Hi!

Could you try my h3control dashboard? The thread
Looking forward for feedback on the thread by link above

Installation is pretty ease. just copy code in the bash console.

Hi

How do i use the onboard flash.
Um,
what are the must do updates and tweaks for a begginner.

I could suggest this checklist:
1. Move $HOME to internal flash. Without this step both chrome and firefox are useless. Due to slow speed of the fastest microsd.
2. Check /var/log and /tmp are tmpfs. It will significantly increase lifetime of your microsd.
3. Create swap on internal flash. Without it some rare operations fail in my scenarios.
4. Create 3 shortcuts on your PC to PI: ssh-connection, VNC-connection & h3control dashboard

Have you done it?

Regards

Oh wow thanks, I have entire system on internal flash, i assume that will give the same benefit in speed? ( I don't know how to install chrome or firefox, i accidentally installed firefox somehow by using sources for ubuntu or something i forget ( I ruined that system with lots of mistakes and did fresh install)
I'm not sure what you mean by 2. check...., i should read the contents.... i don't understand.
if i am running from internal, do i need to change swap at all, or is this just for speed and space?.
ooooo where do i find h3control? in sbin?
sorry if that makes no sense I'm a n0000b.

Ohhhhhhhh

I'm not sure what you mean by 2. check...., i should read the contents.... i don't understand.

First, check these two lines are present in /etc/fstab

tmpfs /tmp tmpfs nodev,nosuid,mode=1777 0 0
tmpfs /var/log tmpfs defaults,noatime,nosuid,mode=0755,size=500m 0 0

Copy code

Finally, copy 3 lines into bash.

sudo rm -rf /tmp/*
sudo rm -rf /var/log/*
sudo mount -a

Copy code

it will move two folders into RAM both immediately and after each reboot.

if i am running from internal, do i need to change swap at all, or is this just for speed and space?.

System allows to utilize 3Gb of RAM+SWAP for applications. If some app need more memory, we create swap file(s). Just for working

Here is a sample of new 500Mbytes swap located at /swap file (as root). Its a shell script

dd if=/dev/zero of=/swap bs=1M count=500
mkswap /swap
swapon /swap

Copy code

ooooo where do i find h3control? in sbin?

Im pretty shure /sbin is location of apps for root only
See description and screnshot on my thread and my first reply: http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=645&page=1&extra=#pid5844
That code in my first reply is an installer of h3control. Could you try it? All i need in a feedback is "All the fine!"

Hi, igorpec. I installed Armbian for OPI-Lite, and I backed the image with commands below but after restore I got only read filesystem and unexpanded partition issues.

dd if=/dev/sdb of=bak.img bs=1M count=3705

Copy code

Here is the UART debug info from first boot. No first boot script runs as the Armbian from official image.

Any fix?

Huh. I guess you corrupt your image during backup / restore. I hope you don't need to rescue some valuable date?
Try to fix filesystem on some other Linux comp with fsck -f, create file /forcefsck to force filesystem check on next boot.

That would be not possible. I got a failed message as below during boot.

[FAILED]Failed to start update UTMP about System Runlevel Changes...
See "systemctl status systemd-update-utmp-runlevel.service" for details.

Copy code

P.S. I got it solved with fsck -f. But log into Orangepi accout tells me there is no ~/orangepi directory now. How to run the first boot script which creats new account and resize filesystem?I creat a orangepi folder inside home directory and run starx with orangepi account but I got ths error below.

xauth: timeout in locking authority file /home/orangepi/.Xauthority

Copy code

Root accout runs fine now.
