How to overclock Banana Pi with stable Armbian Linux version 4.19.62-sunxi

August 22, 20197 yr

Hi enthusiast,

Last few year I used Armbian 5.25, which allow me to echo cpufreq into /sys/devices/system/cpu/cpu0/cpufreq/scaling_***_freq to choose the overclock freq. However, last week, I had to disconnect the power and the Banana Pi didn't boot again. So I decided to install a fresh updated version of Armbian, which is called Bionic. The /proc/version shows:

Linux version 4.19.62-sunxi (root@armbian.com) (gcc version 7.4.1 20181213 [linaro-7.4-2019.02 revision 56ec6f6b99cc167ff0c2f8e1a2eed33b1edc85d4] (Linaro GCC 7.4-2019.02)) #5.92 SMP Wed Jul 31 22:07:23 CEST 2019

But now, when I want to overclock by using the method above, it won't allow me to go beyond 960MHz. That's the maximum. I was able to have stable system at 1152MHz in older version of Armbian 5.25 (Debian_jessie_default_3.4.113).

I found a post: http://forum.lemaker.org/thread-15543-1-1.html, but I don't know how to edit the file he mentioned in that post. Is it able to edit that file now? As I have set up everything now.

So the question is, how to overclock my Banana Pi to 1152MHz in Armbian Bionic (Linux version 4.19.62-sunxi)?

Thank you so much.

Hi there, I must have missed that when tried to figure out, probably because it showing in H5 & A64 subforum so I just automatically ignored it. Thanks for pointing out.

However, when I do the command

dtc -I dtb -O dts /boot/dtb-4.19.62-sunxi/sun7i-a20-bananapi.dtb -o /root/sun7i-a20-bananapi.dts

It showing this error:

So I don't know what happen? My board is the very first one Banana Pi M1.

I don't know. You will need to investigate/search deeper. IIRC its limited in u-boot.

P.S.

Its not worth doing that since you play with stability. Some chips will work, other don't.

Yeah cause I know mine will work as I have used it on older version of Armbian, 5.25 to be exact. But when I decide to upgrade, I'm stuck at this. So any help would be appreciate.

By the way, is the file I am using correct /boot/dtb-4.19.62-sunxi/sun7i-a20-bananapi.dtb ?

Is there anyone has successful in getting Banana Pi (Armbian 4.19.62-sunxi) overclocking at 1.152GHz ? Please guide me how to do it. Thank you so much.

I have tried to search for how to edit uboot, and find a post about Building Armbian. In the github, I find this file: build/config/sources/sun7i.conf, in there, has this section:

case $BRANCH in
	default)
	KERNELSOURCE='https://github.com/linux-sunxi/linux-sunxi'
	KERNELBRANCH='branch:sunxi-3.4'
	KERNELDIR='linux-sunxi'
	KERNEL_USE_GCC='> 5.0'

	CPUMAX=1010000
	;;

	next)
	CPUMAX=960000

	ASOUND_STATE='asound.state.sunxi-next'
	;;
esac

Is this the ones that limiting the cpu frequency to 960000? If I change this CPUMAX=960000 to CPUMAX=1152000, will the Armbian is able to run at 1.152HGHz? But what Kernel is this build, 3.4 or the Bionic 4.19.xx?

Thank you so much.

Also you need to adjust voltage controller as below. I also attached my dtb file.

Goodluck. If you find something useful please let me know.

Thank you so much djdeeles, your comment is very helpful, directly solved into the problem, better than someone's answer (not pointed out the main issue for regular user, who not have much experience like him).

By the way, I just tried with your dtb on Armbian Buster


sbc-bench v0.7.5 LeMaker Banana Pi (Sun, 06 Dec 2020 06:24:37 +0000) Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster

This is the result of sbc-bench v0.7.5 from tkaiser github: http://ix.io/2GOK

I am not sure if your dtb is from Debian 9 or 10 image, but it works for me. So again, thanks for your post.

MERRY CHRISTMAS and HAPPY NEW YEAR all of you!

As you see the timestamp, I just freshly install the system and copy your dtb to the /boot, then install the script sbc-bench.sh, run it. After it finish, came to this post and wrote a result. I have not done any stability test yet. But if you have any recommended test, I'd love to do it now.

However, 2 years ago, I test the board BPi M1 on Armbian 5.25, my board is only stable at 1.152GHz.

So any suggestion for pushing its limitation, I will do it.

As you see the timestamp, I just freshly install the system and copy your dtb to the /boot, then install the script sbc-bench.sh, run it. After it finish, came to this post and wrote a result. I have not done any stability test yet. But if you have any recommended test, I'd love to do it now.

However, 2 years ago, I test the board BPi M1 on Armbian 5.25, my board is only stable at 1.152GHz.

So any suggestion for pushing its limitation, I will do it.

It's stable up to 1200mhz at stress tests but after days or several hours with no load it kernel panics. I cant solve problem.

If its related with overclock or not. It's drive me crazy.

I tried different kernel versions and u-boot but no lock...

Solved!

Clean latest version install armbian on BananaPI solved my problem.

It now runs 1.3 GHz fully stable @ 1.6 volts. Currently uptime 4 days.
