Hello-
Working with the STM32F411 on the ST F411 Discovery board, we have set the speed to 72MHz using the HSI as the PLL source. The register values are as follows:
RCC->CR = 0x03005C83
RCC->PLLCFGR = 0x23001208
According to Cube, this configuration is invalid:
In fact, there seems to be NO clock speed we can find that won't flag the configuration as invalid if HSI is the PLL source. Although the code appears to run correctly and there haven't been any timing issues experienced we want to check if there is some additional clock setting someplace that needs to be used to stop Cube from flagging this as an error. Current version of cube is:
STM32CubeIDE
Version: 1.15.0
Build: 20695_20240315_1429 (UTC)
But this issue is not new, it has happened on older versions as well.
