Clone eMMC for replication Apalis imx6

Hi,

I am working with an Eagle board from Diamond Systems which has an Apalis imx6 carrier board. I would like to make an image of the system with the code running on it for replication purposes.

I have had a look at this article “how to clone embedded linux on emmc based toradex modules” and have had no luck from step 1 “Activate UMS feature”

Apalis iMX6 # ums 0 mmc 0                                                       
UMS: disk start sector: 0x0, count: 0x760000                                    
g_dnl_register: failed!, error: -19                                             
ERROR: g_dnl_register failed                                                    
at common/cmd_usb_mass_storage.c:107/do_usb_mass_storage()                      
Apalis iMX6 #

Since that did not work, I then tried to use the dd command with the source being /dev/mmcblk0 and output to the sd card /dev/mmcblk1. Copying seemed to work but flashing it to a second board with run setupdate didn’t.

How can I make an image of my system for replication purposes?

I would be grateful for any help.

Best regards,

Jennifer

HI Jennifer

Thanks for the Information. Which OS are you using on your host?
Did you connect the OTG cable to your carrier board?
How did you connect the carrier Board to your Host?

Best regards,
Jaski

Hi Jaski,

The OS is Angstrom. I use SSH to connect from my PC to the board.
This is the link to the description of the Eagle Board

Best regards,

Jennifer

All good now. Many thanks!

Hi Jennifer

Thanks for the Link. You need to connect a USB cable between the Eagle Carrier Board and put it to peripheral mode as explained in the section 11.5 of the Manual of the Eagle Carrier Baord. This should make ums 0 mmc 0 work in U-Boot.

Best regards,
Jaski

Perfect that it works. Thanks for the feedback.
