    Arduino/Gen2 com. issues


      This is ridiculous, I am trying the third Gen2 board and the board/Arduino still not communicating properly.

      First two got bricked when trying to update fwr, I followed the start-up guideline to the letter including the latest Arduino rev, it got stuck in Step4.2-Go to Help -> Firmware Update - nothing happens, after >1hr waiting tried to kill the Arduino app. on the PC which bricked both of them (USB driver was worthless after that).


      On the 3rd unit, I decided to try loading the Blink file command before going to step4, so now its stuck in "Uploading"

      Here are the messages:

      Any suggestions ? I'm running out of ideas

          Hello pdx4s,


          Are you sure you are following this guide? If so make sure you're using the correct power supply (2A @ 7v-12v), always remember to connect the power supply before the USB port otherwise it could result in damage to your Galileo. Something that could be causing your issue might be a corrupted file on the download or decompressing, so make sure you download the latest software for your Galileo in here.

            That issue usually happens when you select the wrong com port. Make sure you are using the correct com port.

            Also try rebooting or alternatively, go to task manager and kill the bash.exe and lsz processes.


            Also do you have access to the console of the Gen2? Does it boot fine?

            • 3. Re: Arduino/Gen2 com. issues

              hmmm.."when everything fails read the manual" ?

              well folks I could use a bit more credit than that, of course I use the start-up guide, and yes the correct ports/device were selected,


              Anyway, I didn't had a chance to post that evening but after placing the original note I made few more trials:

              1. installed the drivers on another PC (tablet PC with only one USB port) and for my surprise all went fine, including Blink, didn't tried yet fwr update check command as I'm still afraid of possible getting it bricked but this was a major improvement;

              2. went back to my desktop and tried another USB port, same issue, when I connected it to the third USB port, it detected it as COM5 and Bingo it worked same as in step 1.

              Conclusion: not all USB ports are the same or the Gen2 USB driver is not quite plug-n-play as advertised. My take its a little of both, marginalities are usually the cause to similar issues, I don't have an issue with any other device using the same ports that didn't worked with the Gen2. Also I wonder if there isn't a collision some where between the com ports/IRQ ?


              BTW, the BKM I hear from some users is that they don't rush to follow the start-up steps due to concerns with the fwr update step. May need to get more folks to say why.

              Now I have another issue IDE app. doesn't open on the screen, it just had the developer page for few sec's and then nothing, trying to reboot.

                Hello pdx4s,


                I can see from the picture you attached before that you are using Windows 7, some other users have had the same issue, the window shows for a sec and disappears soon. In the link below you will find a post where this issue is already resolved. Please let us know if this resolves your issue.

                If you have any more doubts, don't hesitate to ask.

                  Hi pdx4s


                  Were you able to communicate your Galileo Board with your IDE?
