Hello, please help me with crystal:
ABM3B-26.000MHZ-10-1-U-T
Is it connectd correctly? It's not working at all. Never seen one pin connetcion like RCC_CK_IN_PA0.

no.
this is a crystal, need two pins conn. to oszillator.
+
but in Cube you set input for oszillator, also your connecting 3v3 for oszillator.
but probably wrong pinout, to use standard oszillator.
-> you should decide, what you wanna use now: crystal or oszillator ?
then use some oszillator also...
maybe you should first read+learn a little bit about processors and chips... 🙂

Thanks but nothing new. I have only one pin and this is why I am here.

ok, so use an oszillator .

The ABM3B-26.000MHZ-10-1-U-T is not a oszillator is crystal. It has 2 and 4 GND pins and 1 and 3 of crystal connection. My STM32 has only one pin for high speed crystal like shown on the CAD and CubeMX. Before this post I tryed to conect it to low speed 2 pins and it does't worked. I am very confused and dissapointed. Any way thanks for your posts.

If I change it for example to SiT8208AI-3F-33E-25.000000X is it will work?

>>I am very confused and disappointed.
Why, because you have a device that takes a singular input, and you're trying to connect something that doesn't work that way? You need something that outputs a clock when powered.

That seems more appropriate, or a TCXO

right.
but expensive...look: mouser , 815-ASFL3-25.0M-EK-T ; 25.0000MHZ CMOS SMD, 5 mm x 3.2 mm , 1,02 € .
but look on your pinout - wrong connection on oscillator will not work, just destroy it.
