Serial console not working
I have a recent Omega2+ running b160.
I'm connecting to the micro-usb port to my Mac running 10.11.6.
I installed the Silicon Labs CP2102 package, but I don't ever see anything in /dev/tty that resembles the name in the instructions.
Can anyone suggest what might fix the issue?
@Matt-Gessner "micro-usb port" so you have got a Dock too. Please let us know which one.
Somewhere in your arrangement, there has to be a USB-serial dongle (or chip if that's in a specific dock that has it),
such that Omega2's UART (Rx/Tx pins) will go thru that chip to talk to your Mac's USB port.
It's not just load the software CP2102 device driver then the actual physical device: CP2102 (which is a USB to serial interface IC) will show up from the thin air...
BTW, that CP2102 driver needs to be installed on the Mac side.
Hi, and thanks for your responses.
I have an expansion dock. I'm connecting the u-USB port on the expansion dock to my Mac.
I'm not using the UART pins on the dock.
Connection should look like this picture: https://raw.githubusercontent.com/OnionIoT/Onion-Docs/master/Omega2/Documentation/Get-Started/img/unbox-5-omega-switched-on.jpg
The USB-serial IC CP2102's driver for MAC should be here:
This is the same setup I have.
I re-installed the driver from the link you posted, and it still doesn't work. I powered down the Omega2+, disconnected the cable, connected the cable, powered up, and waited until the system was up and running. I still don't have a /dev/tty.* file that goes with that device.
Also, I've tried different USB cables.
Perhaps something is defective.
I've seen instances where one had to reboot to see the device. You've already rebooted your macbook? Is there a system control panel that lists all connected USB devices in Mac OS somewhere? (Not a Mac user myself) Can you show is what it says there?
Well, on the THIRD micro USB cable, I finally have /dev/tty.SLAB_USBtoUART. I haven't rebooted the Mac as it turns out not to be necessary. I'm really surprised it was the cables. They work for other devices.
Thanks to all who replied.
May be several reasons:
very cheap USB cables do not have the signal leads D+ and d-) thus not suitable for data communication purpose
Omage2 is very power demanding. Poor/insufficient power supply/not enough regulation/thin and too long power cable (from that micro USB cable), all causes Omega2+dock not be able to fulfill its job. <-- POWER ISSUES have caused so many heart burns in this forum
