Resolved! STM32MP1 - I2C frequency too low

In my device tree, we config 400KHz, but on scope we see only ~ 50Hz, and the clock seems weird. Anyone know why? &i2c1 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&i2c1_pins_a>; pinctrl-1 = <&i2c1_sleep_pins_a>; i2c-scl-rising-time-ns = <185>...

Resolved! How to check, and eventually enforce Performance governor on STM32MP15 openst-linux?

I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.Wh...
