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

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?

Hi, again.

I did "HSE on-board oscillator from X3 crystal (not provided)" on um1974-stm32.

But stlink doesn't recognize my board. Why?
