@Daniel-Andrade It's an excellent idea to have the Omega pins available for customized use, and on standard headers to boot.

Dear guest! I understand your frustration. User's editing skills varies from people to people. However, some people just don't care and only want their own little problem fixed quickly and free, i.e. with little or no effort from the original poster. This kind of behavior is not very appreciated among the community. The advice is: show you are genuine, put some effort to learn, get your hands dirty, and help the helpers help you.

Just like racing cars, fast engines rely on quality fuel. Slower microcontrollers are more flexible regarding their power supply input, but there are still limits in order for their internal timings to be met. When push comes to shove, manufacturers decide to provide their own power regulators, but they need to compromise on size, and boards become much bigger than the Omega(2)(+).

A few of us have been living in Shenzhen, China for the last few weeks overseeing the manufacturing of the Omega2 and planning the logistics of actually shipping them out.

Wow! That's serious commitment (and the only way to go to insure Quality Assurance). I'm very impressed by Team Onion!

The way the switch is attached to your fridge looks like an explosive device. There is no way I will close that fridge door ... ever! LOL!!!

@Costas-Costas The & at the end of a command is a request to run the command immediately in parallel (here, parallel to the boot process). This is the perfect technique for very long user made projects or script that runs continuously.

It's a bad idea to use & at the end of a sleep command line because it will run in parallel, thus having no effect at all on your boot process.

@Costas-Costas Any error reported in the system log files? Absolute paths to commands are needed in a system file. Maybe some of the needed system components are not fully loaded when you perform your request. Some people have added a sleep command in the script to give the system a better chance.

@nardev Is this what you are referring?

For those who understand better visually, here is an example of the Linux mount command:

Before the mount, partition B is invisible

After the mount of partition B onto the home directory

IMPORTANT: Note that the original content in the home directory before the mount command disappears until the partition B is unmounted by the umount command.

Read this document for further details about the Linux file system. It's very informative!

@Manuel-Godinez If you are not the type of person that go on a hunt for the bit & piece of information here and there, I recommend that you wait for the PROJECT BOOK announcement, so your mind is kept sane, and your Omega2 kept safe from permanent damages.

Hello!
I would like to know if the Omega2 LTE supports Videotron, a big wireless provider in Quebec, Canada. From, their support, I'm told:

• LTE devices must support Band IV (1700 MHz) in LTE, as well as Band II or V in HSPA (850 MHz/1900 MHz)
• Non LTE devices must support 1700 MHz / 2100 MHz in HSPA (3G/GSM)

I just downloaded the Omega2 Project Book that was part of my Kickstarter order. From a quick overlook ... Wow! Lots of content! Hard work! Very beautifully made! Thanks a lot to the Onion Team!

@Costas-Costas , if you launch your script from /etc/rc.local using &, /etc/rc.local will eventually terminate by itself. You just need to have a long enough sleep command inside your script.

I have the two little holes in the golden metal strips too, but no solder as you do. Btw, your photos are really sharp for the size! Nicely done!

There's a component soldered sideways near the SD card connector edge, the edge opposite to the card entrance. Not sure if it's connected or not because it's darker there.

Use the first Serial Port to help debug.

This is not a problem. This is by design to protect the GPIOs. The docs provide LED use examples here:
https://docs.onion.io/omega2-docs/expansion-dock.html
and
https://docs.onion.io/omega2-docs/using-gpios.html

PS: I'll admit that the expled command should be more intelligent, and ask the user to switch the GPIO LED pins to OUTPUT if it notices they are in INPUT mode (and the WARNING about switching to OUTPUT mode too, especially for cases where the Expansion Dock is not used).

Is this the kind a plastic that can cause static charges if rubbed against another material? If so, it's very dangerous for the CPU's life expectancy should a static discharge occur.

Well, now split in two threads... a merge would be nice.

@Zheng-Han said in Losing Data after power off:

Another possible cause I can think of is you tried to install the packages before your omega2 has fully initialized. Try making sure the orange led stopped flashing after boot.

Perhaps that the return to the COMMAND LINE should be delayed to prevent the problem from occurring.
