Help a newby? Help, I ordered a gumstix, cfstix pack, for Xmas and am = now getting around to it. When I connect the boards, and put power to, = it does absolutely nothing but lite the little green LED. I connected = the supplied serial cable to my PC, ran HyperTerminal, 115200,N,8,1 and = expected to see the sign on message. Tried both serial ports, nothing! = Check with another computer that HyperTerminal was working, it was. = Tried using both a straight cable and a null modem, nothing! Is the unit defective, or what? Thanks in advance |

You do realize the Gumstix serial ports are TTL level unless you have a Tweener? You'll need to figure out a way to do the conversion. I use a "Shifter" board from Sparkfun myself. -marc On 1/17/07, W. Werner <wil...@co...> wrote: > Help a newby? Help, I ordered a gumstix, cfstix pack, for Xmas and am now > getting around to it.

Scratch what I said: you have a Waysmall board in that pack ;) -marc On 1/17/07, Marc Nicholas <gee...@gm...> wrote: > You do realize the Gumstix serial ports are TTL level unless you have a > Tweener? > > You'll need to figure out a way to do the conversion.

Thanks Dave, yes I did. No go. So I enabled and tried all combinations there of . No go. Then I go out my scope and looked at the connector. No activity on any pin, and no voltage on any pin. Think it's broke?

Hi Bill, On 1/18/07, W. Werner <wil...@co...> wrote: > Thanks Dave, yes I did. No go. So I enabled and tried all combinations there > of . No go. Then I go out my scope and looked at the connector. No activity > on any pin, and no voltage on any pin. Think it's broke? First you should make sure that your HyperTerminal is in fact working properly. Also, there are two type of serial cables, a null modem variety and a modem variety. The modem connector normally has a green connector on the end. You want the null modem variety, which should be all the same color. Try disconnecting the serial port from the gusmtix. Let's start at the back of the computer (on th DB-9) connector. You should measure a negative voltage between ground (pin 5) and TxD (pin 3). If you short pins 2 and 3 (on the DB-9 connector), you should be able to type in HyperTerminal and see what you type. If that works, plug in the DB-9 to mini-din8 cable. This page shows the pinouts: http://docswiki.gumstix.com/Gumstix_motherboard_I/O The pin numbers are from the perspective of looking at the waysmall board, Connect pin 3 to pin 5 on mini-DIN connector. You should then be able to type in HyperTerminal and see what you type. Make sure HyperTerminal is configured for 115200 baud, 8 data bits, No parity, 1 stop bit and no flow control. When you power on the the gumstix, you should measure -5 volts (or thereabouts) between Pin 3 and pin 5 on the female DIN connector on the waysmall. If you're not measuring -5 here, then the waysmall is probably bad. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
