How do I drive the Nucleo_F722ZE board with the STLINK board removed?

[chulhoolim-nnftech]

Hi, everyone.

I cut the stlink board from my Nucleo-F722ZE board.

And I supplied 5V power through E5V of CN11 And JP3 was set to E5V.

I confirmed that the PWR LED was on.

But the embedded program did not run.

I confirmed that this Nucleo-F722ZE board receives MCO input from the STlink board. But now there is no stlink board on my Nucleo.

So, I decided to use the HSI clock rather than the HSE clock.

I set "HSE not used" according to the manual.

 

- SB148 and SB163 ON

-SB112 and SB149(MCO) OFF

-SB8 and SB9 removed

 

And  I enabled HSI in cubeIDE's clock setting.

 

My embedded program on my nucleo runs. But it stops at HAL_Delay().

What part is the problem?

Is the way I did it correct?

Hello @chulhoolim-nnftech and welcome to the community.

According to the image you shared there is something going wrong in your RCC config. You have an error in the configuration:

What message do you get when you pass the mouse cursor on the red square of HSI selection?

Thank you for your reply.

The message is "PLL Mux should have HSE as input"

But My nucleo board doesn't have an input oscillator. 

 Can't I use that "HSE not used"?

Could you please share your ioc file?

Ah. I pressed wrong " Accept as Solution" button. Sorry. 

Anyway Thank you very much!
