That is the ST-link V3 on NUCLEO-H755ZI board.The HSE MCO option is set to HSE/3, how to change it to HSE/5.Usually this is configurable in code, but this is ST-link firmware. If there is a way to change the division value, please some one let me kno...

Actually, I figured out that using the fractional part of the PLL could achieve a good result.Using the following configuration:DIVM1: 3DIVN1: 345FRACN1: 4915DIVP1: 2The equation is: input_frequency / DIVM1 * (DIVN1 + FRACN1 / 2^13) / DIVP1This would...

The STLINK-V3 chip is STM32F723IE, and by referring to the (MB1363-H755ZIQ-D01_Schematic) sheet 9 (also page 9) which contains (STLINK_V3E), it shows: By further referring to the datasheet (page 76), it shows: Now, by looking at page 144 in the Refer...

Here it is.I would like to get some thing accurate that could be multiplied to get 480MHz.The PLL allows maximum multiplication of 512, which should produce (in my case) 960MHz, after that there is a /2 divider.A PLL pre-division also exist.DIVM1: / ...
