Run scripts automatically at boot time #6

Open briantdavis opened 8 years ago

briantdavis commented 8 years ago

At the moment I need to run the "Enable_i2c" script as root each time I power-on the BBB to enable I2C2.

It would be advantageous to develop a location / script which is automatically executed as root upon power-on so that we can (for now) configure the board, for example Enable I2C2.

Eventually, we will want the DAQ application to automatically run upon power-up, so this will be essential for the flying article.

I have successfully run some test initalization scripts, please see the most recent pull request.

As of now, It does no more than stated.

I have verified its functionality through a boot, however please note that I do not manage any possible errors during initialization.

I imagine that I could get the "Enable I2C" script working for the next commit.

The script now searches for and runs "Enable_third_i2c.sh"

However, I recently noticed that this script actually executes during startup AND shutdown which could be bad in its current form. I have started looking into it, but I may have some trouble understanding it.

So, the entire issue was the fact that I had a bad directory call in my init script, for details, see pull request 12.

It should work as intended.

It doesn't handle errors, but is that a concern with init scripts?
