I buy a board olinuxino lime 2 and I have tried to boot the system operative with official images with android or linux but nothing happens, the test the voltages but are ok, I tried mount the image with win32diskimagger, dd from linux but nothings happens, i connected the board to my pc by UART and these message are shown:

### ERROR ### Please RESET the board ###
I have tried everything but the board doesn't boot, somebody knows what is my problem?
Maybe try to reflash the MicroSD card, maybe it got corrupted.
Even fsck wouldn't be any help, since u-boot is placed before the first partition.
But it sounds like you tried different images?
You could try what happens when you try http://linux-sunxi.org/FEL/USBBoot, but you need a selfbuilt u-boot for that. USB OTG is the micro USB connector.
It might work to extract u-boot from the card and boot with that:
dd if=/dev/sdX of=card_u-boot-sunxi-with-spl.bin bs=1024 seek=8
sunxi-fel -v uboot card_u-boot-sunxi-with-spl.bin
Expected behavior would be that it fails to boot and gives you a shell. A20 only goes automatically into FEL made if there is neither a card inserted nor NAND bootable. Otherwise we would need to hold the recovery button while powering on your board, it then stays in FEL mode until it gets commands.
LIME2 has 1GB of RAM memory. From your log this doesn't seem the case. Are you sure you are testing with the proper image?

Just make sure to re-download and test again with the latest image suitable for your board. There was a bug in the
previous release a week ago that prevented the SD card from booting.
I downloaded again a20-lime2_mainline_uboot_sunxi_kernel_3.4.103_jessie_NAND_rel_13 and made bootable sd again by dd and still happen this:
I notice that only in the first boot the uart message is (current consumption is higher):

i thought that my lime2 only had 512 ram because i looking for dram datasheet but i realize that it have to have 1GB of RAM, what is the problem with my board? Thanks you for your help!!
Probably there is some hardware problem with your board. If you purchased the board directly from us drop an e-mail at support@olimex.com and link to this thread, we would give you RMA number so you can return the board.
Best regards,
