nucleo_f103rb blinky example cannot run

[zl3one6]

Describe the bug
Following the document, build and flash blinky example into ST Nucleo-F103RB development board, cannot watch LED working. Jumpers on the board are not changed. ST official demos downloaded by Keil MDK are working correctly. Debugger is ST-Link.

To Reproduce
Steps to reproduce the behavior:

1. mkdir build; cd build
2. cmake -GNinja -DBOARD=nucleo_f103rb ..
3. ninja
   ninja flash
4. See error

Environment (please complete the following information):

• OS: Ubuntu 18.04, Windows 10
• Zephyr SDK on Ubuntu, GCC arm embedded on Windows
• Zephyr 1.13.0 release

With a quick look on Nucleo's .dts the onboard LED is aliased to LED0 as needed by the blinky sample.

I do not have this Nucleo. So, for starters, could you please check the returning value of device_get_binding against NULL in the blinky code?

It is strange as it is working on my side, on top of master.
Can you check it is working on recent zephyr?

[zl3one6]

In version 1.13.0, the nucleo_f103rb.dts contains the following LED port definition:

leds {
	compatible = "gpio-leds";
	green_led_2: led@0 {
		gpios = <&gpioa 5 GPIO_INT_ACTIVE_HIGH>;
		label = "User LD2";
	};
};

It seems that the program does not hit the main function

[erwango]

So I tested back on 1.13, and it also works on my side.
What is the version of your nucleo? Mine is MB1136 rev c. (I don't think this can be the issue anyway, but ...)
You mention you tested on windows and Ubuntu and you have same issue on both environments?
Have you tested hello_world sample?
Finally, can you try to flash by .bin drag and drop on drive mounted when plugging?

It seems the clock configuration issue. It works now, thanks

[grybouilli]

For any further reference, here's a clock configuration that seems to work:
in the file ${zephyrproject_directory}/zephyr/boards/st/nucleo_f103rb/nucleo_f103rb.dts, put the following clock configuration (i removed the definition for clk_hse):

&clk_lsi {
    status = "okay";
};

&clk_hsi {
    clock-frequency = <DT_FREQ_M(8)>;
    status = "okay";
};

&pll {
    mul = <2>;
    clocks = <&clk_hsi>;
    status = "okay";
};

&rcc {
    clocks = <&pll>;
    clock-frequency = <DT_FREQ_M(8)>;
    ahb-prescaler = <1>;
    apb1-prescaler = <1>;
    apb2-prescaler = <1>;
    adc-prescaler = <2>;
};
