Why doesn't my detached STLINK board recognize my nucleo_F722ZE board?

Hi.

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

But stlink doesn't recognize my board. Why?

I used an ats49 8Mhz 18pF crystal since there is no recommended crystal. C37 and C38 have 18pF attached.

HSE on-board oscillator from X3 crystal (not provided)

– SB148 and SB163 OFF
– SB8 and SB9 ON
– C37 and C38 soldered with 4.3 pF capacitors
– SB112 and SB149 OFF

I turned it on and tested it, but it's the same.

The below message is CubeIDE error messages.
