I have several NUCLEO-H755ZI-Q boards, the documentation says that the clock coming out from STLINK should be 25MHz but I meassured STLK_MCO and found an 8MHz signal... on SB72 to be more precise.
The sticker on the boards say
NUCLEO-H755ZI-Q
NUH755ZIQ$AT3
I was having issues when using HSE as a clock source, because I was configuring it to 25MHz as stated in the documentation and as it defaults to in CUBEMX... The issues went away when I set it to 8MHz.
Under the microscope X1 crystal shows 25.000.
Is there something to configure on STLINK to get the 25MHz?
Could the board be fake?
