Check out http://doolittle.faludi.com/ntpclient/ for a small time client that works with gumstix. Build with make CC=arm-linux-gcc, and run like ./ntpclient -h time.windows.com -s To set you date and time via network. Or use your favorite time server.

I think there's an ntp client (or two) in the buildroot too, but I haven't tried them yet. I'll take a look when I get back if someone files a mantis bug.

I was wondering if anyone has had a situation whereby the gumstix boots but the rs-232 comms is not quite right. By that I mean that most of the characters are correct, but there are a lot of junk characters in the stream as well. I've played around with the registration of the pressure connector quite a lot (Old gumstix) and it doesn't help. In a different harness I have it works fine btw. The one that is giving problems does have about 20cm of ribbon cable before it hits the max 3233 chip (which runs at 3.3V), I'm not sure if that has an influence. - Kim |

Used to happen to me occasionally with an old-style pushdown connector version of the gumstix where I'd abused it pretty badly and the connector pins were a bit bent, and didn't always push down cleanly... I don't think I've seen it since then.

You may have something there. As I desoldered the pressure connector off my waysmall to use with this and just before that stopped working it started to display a behaviour that was much like on this new harness. It doesn't look that abused, but it's very difficult to see if the pins are aligned properly as you can't see through the pcb when it's on and you can't see any test points to check against. Probably there are a couple of pins that bend in the same way to cause this behaviour then :( - Kim > Used to happen to me occasionally with an old-style pushdown connector > version of the gumstix where I'd abused it pretty badly and the > connector pins were a bit bent, and didn't always push down cleanly... > I don't think I've seen it since then. |

> What is it talking too? I hope not Hyperterminal. I have seen this > many times before with the stock Hyperterminal at 115K baud. > David. It is hyperterminal. But it does the same with minicom as well. However, now that you mention it, someone mentioned an improved hyperterminal didn't they. I can try that. The funny thing about the connectors is though, they look totally fine and non-abused. They really are in good shape but no amount of tweaking the position that I hold the board on fixes it :( It's irritating because I can't rule out the connectors. When you hold it against the PCB you can't see the pins any more so I can't see if they are shorting or not. - Kim |

Ah yes. I remembered that afterwards and was meaning to look that up. I'll down load it now. Though, I have big question marks about it, because the exact same gumstix performs fine through hyperterminal when it's connected to a different harness (Though one that doesn't have a jtag connector :( ).

> If you are using a gumstix board, try the other port. Just add the getty entry for > it in inittab. > David. That's not a bad idea. Though a little tricky. I'd either have to load a new kernel into flash, which I'm avoiding until I can have a proven working jtag cable/connector (The reason for this new harness), or boot from the mmc via uboot, which is a chicken egg problem. I'd also have to solder in a second MAX3233 chip to support this operation. But it's an interest avenue to pursue. But actually, the fact that on a different harness it works fine works against this. Apart from the gumstix pressure connector being the culprit, is there a chance that too long a cable for the 3.3V Uart lines can cause this? I have about 20cm of ribbon cable going to the target board. Actually, with another small board in between to rearrange the lines. - Kim |

Hi, I'm using the waysmall. A reboot is in most cases not enough. A power off-on cycle is required changing the configuration. Issueing a reboot and the bluetooth stack remains somewhere... Has soemone successfull spawned a ternimal sesion using bluetooth? Still reading and haven't found...

Is this with the new gumstix or the old one? If it's the old gumstix, then it leaves open the possibility of the connector I suppose. It could possibly be shorting the transmit or receive of one port but not the other. - Kim |

I have. One key thing about serial ports via bluetooth with the 'stix is that I was having trouble getting the getty on the bluetooth serial port on the gumstix to wait forever for a connection -- it seems to just exit after about 10 seconds if no connection attempt is made. So I have a really ugly hacky loop in a shell script which keeps restarting the getty when it dies. The result is that when you try and connect to the bluetooth serial port, you'll get a delay of between 0 and 10 seconds or so (sometime longer -- haven't delved into it) before the login prompt appears. Should work OK though after that. C On Aug 16, 2004, at 5:08 PM, Bouwens / Mehl wrote: > Has soemone successfull spawned a ternimal sesion using bluetooth? > Still reading and haven't found... |

Hi, I suppose the gumstix will not be resetted in a correct manor. At the moment I use a pc with the widcomm bluetooth protocoll stack and the Apple Rendezvous sw. There are cases where the bnep0 device does not get a valid ip address. Rebooting doesn't help in all cases. One out of 5 reboot commands results in a valid ip lease... sometimes the bnep0 device disapears completely. In case of the later, the pc doesn't see anything. Issueing a second and consecutive reboot comands causes garbage to be displayed when going down. Once a while I an error about a stalled bluetooth connection and quite a lot of timeout errors.

Try to disable all non essential bluetooth services started in the init scripts. Be sure to disable them by commenting out the sections as the variables intended for this purpose do not work. Also, be sure to force bt disconnects before you halt. I created a shutdown script to close connections. This was the only way I could halt and get a new lease the next time. David.

I've made some progress on my flakey rs-232 problem. In my case, my gumstix worked fine in one harness, but my new one had the problems. The pressure connector looked fine and there were no shorts in it. I've made a new harness with a really short cable to it and now it works fine. The other one had about 20cm of cable and another board inbetween to rearrange the connections (Because of a mistake). Apparently that's too much length for the raw uart signals. I'm running the new one off 3.7V directly from the battery. It also provides access to the jtag pins so later on I should be able to see whether my home built jtag cable works or not. - Kim |
