question

So, I managed to get hold of my files.
In /data/conf are all the usual settings that were saved, as you pointed out.

In /data there needs to be a file called rc.local
rc.local will get called at startup and then you can run a script like mine.
Also in /data you must keep copies of all of the files that you modified so that they can be copied back from /data if they get overwritten by an update.

My rc.local looks like this:

#!/bin/bash

# /data/vedirect_ports contains a third entry "TTYO5"
# which I use for my third VE.Direct port.
# If the files are different, then the copy in /data is copied to /etc/venus

if diff /data/vedirect_ports /etc/venus/vedirect_ports >/dev/null ;
then
echo "No change"
else
cp /data/vedirect_ports /etc/venus
echo "Copied vedirect_ports to /etc/venus"
fi

I have had this problem as well. I just found this post (and thus the culprit) that kept deleting my config for my 7" screen. I wrote a little script that sits in the u-boot folder (the boot partition) that handles my setup nicely. It reinstalls the opkg bits and pieces, runs a screen calibration, replaces the start-gui.sh script, renames the headless file to headless.off, and reboots the pi. I will automate it now, so it can check for the existance of the headless.off file, and if exist, exit, else run script at u-boot, using rc.local on each boot. If I turn on the backlight (hardware switch only) and see a touchscreen calibration on the panel, I know its updated.

For me is a little bit more complicated as I have a canbus BMS and a can interface which does not keep config after upgrade.

Here is the script, maybe help someone ...

#!/bin/bash

if diff /data/backup_custom_files/canbus_ports /etc/venus/canbus_ports > /home/root/post_upgrade.txt 2>&1 ;

then

echo "No change"

else

Hi All

Firstly id like to say thank you to everyone and my code/script below is hash up of different lines from lots of other peoples ones and a few lines ive added. so credit to lots of people thanks.

ok so..... I cant seem to get this to work?? first time it just went into a reboot loop, second time it just stopped at first splash screen (same as fresh image install), Third try it comes up with touch cal' screen but then reboots and starts looping cal'screen?

can any one please help and point me in the right direction? what i'm missing or what ive done wrong?

Thanks Mark

This is my rc.local

#The script exists in /data

#open an ssh to the device, and change directory to /data.

# cd /data

#then create a script called rc.local with nano

# nano rc.local

#fill the file with all the commands you need to make the system the way you like it then CTRL+O to save it then CTRL+X to exit

#then make the script executable.

# chmod 755 rc.local

#Any modified files will need to be also located in /data

#here is my version of the rc.local contents between the #####

#ive added a file called fw to /opt/victronenergy/gui/

####

if diff /data/backup/fw /opt/victronenergy/gui/fw >/dev/null;

then

echo "no software update detected, exiting"

Hi All

Re the latest script for the raspi, i have tested the latest version it reloads every thing now, all analog inputs, switching relays up to 6x now can be used ( have tested 8x) but over lapped the canbus control, canbus, display control and timers all functions, only a screen calibration to do on start up and auto reboots and you are away, The super user function is still there just enter a pass word only required if you want to log back on with WinSCP or Bitvise SSH etc

So all the opkg software updates as well are updated and installed

The VE can functions, the normal canbus functions OK with the Pylon tech and BYD lithium batteries etc.

Note: For this to work correctly you must have all the files & folders required to be saved in the data folder for the back up to work.

Tested script attached.

The commented out commands are for custom tiles settings only if required, (Mark Mevan from the UK) these are his custom tiles etc.

Enjoy

Update Script Rob Duthie Test Ver.txt

I made some edits to it to keep it simple for simpler installs.

Also here are the copy commands you need to do before the script will work properly.

cp /opt/victronenergy/gui/start-gui.sh /data/start-gui.sh

cp /etc/venus/backlight_device /data/backlight_device

cp /etc/venus/blank_display_device /data/blank_display_device

cp /etc/pointercal /data/pointercal

One addition is the pointercal data, copy that out and then replace it. If the position of the screen never changes and the screen never changes, no need to re run it.
