Hello everyone, I am new to the Gumstix platform, so please pardon my ignorance. I have a few questions that will help me get started. I have purchased myself a waysmall computer 200Mhz with Bluetooth. 1. Do I require a serial cable or am I able to use the USB connection to get to the command prompt? 2. If a serial cable is required, then do I require the normal cable or the null modem cable. Thanks for taking time to answer my queries. Devraj -- Devraj Mukherjee (de...@et...)

Hi Everyone, I have had a Gumstix for over a month now and have still been unable to get it up and running. Part of my problem is that I didn't order a serial cable and had one made, however I think the cable I got manufactuered is faulty. I would really appreciate some feedback on the following issues. The green light on my Gumstix/Waysmall comes on and if I connect a USB cable my Windows machine says it found a new USB device. Does that confirm that my Gumstix is in working condition. I just want to ensure that the faulty cable did not stuff the system up. Thanks in advance for any answers. Devraj -- Devraj Mukherjee (de...@et...) Eternity Technologies Pty. Ltd.

Hi Radu, Thanks for that. From the indication of my board, do you think it would still be okay?

Hi Devraj, If the USB is working then your pxa255 is okay. However you will need to test the COM port. Check the cable first using a multimeter, Radu's advice. Since you are on windows you can try out this low level RS232 communicator. http://www.bb-elec.com/product.asp?sku=3DCOMTEST =20 Just select the COM port you are connected to and set the settings as= =20 Baud Rate - 115200 Parity - None Data Bits - 8 Stop Bits - 1 =20 Now if you boot the gumstix it will start showing the boot process. this will test the connection if it works. Do a sanity check that the serial cable is plugged into the port close to the power adapter on the waysmall; plug the serial cable in before you power-on the gumstix or else you may not be able to see the boot process. and cross check the serial cable connections again before you do any of this. bhaskar.

Hi all, I'm planning on starting the creation process of my first and simple robot (not helicopter) and I was wondering if I should consider gumstix for it or should I just go straight with OOPic. Could you also provide the ups and downs of both as well? Thanks a lot. Thiago Jackiw |

This is a rather open-ended/vague question, but one that I had considered in the not too distant past. It depends of course on the level of complexity of your robot, but if you want something simple, definitely go with the OOPIC. It's easy to program, easy to interface, and has a decent amount of I/O and A2D conversion, and the multitasking is really really handy for a lot of robotics projects. If you're looking for a good robot to start of with on the OOPIC, I tried the Mark III oopic sumobot kit from junun (http://www.junun.org/ MarkIII/Store.jsp). The amount of sensors and board I/O on this kit is great to start off with; I have a GPS, compass and two accelerometers on mine, just as an exercise (they don't do anything really useful, but they do things. :P ) If you want a gumstix, you usually want powerful processing, the flexibility of Linux, multitasking and more complex hardware/software interaction. If you're looking for simple, the gumstix may not be what you're looking for, as you pay for the power and flexibility in direct ease of use. The gumstix is not hard by any means, but it is much more difficult to use than an OOPIC. That's my 2c.

It's set up to connect using USB networking out of the box, so if you have usb networking and a DHCP server on your host machine you should be able to ssh straight in to Linux. However, I'd definitely advise a serial cable too. If you manage to break the Linux installation you'll be totally stuck if you don't have a serial cable, you won't be able to connect at all. You need a serial cable to access the bootloader (u-boot), you only get the USB connection once Linux has booted. > 2.

It's the null modem cable you need, the one with the grey end (as opposed to green). I've got both and they were both plugged in, hence my confusion. Seeing Jim's message prompted me to check. Tim |

When my gumstix arrived, my computer wasn't set up to connect to a usb-gadget network device and give an address, which seemed to be the best way to have things connect over usb. I had to log in over the serial port, get the network going so that it was compatible with what I had, and then I could use ssh to get into the gumstix. Now, I only use the serial cable when I need to reload an entire root filesystem from scratch. I am pretty sure that I used the null modem cable to connect up. The naming convention that most people use has a null modem cable being used to connect two computers without a modem (i.e. the lines are flipped in the cable). The regular serial cable (with the green end in the pictures on the gumstix site) is used to connect to a modem. This is similar to a crossover ethernet cable being used to connect two computers and a standard ethernet cable being used to connect a computer to a hub or switch. Thanks, Jim Walters |
