So to me that sounds like the core_freq (core frequency) is the frequency of the VPU core clock. And I would really like to know what impact the throttling has on the overall performance of the PI. i think its less that it throttles the core clock, and more that it just locks it to the fastest spee...

Well on the website (https://www.raspberrypi.org/documentation/configuration/uart.md) it says: In order to use the mini UART, you need to configure the Raspberry Pi to use a fixed VPU core clock frequency. This is because the mini UART clock is linked to the VPU core clock, so that when the core clo...

Hi all, I am not sure if this is the right section for posting this question but it seemed rather advanced for me so I am just gonna ask it here. I want to use the miniUART of a Raspberry Pi 4b 4GB and have not found too much information about the influence of setting the core frequency to 250 Mhz. ...
