So this used to work verbatim. the second ampersand is b/c the python script never returns so i would like to Omega LED to stop flashing and finish the boot sequence. Also, the device is used as an AVR Programmer using AVR dude (from the arduino dock 2 package with a modified avrdude config file), so the device shouldn't be powered on longer than a single day. I could possibly remove the ampersand from the setup line.

I removed the setup shell and replaced it with the gpiomux commands directly and that seem to correct my issues

also the python pyGPIO module has a bug in it that I can't spend time trying to address ATM. So i just worked around it.

so i'm trying to do 2 things with my omega on boot, set gpio mux and then run a python script that is to run for the lifetime of the device.

my rc.local script contains the following:

# the system init finished. By default this file does nothing.

# setup the gpio mux
sh /root/setup.sh >> /tmp/setup.log 2>&1


# run the main program
python /root/Flash.py >> /tmp/flash.log 2>&1 &

exit 0

the setup script is

omega2-ctrl gpiomux set i2c gpio
omega2-ctrl gpiomux set i2s gpio

and the python script is:

import onionGpio
import time
import subprocess
import os
import sys

gpio5 = onionGpio.OnionGpio(5)

gpio5.setInputDirection()



print 'Ready'
while 1==1:
	#print 'GPIO5 set to: %s'%(value)
	if int(gpio5.getValue()) == 0:
		print 'starting flash'
		
		os.system("gpioctl dirout-low 4")
		
		os.system("sh /usr/UserFolder/ShellScript.sh")
		
		os.system("gpioctl dirout-high 4")
		
		print 'finish flashing'
#		time.sleep(5)
		
	else:
		time.sleep(.05)
	

these 2 scripts are not running. I can verify this by getting the gpio mux after boot and see that they are still the default, not my changes. They have been granted execute permissions and work flawlessly when ran individually from the shell. What am i missing?

i'm trying to use the omega as an ICSP like how you can use the arduino dock to flash the co-processor installed. I have a warehouse of chips to flash with firmware and eeprom and noticed that the omega would use AVRDude to push the sketch from the arduino IDE. I was wondering if it was possible to use this same concept put push a loaded hex file on the omega to an external avr chip. Could i use the expansion doc or arduino doc or do i need to use breadboard doc to get expose the correct pins.

I suppose i can use uart 2, do i just connect the tx on the omega to the MOSI on the target avr and the uart RX on to the target MISO? would this work and just invoke avr dude via shell file?

Hey all,

So I'm about to get an onion omega 2 + and started setting up my environment using this guide. I was thinking about using .net standard or .net core to make a wrapper for the onion omega 2 +. After sifting through the docs and source on Github, I'm a little lost as to where to start. Basically I'm trying to figure out what the core dependencies are and what needs exposure.

Any direction from someone with a bit more exposure to the API is welcomed and greatly appreciated.

Re: C# / Mono / .NET on Omega?

Has anyone tried to get .net core to run on this yet?
