SystemClock_Config() crashing on discovery

[AGaru]

Hi everyone,

SystemClock_Config() works on Nucleo-144 board but not on Discovery even though they both have a F746 mcu on them.

Different HSE clock speeds? 8 MHz vs 25 MHz, check PLL-M setting, and the define for HSE_VALUE

Thank you i will investigate on it

Hi! the problem was due to the different flash latencies on the boards. I had to change the latency value given to this function.

HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_7);
