followed this guidance

https://community.nxp.com/servlet/JiveServlet/download/599835-1-369293/i.MX_Linux_User%27s_Guide.pdf

$ sudo dd if=<image name>.sdcard of=/dev/sdx bs=1M && sync

from the above command i'm trying to copy sd card full image to sd card ..

after this i plugged memory card into imx6 solo board for booting .

to Communicate with hardware using usb cable for ubuntu I'm using here GTKterm as an example but any other debug terminal program can be used.

i wondered by seeing an empty console ???

is there any further procedure for boot up board

Hello Yasoda S,

The steps are correct. However, the default bootloader loaded on the .sdcard image is for the i.MX6D/Q. If you are using the i.MX6Solo you would need to load the corresponding bootloader on the SD card with the following command:

$ sudo dd if=<U-Boot image> of=/dev/sdx bs=1k seek=<offset> conv=fsync

I hope this helps!

Regards,

and There is NO detection of SDcard after doing this, no files are copied

Hello Yasoda S,

Are you copying the bootloader after loading the complete .sdcard image? The .sdcard should create the necessary particions. Afterwards you would need to load the bootloader and you will see no change on the partitions but it should boot on the board.

Also, please make sure that you use the offset necessary for the i.MX6Solo bootloaoder. I see that the command you used is lacking the seek offset and you need to use bs as 1k so the seek works correctly.

$ sudo dd if=<U-Boot image> of=/dev/sdx bs=1k seek=1 conv=fsync

I hope this helps!

Regards,
