I'm moving away from a windows development platform and to an Ubuntu 8.04 platform. I"m using minicom along with a USB to Serial converter / Null modem and i'm trying to connect to the gumstix. The serial cable that is connected to the gumstix worked withthe connection to windows and hyper terminal. I think my problem is I have no idea what serial port the USB Serial device is on. With the old 9 pin I had a 25% of getting it right the first time and my odds increased after that. Now I see 64 tty devices. Any Idea which it might be or how to easily tell? I realize this is slightly off topic and I appologize. Thanks, Michael "In the beginner's mind there are many possibilities. In the expert's mind there are few." -Shunryu Suzuki |

I got it working. thanks for your help. Once I knew everything was setup correctly I pulled out the ohm meter and found that my vcc and gnd wire need some attention. ----- Original Message ----- From: "Michael Caughey" <mi...@ca...> To: "General mailing list for gumstix users." <gum...@li...> Sent: Tuesday, December 09, 2008 10:40 PM Subject: Re: [Gumstix-users] connecting via minicom > ok, I restarted my terminal window and reran dmesg and the USB device > messages showed up. lsusb is also now whowing it.

ok, I restarted my terminal window and reran dmesg and the USB device messages showed up. lsusb is also now whowing it. Not just one but from every time I unplugged it and replugged it in. It does register as /dev/ttyUSB0. thanks. Now I still cannot get it to work. I'll have to play around with it a bit more. I never used a USB port under linux before. At this point though I have the settings to 11520 8N1 and /dev/ttyUSB0. Now I cannot remember if I soldered the jumpers from the robostix to the db9 connector (which converts from TTL to RS232) with a built in null modem or not. I tried the connection with and without a null modem and I get nothing. I'm trying to find on the wiki the following two resources: Which pin is pin 1 on the FFUart on the RoboStix. I have the wire mapping from the wiki @ http://docwiki.gumstix.org/Robostix_I/O_pins Come to think about it I recall messing around with the serial port and removing the console from it so I could use the UART for another device. Its been almost 9 months to a year since I messed with this. I don't recall where to check to see if I did that. I do have SSH access to the board. Maybe the whole Serial terminal connection is a mute point. The only reason I'm going to use it is for debugging my applications. I'm new to C/C++ development on embedded devices. the book I read said I needed (or suggested that I have) both ethernet and serial connections. Seems to me Ethernet would do just fine. ----- Original Message ----- From: "Dave Hylands" <dhy...@gm...> To: "General mailing list for gumstix users." <gum...@li...> Sent: Tuesday, December 09, 2008 10:09 PM Subject: Re: [Gumstix-users] connecting via minicom > Hi Michael, > >> I'm moving away from a windows development platform and to an Ubuntu 8.04 >> platform.
