I found a workaround for my serial connection, just put the microcontroller in deep sleep before trying to awake Omega, this is enough to let it boot correctly. Will not be opening a new thread with that.
Thanks

Well, you are correct, the extra heat seems to be because of the ams1117. I already had another mp1584 providing 3.3V to the same circuit, I just add a FET to switch it to omega to power on and now I'm under 50 degrees Celcius.
My problem now is that I found out that omega cannot have anything connected to TX1 while booting, will open another thread to get some help on that.
Thanks for the help.

Hi, I made my own dock circuit, and I'm powering it with an AMS1117, it works well, but it gets hot.
When using the expansion dock, the case of Omega2+ hits 43 degrees Celcius, but in my own circuit, it goes to 53 degrees.
Would the regulator be the reason for the heating up?
Any other detail that I may be missing on my design that is making it to get the extra 10 degrees?
Attached is the relevant circuit.

Hello, anybody had lucky on getting different sizes of oled to work with the available libraries, like oled-exp or pyOledExp?

@Lazar-Demin Thank you for the reply, I will make my own board with the LTE module and a usb hub in between them, add some sensors and a MPPT solar charger as well. Thank you

@bill Yes sir, I used this one: http://downloads.openwrt.org/releases/19.07.6/targets/ar71xx/generic/openwrt-19.07.6-ar71xx-generic-onion-omega-squashfs-sysupgrade.bin
It has been running, it's not on all the time, but every time that I connect I runs perfectly.
Before upgrading I had remove the Onion interface and added Luci, even did the upgrade thru the web interface.

Looking at the schematics I don't see anything between CPU and LTE module, so that answer my question. I will have to build my own module then.

Hello @jossvall, I didn’t doubt that the CPU offers, but the board doesn’t seems to, my guess is that the port is been used by the LTE module incorporated. If that is the case my solution would be making my own pcb adding a hub between CPU and LTE module, so I can add more devices.
Thanks for the input.

Thank you. The idea is to remote to a device over Serial, so this v1 board did the trick. But I'm looking in upgrading this, using the Omega2 LTE, but I was looking at the specs and it doesn't seems to offer the USB Host port, it's been used by the LTE module?

Thank you guys for the reply, I manage to update the firmware to 19.07.6 and then all package installation worked fine thru opkg. I have now a Omega 1 running with OpenVPN client, ser2net and 4G dongle.
Regards

In any case, I can't seem to find any information about crosscompiling for V1

Hello, I have a Omega V1 running Chaos Calmer, and while trying to install some packages I'm getting:

• satisfy_dependencies_for: Cannot satisfy the following dependencies for openvpn-openssl:
  *kernel (= 3.18.23-1-b2f200610f46d20ef52d269421369d0c) *
  I'm running Linux Omega-1468 3.18.36
  What should I do here, compile the package for this kernel, or recompile the image with the module included?

@Janus-Sanders I did try insmod "module", but the command console doesn't come back anymore, stop responding, and after a few tries I bricked the Onion. Just waiting to solve this brick problem to come back to the modules issue.

@Lazar-Demin Hi, my second Omega is on shipping right now, I will try as soon as I receive. But with chip is used in your ethernet expansion, any chance that I could use a enc28j60 based ethernet module as a eth expansion?

I'm trying to install some modules from a differente kernel 3.18.20. Ok, I can get to uboot, but I don't have a ethernet expansion. Any way to flash it by serial?

ok, new kind of dead: led do not stop blinking, ever, serial doesn't show much, doesn't let type, reset button and long reset doesn't respond. Ideas?

And stuck again. I have 5 modules on /lib/modules/3.18.20 that appears after I installed the usbip packages, and I can't figure out how to load them on the kernel.

@Kit-Bishop Solved, thanks

@Kit-Bishop Thank you, the first option of hard reboot worked, back to action.
