    SD card not mounted after boot

      Hello,

      My system is the Intel Joule x570 with the Expansion Board and an installed ubuntu 16.04, provided by intel (version 4.4.0-1000-joule).

      The problem is, that after booting, the inserted SD card is not mounted automatically. Taking a first glance at the kernel log, it seems that the following error might be the crucial one: mmc0: error -110 whilst initialising SD card.

       

      The error occurs regardless of the used SD card. Also checking the sd card (using fsck) on a different computer and inserting them right before boot did fix the problem.

       

      Is there any fix or workaround for this problem? Thanks in advance for any help.

       

      Regards,

      Niels

       

       

       

      A short abstract of the kernel log. The full kernel log is attached to this post, too.

          Hi niels_p,

           

          Thanks for your interest in the Intel Joule Platform.

           

          I'm sorry to hear that you are having problems with your SD card. Now I have a couple of questions, before we start looking for a solution to your issue:

           

          1) Was your issue solved when you use the command fsck?
          2) Which guide did you follow? I would recommend to follow this guide Intel Joule | Developer , also check this thread Re: Installing Ubuntu on Intel Joule 570x  and follow the recommendations given by the users.

           

          I will be waiting for your reply, have a nice day!

           

          Best Regards,
          -Jose.

            Hello Jose,

             

            (1) I ran fsck before and after rebooting and it did not mention any error. However, the error 'Volume was not properly unmounted. Some data may be corrupt. Please run fsck' still can be found the kernel log.

             

            (2) I followed the instructions for 'Alternative install: Ubuntu Desktop 16.04 LTS'. Apart from the SD card issue, the system runs as expected.

             

            I just found a related topic, where the same issue was mentioned: Ubuntu/Other Linux distros not properly recognising external SD?

            To me, the problem described by McCool is the same I encounter. Unfortunately, no solution was given.

              Hi niels_p,

               

              Reading through the thread Ubuntu/Other Linux distros not properly recognising external SD? , I see that this is an issue with Ubuntu not of the Intel Joule, I would encourage you to contact the Ubuntu Community, they might be able to better assist with this issue.

               

              Ubuntu Community: https://developer.ubuntu.com/en/community/

               

              Also, I saw McCool posts and he said that there is a workaround to this issue: "However, the SD card is just not recognized at boot.  If I pop it out and push it back in, it is however recognized and mounted". Additionally, he recommends to use the command lsblk like this: "Then you can clearly see this behaviour (reboot, run lsblk... no card..., then pop the card out and push it back it, run lsblk... there it is!)".

               

              Hope you find this information useful, have a nice day!
               
              Best Regards,
              -Jose P.

                Dear Jose,

                 

                after purchasing a further Intel Joule, installing the latest BIOS (FW 1H3) together with the Ref-OS-IoT version 1705, the very same error is still valid.

                That is, after boot procedure, SD cards are not mounted and the error in the syslog still is mmc0: error -110 whilst initialising SD card.

                 

                Only by popping the card out and in again, the card can be used, which is clearly no solution at all, if the joule is for example covered.

                 

                Furthermore, the issue is clearly not limited to Ubuntu.

                 

                 

                Regards,

                Niels

                  Hi Niels,

                  That's weird, I just tested it in my Joule and it detects the SD card in /dev/ after the reboot. Just to be sure, have you test it with different SD cards?

                  Could you also provide us the "dmesg" file to check it?

                  We will be waiting for your reply.

                  Have a nice day.
