Flash latency inconsistency between STM32CubeG4 and RM0440

Open aurel32 opened this issue 2 years ago • 1 comments

There is an inconsistency about between the flash latency in the LL_SetFlashLatency() function (file stm32g4xx_ll_utils.c) in STM32CubeG4 and the STM32 G4 Series Reference Manual. The configured wait states are for instance twice higher than in the reference manual for the maximum frequency of 170MHz. See:
