See the RCC_PLLCFGR section in the TRM (relevant image attached).

https://github.com/ArduPilot/ChibiOS.sv ... 0C4-L170C5

Code: Select all

#define STM32_PLLVCO_MIN        192000000


Should be 100MHz

DS and RM do not agree on that value, I am changing it like you suggested. Usually I take those limits from the DS.
