Hi saida

uboot version can be found in i.MX_Linux_Release_Notes.pdf

included in documents L3.14.28_1.0.0_LINUX_DOCS

For modifications one can look at i.MX_6_BSP_Porting_Guide.pdf

Best regards

igor

i downloaded source code and i have done following steps

$ tar xzf u-boot-2014.04.tar.bz

$ cd u-boot

$ make mx6dlsabresd_config (it was showing some nitrogenxl and config for mx6dlsabresd board)

$ dd if=u-boot.imx of=/dev/sdc1 bs=1k seek=1

$sync

I assume you don't want to dd to partition 1 on sdc disk, but /dev/sdc itself, or the offset will be wrong. And if you also have the rootfs on this disk make sure you have enough space for u-boot (and perhaps the environment depending on where you store that) before the rootfs partition starts (e.g. sdc1), start at e.g. 16MiB offset for that.

thank you for reply

when i insert sdcard through usb adapter in /dev/ there are two partions its showing sdc,sdc1 may be i selected wrong one(that is sdc1)

can you give the details of how sdcard should be formated and why the offset is at 1024 bytes address

thank you

sdc is not a partition but the raw disk. The offset is because the partition table will start from 0, so u-boot need to reside after that.

I'd recommend to create a partition for your file system at offset 16MiB from the start of the disk, that way you should also be sure that u-boot don't share a flash erase block with the file system, thus less likely to corrupt u-boot during a power outage for instance.

Use e.g. Gparted for creating the partition for the file system at the right offset, then "dd if=u-boot.imx of=/dev/sdc bs=1k seek=1", and you should be good to go.
