I have a Yocto build running on an Overo Air, and I'm having weird problems with the serial getty service. Sometimes when I boot the Gumstix, the serial getty service just keeps starting and stopping over and over again until it eventually stays started and prints the login prompt. Other times it stays started the first time and prints the login prompt right away. I haven't been able to figure out the cause of this as it seems to happen randomly. It is also not consistent how many times the service stops and starts until it finally works. It seems to happen more often when the serial getty service is started towards the end of the boot, but I don't know if that has anything to do with the problem. Has anyone had similar issues with the serial getty service? This is the end of the systemd output (it started and stopped many more times than shown here): Starting Serial Getty on ttyO2...

I am having similar problems. I used the following build http://cumulus.gumstix.org/images/angstrom/developer/yocto/ I am following the steps for establishing a serial connection via kermit as outlined her http://gumstix.org/connect-to-my-gumstix-system.html I power on the board in step-5 and i get no boot messages nothing. Some leds on the gumstix and the tobi are flashing though On Thu, Jan 17, 2013 at 12:53 AM, Ryan <rya...@ut...> wrote: > I have a Yocto build running on an Overo Air, and I'm having weird problems > with the serial getty service.

Update- Changed serial cable. Was using a cheap 1$ cable. Works now. Able to login as root On Thu, Jan 17, 2013 at 10:55 AM, Srinath M <sri...@gm...> wrote: > I am having similar problems.
