    Intel Galileo - a very Unstable board for now


      I just got my intel galileo board today (waiting for windows on devices) and I was very happy but.....


      First problem I encountered was unable to upload sketches through arduino ide even sometimes worked (I updated the firmware, loaded full linux on SD Card). The other problem I encountered is by pressing the reboot button. The Usb Led shuts off and the board stays like this until I power cycle it.


      the error I get is even if the board is correctly reported on COM4

          Call it unstable if you like, but mine has been running 24/7 for months according to "uptime".

          Only computer in my house with that reliability record.


          Reboot does not work on 0.7.5 firmware, it is documented on this forum to not work, and the fix is simple.

          Upgrade the firmware to anything post-0.7.5, like 0,8.0, 0.9.0, or 1.0.0 and reboot works fine.

            Unfinished - yes.

            Lots to tinker with - yes.

            Rough edges - yes.


            Unstable - now that's a grave injustice to the little fella.

              I think the stability depends on the usage model.


              Using it as a Linux box, it is VERY stable. Is there such a thing as an unstable Linux box?


              Using it as an Arduino device, it is not at all stable. I cannot count the number of times that I have had trouble connecting to my Galileo and/;or had trouble downloading sketches onto the Galileo. Compared to other Arduino devices it is very unstable, very frustrating, and even boarders on the verge of even being usable.


              The things I have done to be able to connect and download sketches to my Galileo:

              1. Restarting the IDE and rebooting the Galileo at the same time.
              2. Changing the USB port that is connecting to the Galileo.
              3. Removing the Device Driver for the Galileo, restarting the Galileo, and the Host PC.


              So far, I have found that one of these will work, but it does not seem to be the same fix every time.

              • 4. Re: Intel Galileo - a very Unstable board for now

                I've given up on that entirely.

                Doesn't work the slightest bit.


                However, what *does* work, and reliably too, is not using USB link to download the compiled sketch.


                Rather, assuming that your Galileo is also on the (same) network as your Arduino IDE, you can rewrite the loader script to use SSH to download the sketch and start it.


                This thread Partial solution for Arduino w/eglibc-based Galileo image which is in a slightly different context of making an eglibc Linux image work with the Arduino, contains the (Linux) version of the SSH download script.


                Making this work for Windows is left as an exercise for the reader, but since it also uses an /sh shell, this should be trivial.


                (And agree with your general point: the Linux image is pretty stable, albeit with some non-working parts in the standard Intel image. The Arduino integration could best be described as "unfinished")
