I would like to completely update my old installation on Raspberry Pi 2, still with Jessie OS.
In the documentation of the pre-built image it is indicated that it is compatible with Pi3 and 4, so I cannot use it with Pi 2?
If I wanted to write the feeds on USB stick to further preserve the SD, what is the best way: to use the symbolic links or modify the paths in the settings file? In this case can I avoid creating the ext2 partition?
sorry if I asked trivial questions, I’m not an expert
The “fiddle” Brian refers to is one line in one file. After you’ve flashed the image to your SD card, and because it’s designed for a 16 GB but I could get 32 GB cheaper, with it still in the laptop, I expanded the partition with GParted. Then you need to find the file /boot/config.txt
find the line(s)
(the second line might not be there - can’t remember) and replace with
and of course save the file, put the SD card into the Pi and you’re away.
I’m not an emonCMS/Pi expert, so if you want to keep your data and dashboards, Brian is probably best placed to help you.
