I too have been trying the pivot-overlay approach to expand my root fiilesystem so that I may add new development tools.
I am able to 'see', mount, and touch my ext4 formatted USB drive, but I am not able to edit my /etc/config/fstab file, since the partition is reported as 'read-only'. What am I missing? How can I get around this?
@Justin-Sowers Fair enough. Sorry I wasn't able to help.
fast-gpio set 6 1 should not be creating any additional processes. It just uses hardware memory register access to set the pin value (as does the get-direction calls - only pwm causes fast-gpio to fork a separate process).
So, it is a bit of a puzzle as to why you end up with multiple processes running.
Since I really don't have any experience with Ruby or Python which you say you are using all I can suggest is that you look at what Ruby or Python are doing when they run the shell command fast-gpio set 6 1 etc. Perhaps others with more knowledge of these could advise.
Hi @Chad-Hadsell, The sound you are hearing is probably coming from the oscillator. A few people have reported this phenomenon, but so far it doesn't seem that it there's any side effect associated with it.
Hi Boken Lin,
Thanks for your reply and yes I would like to see if it would be possible to cross-compile smbus-cffi on the Omega. smbus-cffi according to their site is just "cffi (C foreign function interface)-based python reimplementation of the python-smbus C-extension" : https://pypi.python.org/pypi/smbus-cffi
and the only reason that I'm interested in this module is just because It's one of the requirements for installing TSL2591 module.
It'll be awesome if there would a work around to compile this module somehow...Thanks.
