WebDec 30, 2024 · If the Arduino core assumes a X3 crystal of 8MHz to create the HSE_XTAL+PLL config, that’s the fault. I assume it uses the same technique that the clock is actually sourced from the ST-Link and 8MHz crystal above and the STM32F4 chip directly gets the needed clock. I’ll double check the clock init code of the Arduino core. http://files.imtschool.com/ARM/Day%202/Slides/02-Clock%20Systems.pdf is charlie ely still married https://djfula.com
