Hi, Can you confirm this is the case for Chestnut: Console mini- USB : ttys2 USB-A: ttys0 OTG mini-USB: ? I was told the OTG mini-USB required a special grounded mini-A USB to mini-B USB(OTG) cable and a powered USB hub to get the USB keyboard and mouse to work. What about USB-A, does it requires a powered USB hub too to connect it to a host? Thanks. -- ======================= Liem Leong |

Hi dtran11, I am trying to ascertain the exact ttyS0, ttyS1, ttyS2 etc looking at the angle from the Gumstix expansion board because I am trying to run a program on the gumstix. I am looking for polling from the host port which I am listening to ttyS0. This is what I believe the host port is set to ttyS0 but then you saying, no, the console port is ttyS0, I believe this is ttyS2. So what the ttyS? on the OTG port? What are you referring to uart1? Console, Host or OTG. Thanks. On 26 October 2010 14:56, dtran11 <dt...@gm...> wrote: > > Can you explain what your end goal is so I can get a better picture what > your > question is?

I don't have a Chestnut board but I do have a summit board. My console port is ttyUSB0. ttyS0 should be your uart1 port. Doesn't make sense for USB-A and OTG to be statically attached to any device name since it depends on what you plug in to them. I believe the max ouput for OTG is 100ma while the USB-Host is 500ma and the devices hooked up must be Hi-speed usb. If not then you must use a hub.

Thanks dran11, You missed my point. The console port is ttyS2 on the expansion board side and if you connect this with a USB-A to mini-B, on the host it will be ttyUSB0. I presumed the Host port on the expansion board is ttyS0, but I need confirmation from Gumstix I never got. I never get any polling from a device I know it works trying to connect to ttyS0. I will try connecting a powered and an unpowered USB hubs and see what happened. I am running a program inside Gumstix not from a host. I tried to open some of Gumstix CadCam drawings, I couldn't.

I am pretty sure ttyS0 is uart1 and the USB host port is from the TI TPS65950 which would be talking to the gumstix via some parrellel io lines I would assume. phoenixdragon wrote: > > Thanks dran11, > > You missed my point.

Hi dtran11, Which is the uart1? The mini-B they called OTG or the console mini-B Console. What is the USB-A Host then?

Can you explain what your end goal is so I can get a better picture what your question is? I think the problem is I don't know what you are asking.

ttyS0 is your UART1 port (GPIO148_TXD1, GPIO151_RXD1). ttyS1 should be your UART2 but I think it might be reserved for the wifi/bluetooth module(not sure). ttyS2 is your UART3 port which is commonly attached to a usb-to-uart on expansion boards labeled "Console" Can I ask what device you have attached to your OTG? The reason I ask is because depending on the device you attach and the driver, it will create a different device name. For example if you attach a CDC Device to the port (assuming your OTG is set to host mode) you will see in /dev a device called "ttyACM0" which you can talk to like a regular serial port. I hope that helps. Please correct me if I am wrong anyone.

I am looking for polling from the host port > which I am listening to ttyS0. This is what I believe the host port is > set to ttyS0 but then you saying, no, the console port is ttyS0, I > believe this is ttyS2. So what the ttyS? on the OTG port? I think here you get confused. The USB port is not a standard serial port, in the way you can't access it using /dev/tty*. The way you access a USB device heavily depends on the type of this device, and thus the driver used to manage it. So what type of USB device are you trying to access (= what is plugged inside the USB host port)? If for example you have plugged a USB to serial converter, you will be able to access it through /dev/ttyUSB*. But if you have plugged in a mass storage, the VFS layer will manage it for you and you will be able to mount the device /dev/sd*. The user is not assumed to make direct access to the USB device in this case (as you have to manage the filesystem in between). Do you see my point here? USB is mainly managed at the kernel level, but it really depends on the class of device used, and thus the subsystem associated with it. > > What are you referring to uart1? Console, Host or OTG. None of the above. If you are using a development board with IO pins, 2 of them should be labelled RXD1 and TXD1 (thus UART1). You can freely use them to communicate with another device. Be careful, those pins use a 1.8V logic without any buffer to protect the OMAP. > > Thanks. Cheers, Florian |

Florian is correct. If you post what your attached device is then we can help you figure how to talk to it. --------- Dat Tran -- View this message in context: http://old.nabble.com/Chestnut-expansion-board-tp30026306p30058474.html Sent from the Gumstix mailing list archive at Nabble.com. |

Thanks dtran11, Why no one from Gumstix would confirm this as they designed the board and they should know? This make sense now, I agreed with you as in the Ubuntu over Overo developer said the Console is ttyS2. I am not connection anything special to OTG, just a powered USB to use the USB keyboard and mouse as suggested by Gumstix. This is working. What is OTG? ttyS0 or ttyS1 I need confirmation, the port marked Host is ttyS0. I will be using OSGI to test the Host port with a turnaround plug(shorting Tx and Rx pins) to confirm it is ttyS0 or whatever, I will know Can Gumstix staff please confirm. Thanks.

I think that people don't know how to answer because your questions really don't make sense. I'm guessing that perhaps you think that USB = serial port. This is most definitely not the case. USB is not a serial port! It doesn't have Rx and Tx pins. If you want access to a serial port you should look on the 40 pin connector. There you will find the Rx and Tx signals that you are looking for. You should be aware though, that these are 1.8V signals. It is not safe to connect them to either standard RS-232 level signals or 5V TTL level signals. In either case you will need to use level converters to safely connect. Steve |

Hi Steve, Thank you, that another good hint to use the 40 pins, I nearly forgot. We have been using a hawkboard and jumped ship due to poor reliability and laborious initialisation setup. With that board we can connect to a USB to serial cable with no problem. Maybe we are not setting the right baud rate with the Gumstix Host port. Didn't you said it set a higher speed? What is the baud rate on the Host port.

Hi Robert, I can see the documentation but I can't open some of the drawings which caused my drawback. Can you please confirm it 8 bits and 1 stop bit with no parity and no handshake. The 480Mb/s ONLY, means I cannot change the baud rate, am I right? Thanks.

Hi, Anyone can help me change the baud rate of the Host port to a more sensible rate of say 115200 8N1 no handshaking. If this can be done, please tell me how. Thanks.

First you must check to see what tty device your USB device created? Look in /dev for anything like ttyUSB* or ttyACM*. Then take a look at this site http://tldp.org/HOWTO/Serial-Programming-HOWTO/ for tutorials on how to program with a serial port. -- View this message in context: http://old.nabble.com/Chestnut-expansion-board-tp30026306p30067976.html Sent from the Gumstix mailing list archive at Nabble.com. |

I don't know why you keep thinking ttyS0 is the USB port. ttyS0 is your UART1 port. If you have a scope try hooking it up to the TX pin of your UART1 and write something to the port. You should see something to prove to you it does not have anything to do with the USB you are talking about. -- View this message in context: http://old.nabble.com/Chestnut-expansion-board-tp30026306p30068316.html Sent from the Gumstix mailing list archive at Nabble.com. |

Hi Steve, Thank you for correcting me. The reason why I keep referring ttyS0 is as the USB port is because it uses a USB-A connector which is labelled Host beside it. The Console port is a mini-B connector and I keep referring as ttyS2. I presumed the OTG port is ttyS1 and it got a mini-B connector. Are you saying the ttyS0 is the UART1 and is not populated is located in the 40-pin the Chestnut expansion board? and the ttyS1 is the UART2 and again is not populated located in the 40-pin? and the ttyS2 is the UART3 and again is not populated located in the 40 pin?

Why is the USB-A port labelled Host has a fixed baud rate of 480Mb/s and is not configurable is beyond my understanding.

Hi Steve, I am certainly confused and should not be talking about ttyS0 port,(I am overworked and under considerable pressure) you are right I connected a USB to a serial converter at USB0 port labelled "Host" on the Chestnut expansion board. At the moment I am expecting 115200 bps 8N1 as in the Console port. It obvious I am not getting any data through because one of your user said it set at 480Mbps. Is there anything I can do to change the baud rate and 8N1 with no handshaking?

Liem, HOST is a USB port. A USB HOST port. For plugging USB devices into. The CONSOLE port is the only one that is configured, out of the box, to act as a peripheral and provide you with a serial console to the gumstix (via your computer). The OTG and HOST ports are NOT for plugging into your computer by default. Robert Vogt IV CEO IOSiX, LLC 2375 Parkwood Ave Ypsilanti, MI 48198 ro...@io...
