rockpi4a @2GHz

dolphs · January 31, 2021

Hi,

Just noticed image " Linux rockpi-4a 5.9.14-rockchip64 #20.11.4 SMP PREEMPT Tue Dec 15 08:52:20 CET 2020 aarch64 GNU/Linux " my rockpi4a runs at 2Ghz.

To radxa overclocking is possible so that 2GHz is not a real surprise ...

Though checked " armbianEnv.txt " but did not find any "overlays" option present overlocking this board, neither any other files in /boot ( or /boot/dtb/rockchip/overlay ).

However building a custom image ( kernel 5.10 ) it is running at 1,8GHz again, how can I set this to 2GHz ?

( as a side note - tehre is no need to enable panfrost BTW as I run this as a headless server )

Thanks

Not sure but I think @TonyMac32 did adjustments to rockchip a while ago including making the 2.0 OC optional as overlay...

Providing logs with

armbianmonitor -u

helps with troubleshooting and significantly raises chances that issue gets addressed.

no url to paste to, but 5.9.14 shows:

It is not a biggie, but just noticed and that is all.

So I suppose it is a WIP and will be overlay sooner or later ( similar back then with NEO2 board : cpu-clock-1.3GHz-1.3v )
