Hi All,
Could anyone help with forcing Geekbox to work with any USB to UART converter? (FTDI, CP210x, Profilic)
After connecting converter to USB port I can find it in system (lsusb command) but unfortunately there is nothing like ttyUSB in /dev/
Other option is forcing to work ttyS2 serial as normal UART - by default configured as debug console.
I'm using Ubuntu OS ROM V160309
Thanks in advance
Cheers

I'm away from my desk for the next month, but I'll try to help. If your desktop is running linux (mine is Ubuntu) you will most likely need to set up udev rules (in /etc/udev/rules.d) for your converter and set proper group/permissions for your user. Windows machines will require drivers. Most converters should work, but pay attention to voltages. I think Geekbox is at 3.3V (not 100% sure of this) and some converters are strictly 5V. I was able to get the serial console up and running on minicom after fiddeling with the settings. I'll try to get my settings posted here when I return next month.

Using Ubuntu 16.04 LTS on my desktop, no special udev rules were required for the official Geekbox usb to ttl converter, but i needed to be a member of the dialout group to access the device. The Minicom 2.7 settings I used when using the official Geekbox usb to ttl converter. Other settings were left at the default. Serial port setup: - Serial device : /dev/ttyUSB0 (this can vary. check "ls /dev" for your device.)
- Bps/Par/Bits : 115200 8N1
- Hardware Flow Control : No
- Software Flow Control : Yes
Terminal settings - Terminal emulation : VT102
- Backspace key sends : BS
The official Geekbox converter is a Prolific device. lsusb
... ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Connections to the converter. Serial connector has 3 pins. Pin 1 is on top, closest to the reboot button. Geekbox Pin/Wire Color/Converter Pin 1/Black/GND 2/Red/TXD 3/Yellow/RXD NOTE: If you primary need for the serial converter is so you can log in via a terminal. Remember that most linux images have an ssh server installed (or can be installed). This will allow you to log into the geekbox over your network from a terminal window on your desktop. |

I'm sure you can catch up in a few weeks. Anyway, thank you very much for this post. |
