println(“OK!!!!!!!!!!”);
complete build will fine and STM serial came out

if I use SerialUSB or Serial complete build OK but not working
SerialUSB.begin(115200);
SerialUSB.println(“OK!!!!!!!!!!”);

after few round of test and yes it work on you repo but not work on Roger’s repo

thanks again.

byte LED_BUILTIN2 = PA7;
byte LED_BUILTIN1 = PA6;
// the setup function runs once when you press reset or power the board
void setup() {
//setupUSB();
// initialize digital pin LED_BUILTIN as an output.
//delay(3000);
SerialUSB.begin(115200);
//delay(3000);
SerialUSB.println("OK!!");

pinMode(LED_BUILTIN1, OUTPUT);
pinMode(LED_BUILTIN2, OUTPUT);

}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN2, HIGH); // turn the LED on (HIGH is the voltage level)
SerialUSB.println("OK!!");
delay(100); // wait for a second
digitalWrite(LED_BUILTIN1, HIGH); // turn the LED off by making the voltage LOW
SerialUSB.println("OK!!");
delay(100); // wait for a second
digitalWrite(LED_BUILTIN2, LOW); // turn the LED on (HIGH is the voltage level)
SerialUSB.println("OK!!");
delay(100); // wait for a second
digitalWrite(LED_BUILTIN1, LOW); // turn the LED off by making the voltage LOW
delay(100); // wait for a second

}

• My first question goes back to what happens before the start of the instructions at the start of the thread. I have installed dfu-util and can run it from Terminal.app, but I do not see “STM DFU” as an upload option in the IDE. Is there another step required to link the DFU utility into the IDE? Do I need an additional program such as DFU-Programmer / DfuSe?

• As I am not familiar with the board you are using, can you explain the significance of connecting PA0 to BOOT0?

• … and what does the “K_UP” button do?

Cheers,
Andy

“My” board is different in that BOOT0 and BOOT1 are pulled up by default. Jumpers are used to pull them down when needed. As I understand it, we don’t need to do anything with PA0 as the board internal power regulator will be on anyway (BYPASS_REG is not available on the F407V — i.e. 100-pin — packages). So I guess I can just run the DFU procedure with a jumper on BOOT1 to pull it down and set the mode to “boot from system memory”; then switch the jumper to BOOT0 to set the mode to “boot from flash memory” — which is the same procedure for any loading method.

Thanks for the clarification.
