@perillamint-. Did you happen to notice that it says your Omega2+ now has only 64KB RAM? I just noticed that. Looks to me like your RAM has come loose and isn't making proper contact with the PCB anymore.

@perillamint-. You sure you didn't mess up the WiFi firmware-partition? I hope you did take backups of more than just mtd0.

@Ken-Conrad said in DIY Onion-Mini-Dock:

I could never suspect you have hand tremors while at your keyboard, your writing is always clear. Maybe don't have that glass of water too near your electronics!

You have no idea how many times I've toppled it over on my keyboard!

@Ken-Conrad said in DIY Onion-Mini-Dock:

In essence, the problem is that the very act of touching a soldering tip to a tiny placed part displaces the part off the board trace or solder pad ... this tool can grip and hold the part in place long enough to solder the first solder point on the part.

This is why I like solder paste + hot air gun so much: I have a nervous-system issue which causes both my hands and fingers to tremor a lot -- sometimes I can't even hold a glass in my hands unless I use both hands -- and I have trouble soldering even regular through-hole components, but with a hot air gun I don't have to be so precise. I can take as long as I want to with applying the solder paste and dropping the component in place, and one doesn't even have to be terribly precise with the paste, either, and, best of all, no need to worry about accidentally pushing components out of place with shaking iron!

@J-Tech I live in Finland and I doubt you do live here. I could send one in the mail, but I have no idea how much it costs to send anything to another country -- never had a reason to do so before.

@Chris-Stratton I do have one and a tube of solder paste. It's a Yihua 898D+ -- pretty cheap and very handy, I just ain't very experienced in the Black Arts of SMD-work (TM) yet! That said, I just soldered another microUSB-connector with it and it went easier this time around. It's just a matter of lack of practice.

Now, I dunno what to do with these three extra PCBs. It's not like I need more than one dock myself..hm.

I got the missing microUSB-connectors yesterday and just soldered one down. I gotta say, they are a bitch to hand-solder! I gotta think of a better way of doing it.

I received my PCBs today and I see that I've made a mistake: the ESD-protection prevents the USB-host port from working right. Removing the resistor and capacitor (or not soldering them in the first place) allows it to work. Leaving those out just means a slightly less protected USB-port, otherwise the board works fine, so I'm not in a hurry to design a fix. I'll do it when I feel like it.

(The microUSB-port is missing, because Chinaman sent me wrong connectors -- they don't match the holes on the PCB. Just gotta wait for the right ones to arrive in the mail.)

@ayhan-uçar Stop spamming in every single thread you can find, you twat

@perillamint-. said in Way to flash U-Boot on Omega 2:

How can I flash u-boot partition? Does someone knows how to do it?

If you use a custom kernel with modified DTB to make the MTD-partitions writeable, you could just use the mtd utility from within the OS.

@György-Farkas said in USB connection without a dock:

@Peter-Feerick
Its USB protector is a 6 lead SOT-23 (like) SMD.

I believe the 6-pin package is called SOT-363.

@T-NT I hear you. Having internal pull-ups/pull-downs is handy. But there's not much one can do about it. Just remember not to use pull-ups/pull-downs on the bootstrap-pins or the Omega2 may not be able to boot.

@T-NT said in GPIO set pull up mode for INPUT?:

So if it can do dirout-high why can it not do dirin-high as well?

Apples and oranges, pull-resistors have absolutely nothing to do with output.

Am I missing something here ?

Yes, the MT7688 doesn't have configurable pull-resistors.

@Ma-Shin DHT22 doesn't use the one-wire protocol, it uses its own, so what you're attempting to do wouldn't work anyways.

@Christopher Aye

@Christopher Did you flash it with sysupgrade -n image.bin or without -n? The -n flag resets all config-files to default

@Sebastian-Nilsson It should work, but the one I have doesn't. It could be, because mine is a Chinese clone, not an original one. That is to say, YMMV.

@Sebastian-Nilsson said in USB boot without serial:

or is there some way to use the TX RX pins on the gpio to get a serial connection

Yes, buy a separate USB TTL-adapter, like e.g. http://www.ebay.com/itm/CP2102-6Pin-USB-2-0-to-TTL-UART-Module-Serial-Converter-STC-Replace-FT232-New-AS-/291933094711 -- be sure it's a CP2102 or CP2104, as those work the best with the Omega2.

@Christopher wifisetup is for the driver used by the official firmware, it doesn't work here. It looks like you compiled the image using my customized sources, which means it should already have a WiFi AP configured; the easiest way of setting it up is if you just connect to the AP, point your web-browser to the omega-whatever.local and configure your WiFi however you like from there.

@Gökhan-Türkeli After re-reading what you've said, I think you're connecting your multimeter in parallel, not series. You can't measure current by connecting it in parallel. I would recommend googling "how to measure current with multimeter" or looking it up on Youtube.
