    Problem booting from sdCard


      I want to boot edison from sdcard for the limited space in eMMC,and I followed How to boot Edison from an SD card (Linux) .After getting sdCard prepared,and plugging it  in ,when I type

      sudo fdisk -l

      this came out :

      GPT PMBR size mismatch (7634944 != 7634943) will be corrected by w(rite).



      Disk /dev/mmcblk0: 3.7 GiB, 3909091328 bytes, 7634944 sectors

      Units: sectors of 1 * 512 = 512 bytes

      Sector size (logical/physical): 512 bytes / 512 bytes

      I/O size (minimum/optimal): 512 bytes / 512 bytes

      Disklabel type: gpt

      Disk identifier: 21200400-0804-0146-9DCC-A8C51255994F

      /dev/mmcblk0p10      4849664      7634910   1.3G Microsoft basic data



      fdisk: cannot open /dev/mmcblk0rpmb: Input/output error


      I tried to ingnore this ,and finished the setting. But when I reboot the edison ,it got trapped in this loop :

      boot->stuck here->boot->stuck here......

      So I have to boot from eMMC again...

      Any idea what the problem is ?

          Hello kmij261,
          I'll try to help you with this. Usually this guide does not have any issues as it's been tested by several users, my guess is that there might have been an issue on the process or the SD-Card you were using is faulty. So, my suggestion is that you flash your board (using the flashall method https://communities.intel.com/docs/DOC-25154) into a normal state and try the guide again, hopefully with a different SD-Card in order to avoid any issues.
          Let me know how it goes.
