Setting CPU clock to 2.0 GHz on Lichee Pi 4A-16G

[cmd0s]

Hi everyone,

I need help setting the CPU clock frequency to 2.0 GHz on my Lichee Pi 4A-16G. I’ve tried modifying the .dtb/.dts files, but so far, it hasn’t worked. I also attempted to search online for a solution, but unfortunately, I couldn’t find anything that helped.

Here’s some system info:

OS: Linux revyos-lpi4a 5.10.113-th1520 #2024.07.20.13.28+d8f77de53

If anyone has experience with this board or knows how to properly adjust the CPU clock settings, I’d greatly appreciate your guidance.

Thank you in advance!

Theoretically, modifying the device tree is feasible, but it is not 100% successful. In some cases, the system may crash due to chip problems. Perhaps you can show how you modified it to see if it is correct?

Hi, how's the testing going? By the way, we've released a new image; feel free to give it a try!
