Posted on April 10, 2018 at 15:32Why does the STM32CubeMX tool in my Nucleo-L4R5ZI-based project disallow HCLK frequencies below 15 MHz? According to the datasheet frequencies as low as 100 kHz should be possible.When writing this: The current eclip...

Posted on April 10, 2018 at 15:17In the clock tree configuration for the STM32L4R5ZI the CubeMX tool only allows for frequencies >14 MHz for the HCLK subsystem. For lower clock frequencies the HCLK window is marked in red (illegal configuration).In ...
