'DT_N_S_soc_S_timers_40012c00_S_pwm' undeclared

[zzzh]

Describe the bug
Got compile error when trying to move code from zephyr-2.3.0 to zephyr-3.0.99

Please also mention any information which could help others to understand
the problem you're facing:

• What target platform are you using? ARM-STM32F0
• What have you tried to diagnose or workaround this issue? changing dts file
• changed as an example in sample, but don't work

To Reproduce
Steps to reproduce the behavior:
in my project folder, run west build, then error as below would appear:

my_project_path/build/zephyr/include/generated/devicetree_unfixed.h:4751:54: error: 'DT_N_S_soc_S_timers_40012c00_S_pwm' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_timers_40012c00_S_pwm_ORD'?
4751 | #define DT_N_S_pwmleds_S_pwm_led_all_P_pwms_IDX_0_PH DT_N_S_soc_S_timers_40012c00_S_pwm

Expected behavior
A clear and concise description of what you expected to happen.
No error

Impact
What impact does this issue have on your progress (e.g., annoyance, showstopper)
Can't continue

Logs and console output
If applicable, add console logs or other types of debug information
e.g Wireshark capture or Logic analyzer capture (upload in zip archive).
copy-and-paste text and put a code fence (```) before and after, to help
explain the issue. (if unable to obtain text log, add a screenshot)

Environment (please complete the following information):

• OS: (e.g. Linux, MacOS, Windows) Linux
• Toolchain (e.g Zephyr SDK, ...) Zephyr SDK
• Commit SHA or Version used zephyr-3.0.99

Additional context
Add any other context that could be relevant to your issue, such as pin setting,
target configuration, ...

code in dts file:

&timers1 {
//st,prescaler = <10000>;
status = "okay";

pwm1: pwm {
    status = "okay";        
    pinctrl-0 = <&tim1_ch4_pa11 &tim1_ch3n_pb15 &tim1_ch2n_pb14 &tim1_ch1n_pb13>;
    pinctrl-names = "default";
};

};

Can you clarify which board you're using ? ARM-STM32F0 is not an official board name

[zzzh]

It's not an official board, but compile well in zephyr-2.3, some pinctrl thing had been added.

[zzzh]

DT_PWMS_LABEL is deprecated, which command should be used instead?

[erwango]

DT_PWMS_LABEL is deprecated, which command should be used instead?

It depends what you need to do. Do you have an example of usage ?

[erwango]

Should be something like DT_PWMS_CTLR

[zzzh]

I used DT_PWMS_CTLR to replace DT_PWMS_LABEL, seems this is the source of the error.

for example:
it was: DT_PWMS_LABEL(DT_NODALABEL(xxx)), and work well in zephyr-2.3
now is: DT_PWMS_CTLR(DT_NODALABEL(xxx)), and don't work in zephyr-3.0.99

[erwango]

I suggest to look at samples/basic/blinky_pwm/src/main.c to see how it is used in current code.

[zzzh]

Got it, thank you.

[zzzh]

@erwango
I tried the way in example, it don't work.
Got undeclared issue in compile.

[erwango]

I've transfered this to discussions, as it is likely not a bug so far.
Can you provide the code you're using ?

[zzzh]

Got same error as before

[erwango]

ok, then I suggest comparing nucleo_f031k6 with your board. Unfortunately, I won't be able to help here.

[erwango]

@zzzh You mention you have the following in your dts file:

timers1: timers@40012c00 {
compatible = "st,stm32-timers";
reg = <0x40012c00 0x400>;
clocks = <&rcc STM32_CLOCK_BUS_APB1_2 0x00000800>;
interrupts = <13 0>, <14 0>;
interrupt-names = "brk_up_trg_com", "cc";
st,prescaler = <0>;
status = "disabled";
label = "TIMERS_1";

Is that in your board dts file ?
Normally, you shouldn't need to add it as it should be provided in soc.dtsi file.

[zzzh]

@erwango It's from the dtsi file, just put it there to make things clear.

[erwango]

ok. Don't hesitate to provide maximum details in problem description.
The kind of issue you're facing is one of those hiding in such details.
