Problem booting from sdCard

Jump to solution

I want to boot edison from sdcard for the limited space in eMMC,and I followed .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

Device Start End Size Type

/dev/mmcblk0p1 2048 6143 2M Microsoft basic data

/dev/mmcblk0p2 6144 8191 1M Microsoft basic data

/dev/mmcblk0p3 8192 12287 2M Microsoft basic data

/dev/mmcblk0p4 12288 14335 1M Microsoft basic data

/dev/mmcblk0p5 14336 16383 1M Microsoft basic data

/dev/mmcblk0p6 16384 65535 24M Microsoft basic data

/dev/mmcblk0p7 65536 131071 32M Microsoft basic data

/dev/mmcblk0p8 131072 3276799 1.5G Microsoft basic data

/dev/mmcblk0p9 3276800 4849663 768M Microsoft basic data

/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 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.

 

-Peter.
