I for now have a MCIMX6DL-SDP board and it can be booted from eMMC. So, I would like know how to download u-boot.imx image from a TFTP server into RAM and to write from RAM to the eMMC.


Of course, I have already read the "i.MX_Linux_User's_Guide.pdf" document to understand the steps of program the kernel image, but it seems to me that it does not mention how to program u-boot image by using u-boot, or say it doesn't descript "mmc write" to where address for the u-boot. 


Could somebody do me a favor?? And it would be better if you can provide a instruction that is step by step. 


Thank you.
