Omega 2+ USB Firmware Install after Brick. [Resolved]
-
This sounds like what I need to do. I don't understand where you'll see "option #2" though? Maybe I need to research how to connect via USB to Serial but if you power it on with the reset button down, there must me some steps that will give you options on your screen. Am I missing something?
-
@Marty-Mickelson Yes, you need to be able to see what the Omega2 spits out on uart0. If you have reset-button down, or connected to 3.3V with a wire, the boot-loader will present you with a menu for 40 seconds, where you can choose an option for flashing from a USB-drive and such.
-
Ok. I will search the web for how to do that with my Mac. I'm connected from my Mac USB to the dock mini USB port. If you know the url of a resource on the web, I'd love to hear it.
Currently, when I turn it on while holding down reset, the amber light blinks rapidly for 30 seconds, then goes dark. I'm guessing this is the period where it would be asking to reset.
-
@Marty-Mickelson I ain't got a single Apple-device or any experience with OSX, so I can't help you there.

Ah so that is probably how you access "safe mode" etc.
So without any docks but dozens of Prolific PL2303HX USB to TTL adapters is it simply hook one up to RX0 and RX1 or the USB pins (D+ and D-) and then ensuring the drivers are available?

As for using a USB-to-TTL adapter, you need to hook the adapter's RX to Omega2's TX and adapter's TX to Omega2's RX. You do not connect them to the USB-pins.
How the u-boot menu looks like:

@WereCatf I have a linux laptop, but not a USB to TTL adapter. Maybe I'm screwed until I can get one.
-
@Marty-Mickelson Take a look at https://docs.onion.io/omega2-docs/connecting-to-the-omega-terminal.html#connecting-via-serial-mac
-
@WereCatf thanks for the info. May I ask what are the 2 USB pins for on the Omega?
-
@Costas-Costas For connecting USB-devices to it. You know, there is a full-size USB-port on the docks -- its data-lines are connected to those pins.
-
I installled the driver linked to from https://docs.onion.io/omega2-docs/connecting-to-the-omega-terminal.html#connecting-via-serial-mac, but the device never showed up when using ls tty.*. Either the driver didn't install correctly or my Omega2+ is really dead.
-
Marty,
Try ls /dev/tty*, does that work? Also, what dock are you using? If expansion or mini dock it should be there, if you're on arduino or power the USB-Serial connection won't work.Here's my adventure with un-bricking my device using the arduino dock for reference:
http://community.onion.io/topic/1377/might-have-bricked-my-omega2-can-t-connect-via-serial/8
edit: try restarting your computer also, I think I had to do that before the driver worked.
-
@cusackph When I use ls /dev/tty* and I get a lot more items (expected).
I'm using the expansion dock, powered from the USB cable attached to my computer.
I restarted but still no luck.Well done documenting your steps in the un-bricking adventure. I've ordered the USB adapter and will push forward when it arrives.
-
@Marty-Mickelson With the expansion dock plugged in and the omega2+ running, could you take a screenshot or copy the output when you run the ls /dev/tty* command? Maybe the Omega2 is showing up as something unexpected.
-
The output is the same when the dock is unplugged vs plugged in and lights flashing, during the 30 sec it flashes after turning it on with the reset button pressed. I copied the list and diff'd it to make sure. Here's what I get though:

Home now, I checked and with the power switch flipped to off on my mini dock, plugging it into my laptop via the microusb port (NOT the full size port) I can get the correct serial port to show up when I run ls /dev/tty* The expansion dock should function the same way.
I'd try installing the driver again and see what happens, or maybe a different microusb cable. They're rare but I have a cable that doesn't transmit data, drove me nuts when I was trying to put some stuff on an old kindle.
-
I try to power up (connected to the serial) while holding the reset. but the Onion 2 just tries to boot. never noticing that the reset was pressed. Is there another way to do the reset button? Maybe my mini-doc is defective?
-
@Brian-Wharton32 My mini dock also does not recognize the reset button hold. I had to use an arduino dock 2 and a usb-serial adapter to re-flash a bricked unit. I submitted a ticket but havnen't heard back yet. Especially for the mini dock, the usb-serial connection should work as it doesn't do much else compared to the other docks.
-
@cusackph I have the same problems with the Mini docks. - If the reset button or the USB -> Omega2 UART-to-serial bi-directional connection works for you with a Mini Dock, ie Putty shows any keyboard entries, then I am keen to learn how you are doing this!
https://community.onion.io/topic/1451I have isolated my Mini Dock RXO problem to the Mini Dock's on-board UART not communicating with my Omega2s, the same docks work fine with an Omega1. Also sans dock, a direct serial connection via a USB to serial adapter (HAOYU) to the same Omega2s work fine.
