First, congrats on the release , I've been testing it on a A20-OLinuXino-LIME2-e16Gs16M (rev.K) since last week and it seems to be working fine , I have a couple of questions though.

* When the image boots, I get this message on the serial terminal (also through dmesg)

I was worried seeing this message because I use both 1c28c00.serial and 1c29000.serial on my setup, but I tested reading through both serial ports and they seem to work fine. What does this message means? will it affect those serial ports in any way?

* The olimex-copy scripts works fine to install the image into the internal flash, but is there a way to copy the image so it boots from an external hard drive?

Can you try apt update and apt upgrade and check if the serial issue persists?


You can't boot from external hard drive but you can transfer the file system there. I've added in our list of features requested, will see what we can do it to add in the scripts as an option to copy the file system to a hard drive.
