In trying to compile generated code from the STM32CubeMX application for the STM32F429I-DISCO board, I've found a problem with part of the HAL library.
Simply, the PLLSAI assert #defines have a bug in their definition:
/** @defgroup RCCEx_PLLSAI_Clock_Source
* @{
*/
#define IS_RCC_PLLSAIN_VALUE(VALUE) ((192 <= (VALUE)) && ((VALUE) <= 432))
#define IS_RCC_PLLSAIQ_VALUE(VALUE) ((2 <= (VALUE)) && ((VALUE) <= 15))
#define IS_RCC_PLLSAIR_VALUE(VALUE) ((2 <= (VALUE)) && ((VALUE) <= 7))
/**
* @}
*/
This is the same setting as the normal PLL configuration. However, the PLLSAI configuration allows for a looser 49-432 definition (see
http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/DM00031pdf
). So, this needs to be instead defined as,
#define IS_RCC_PLLSAIN_VALUE(VALUE) ((49 <= (VALUE)) && ((VALUE) <= 432))
This begs the question: Is there any formal way of reporting bugs with the ST provided libraries / tools, rather than just on the forums?
