Unable to boot a20-olimex-lime using debian sd card image

[embeddedlover20]

I got a new a20-olimex-lime board. On the PCB, it says "a10-olimex-lime" but contains a20 processor without NAND. I downloaded the Debian image from the following link:

A20-OLinuXino-LIME Debian image with Kernel 3.4.90+:
https://drive.google.com/file/d/0B-bAEPML8fwlV0RsenB6cXBqSWM/edit?usp=sharing

I was able to download the image and burn it on a Class 10 SD card using dd. However, I am unable to boot the board using the SD card.

Can anyone give me any idea what may be happening? Any clues or suggestions will help.

I don't own the olimex-lime, so I don't know the fine details of it. On my board I have a green LED that goes on when the bootloader finds a valid image, and starts to blink when debian is completely booted. Does your board also has such a LED?

Does your board requests an ip address from the dhcp server? Can you ping the board?

What was your dd command? Dit you remember to unpack the image before writing? Using dd to write the image on the SD card should work, I have documented it here:
https://www.olimex.com/forum/index.php?topic=3560.0
3) download A20_debian_kernel_3_4_LAN_USBx2_Cards_LCD_HDMI_SATA_TS_X_GPIO_OTG_MIC_Video_accel_release7.7z
https://docs.google.com/file/d/0B-bAEPML8fwlX2tYS2FmNXV5OUU/edit?pli=1

4)write the image to a SD card. I have used a 32GB card, but only 4 GB is used.
$ 7z e A20_debian_kernel_3_4_LAN_USBx2_Cards_LCD_HDMI_SATA_TS_X_GPIO_OTG_MIC_Video_accel_release7.7z
# dd if=A20_debian_kernel_3_4_LAN_USBx2_Cards_LCD_HDMI_SATA_TS_X_GPIO_OTG_MIC_Video_accel_release7.img of=/dev/mmcblk0

5)enable DHCP, so the olimex board can be reached via the network. This can be done by mounting the SD card, and editing /etc/network/interfaces. Uncomment the line "auto eth0"

Please let me know if it worked for you.
Kind regards,
Cedric

Be more prcise when you say "I am unable to boot the board using the SD card."

Did you try antother SD card? I have one old one (Kingston 4GB) which does not boot while all others boot fine.
