@Brad-Buskey Right now, Your showweather program is the only project I have loaded. It sure works great! I don't know about you being a newie. Not in my book. Want to add GPS, but not until I get hotspot working. I thought I did, but soon as I shut off radio in radio in router, blank screen on display. Looks like Omega2 will only send data to wireless router. Tried many other fixes. No good. A reason I want hotspot mode is to demo the project at another location like a school. BTW the Moto-G hotspot mode works fine with my Android tablet. Can't find any reference to this subject in the Community. (Except yours) Probably not really mainstream. I guess I'll just wait.
@Ketsayay-Choohirun You are welcome. Probably nothing is wrong with your Omega - probably you have a power problem. Long thin jumper wires with loose connections at the Omega's pins will cause a dip in the power, just as the Omega needs more power (at least .25A at 3.3V) to turn on the Wifi.
You can use your serial connection to follow the boot progress so we can see when in the boot the Omega is halting.
Well, bad news, it broke again. After I rebooted the newly installed b162 running on the Ω2+, the orange light flashed slowly for a few seconds as if booting normally, then turned off. It didn't broadcast any SSID.
I then tried to put it on the small expansion board, same result.
Tried pressing the reset button while turning it on, same result, no light and no SSID.
@Anthony-Kelly You might try unplugging the omega from the dock and putting a small piece of jumper wire between the receive and transmit connectors of the connector the omega sits in (just be careful to get those and not power lines - a 1k resistor would work too, and be more tolerant of mistakes).
With the wire in place whatever you type in a serial terminal should echo back, without it the echo should stop. That would test the USB-serial distinctly from the Omega 2.
Okay now I can compile the firmware with the Codec for SGTL5000 I'm hanging again.
The kernel module is loaded but a cat /proc/asound/cards lists still --- so soundcards --- I'm not really sure but I think I just have a codec installed but no "card". Am I right if I think I need a card driver in build_dir/target-mipsel_24kc_musl/linux-ramips_mt7688/linux-4.4.52/sound/soc/mediatek which 'uses' the codec?
Does anyone know how to get this thing up and running? It's so exhausting...
But they aren't microcontrollers. They are large embedded systems, or in the case of the Arduino, development boards with a lot of power-wasting components on them compared to using the microcontroller in a way that would be sensible for a battery design.
If you look at the topology of the Adafruit design, the power to run 5v loads has to come from first being regulated down to a plausible battery voltage, and then boosted back up. That particular board is made with components that try to support a lot of current through that path, and warns that the upstream supply needs to be quite capable to match what the board can do.
But that kind of regulate and re-boots topology, if done with lower rated components, could easily explain the kind of issues seen here, in that it can impose a bottleneck on how much power can get from the USB input jack to the USB output one. We still don't know what is on the powerdock and how it is configured, but it's not hard to imagine limitations there.
It seems that mine is working. Placed Omega2+ in the socket and booted right up. Reset button works as well I took voltages of the +3.3 and +5.0 rails and right in order. I unfortunately don't have anything I can hook in/up/around at the moment but did have my meter here with.
Put in a ticket for yours and get it replaced! I'm sure it's something simple [or a bad trace] because it's really nothing but a board with expansion to 2.54mm and a regulator. What could go wrong, lol (sorry, not rubbing it in just being honest)
Could fire up a 16 x 4 LCD laying around, but that's serial. Don't need the effort right now. Think I'll find a little magnifier and mount it right above the display, LOL. More later sir .....
