Well... then the first thing to check is whether it is opkg list or grep that segfaults.

You may try without piping:
opkg list >opkg.list
grep ^python opkg.list

A better way to do it, is to use the package.
cd into the dir where you downloaded lede-project
$ mkdir package/libs/libugpio/
$ cd package/libs/libugpio/
$ wget https://dev.openwrt.org/export/35269/packages/libs/libugpio/Makefile
$ cd -
$ make menuconfig
save changes and exit
then build it
$ make -j4

After that, your dependencies shall be resolved.
Remember that you also need to install libugpio on the omega. You can do so by opkg install libugpio

I just noticed this other thread:
https://community.onion.io/topic/2101/from-cross-compiling-for-the-omega-i-cannot-successfully-build-the-gpioread-example

I also got this problem and libugpio is not even listed in LEDE menuconfig under libs, so I assume one has to find it elsewhere.

@Matthias-Nowak Hello. What is the status of your docks?
I really want one, but forgot about this while I waited for my Omega2.

In order to understand what is going on, you should check the serial console during boot.

Strange.
Here is what I guess is happening:

• rootfs is mounted from from your SPI flash.
• your dev tree contains a bug. You even get a warning about that.
  "[ 10.643639] spidev spi32766.1: buggy DT: spidev listed directly in DT"
• the re-init of the SPI driver cause problems

Maybe you can try booting with a different device tree blob (*.dtb file).

You would have to look at the datasheet.
It has 2 serial interfaces.

I assume one of the serial interfaces is for data transfer while the other is for control.
So, if you use serial to USB converters, you should be able to connect both to an USB hub and connect the hub to the onion.

Did you have any luck with this?
I was just thinking about the same.
I don't think it should be too difficult to locate the ENV offset, but it would be nice to know the full flash partitioning layout.
E.g. at which offsets do you find the kernel, etc.

It is not too difficult to figure all this out, but I would prefer if the information were available on the wiki page.

@Samuel-Mathieson
Sorry for the late reply.
I didn't see your post before now.
If you still wonder about this, here is some hints.

The easiest way is to use a solid state relay or a transistor to PWM control the light.
DC LEDS (without any electronics) is the easiest.

For regular AC, you might want to use a current or voltage limiter instead.
This can be done with a MOSFET, a capacitor and a few resistors.

There are many (other) solutions.

Right before I was about to press send, I did a quick search for PWM AC dimmer, which gave me results such as:

I hope this helps.
