Hi, I'm having issue with external clock of STM32F769NI. When I run the code, it's getting stuck on HSERDY register. I added the schematic.

Try removing R73. Why is it there?

What is the load capacitance of X1? Would have been useful to include part number.

Hi,

I just removed the resistor and nothing happened. I also changed the MCU just in case.

Part number is here: ABM8AIG-25.000MHZ-12-2Z-T3

Also I attached the full schematic.

Hi,

I re-soldered all the MCU components but I couldn't measure the voltage on DSI12 pins. When I connect them together I can't run the code. I have to split the DSI12 pins. Can you please share the DSI12 pins effect on oscillator ?

Thanks

Connecting VDD12DSI and VCAPDSI to 3.3V doesn't look right.

 

Any STM32 pin with a "12" in its name typically wants to live around 1.2V. Similar for "33" and 3.3V.
