Hi,
Title is fairly self-explanatory but just to be clear, I've got the default Ubuntu-based image installed on an SD card. What I'd like to be able to do is mount this SD card on a computer and alter the configuration files there without needing to boot the Parallella (I have good reasons for this, mainly due to lack of HDMI monitor, or any suitable monitor for that matter).
Currently when I mount the SD card I see 3 files; devicetree.dtb, parallella.bit.bin and uImage. If I wanted to alter network settings in order to automatically connect to a wireless network, how would I go about this? I'm not expecting anyone to give me a point by point guide on how to do this, but some advice on how to get started would be welcome. Thanks.
