In my Nucleo while debugging STLINK LD1(RED and GREEN) is not blinking

[msureshkumar2610]

In my Nucleo while debugging STLINK LD1(RED and GREEN) is not blinking. I study with some of documents. it is communication error, But the debugging is is normal

Please tell me what is the problem ? Any settings to change ?

I have attached the photo. Now nucleo is debugging mode

So st-link programming and debugging works okay but just the LED is unlit? Could probe the led to ensure it actually works. But I wouldn't spend time on it. There must be more important things to do.

Ok, But it seems communication error I think. Ok how to flash my nucleo with stm32cubeide without debugging ?

Try updating ST-LINK firmware to current.​

​

Can it run Cube Programmer?​

[msureshkumar2610]

No I did't tried yet. But I would like to stay inside only cubeide. I want to learn all the things this cubeide. It is good for me. I wont migrate from cubeide.

Because already switched form KEIL(without proper use). At least I would like to learn all the things using this cubeide.

Thanks @Community member​ and @TDK​ :)

And I have some of the questions.

How do I generate 2Mhz frequency using timer. What is the timer calculation ?

I got calculation like from youtube.

Peripheral clock/Desired clock = value = PSC*ARR

Is it Correct ?.

In PIC timer(8bit) I know well

that is (4/FXT)*A*(256-B)

where

FXT = external clock

A = PSC

B = Timer counter

(4/16Mhz)*32*(256-100) = 0.001248 Means timer over flow every 1us

But in STM32 it is different.

Please ket me know the calculation

Thanks to every one.
