I have a question about systick timer load value calculation.
You can see at STM32F4 reference manual(RM0090) clock scheme (5.2, fig.9), that Cortex system timer frequency is equal HCLK frequency divided by 8.
Therefore I think, systick load value should be calculated as HCLK / (8 * CH_FREQUENCY ...
