Arduino for STM32

I will give it a try in the future, but the Makefile works great. I will be recommending these posts.

I followed your instructions and now I am able to flash through the micro usb.
The only command that did not work was dfu-util -l (did not show a list), but everything else worked.
Thanks

For informational purposes, I flash the broad using the dongle on pins(pa9 tx, pa10 rx). Can you flash the broad using the micro usb?

Success! It comes up as; /dev/ttyACM0

I am sorry, I did not know there was another page started.
dmesg:
[ 562.369009] usb 1-2: new full-speed USB device number 9 using xhci_hcd
[ 562.522910] usb 1-2: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00
[ 562.522930] usb 1-2: New USB device strings: Mfr=1, Product=2 ...

For some reason it shows up as "/dev/ttyUSB0", but I can not connect to it.

I usually put a new folder in the root/package directory and have the new directory makefile point to root directory Make.rules file.

Looks good. I am pretty new to programming. So I do not know of many of the flags that are to be use, but I am learning. I am trying to figure why the serial interfaces are not working (Serial.begin(115200)). I guest I will eventually figure it out.

Problem solved!
Changed -DVECT_TAB_ADDR=0x8002000 to -DVECT_TAB_ADDR=0x8000000

Correction code:
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin PB1 as an output.
pinMode(PC13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(PC13, HIGH); // turn the LED on (HIGH is ...
