Hi All, I am successfully able to get the U-boot prompt on my board based on IMX27ads.
However I am facing the following issue. Please help me out : I want to load the Linux Kernel Zimage on to RAM. As per the documentation we have used the following command to load zImage using Kermit protocol. " U-boot-v2> loadb -c zImage " (Also tried " U-boot-v2> loadb -f zImage ") Which successfully downloads zimage to the file with default offset set as 0x00000000..... a) But I am not able to understand to which location in RAM this image is written to? b) Please let me know how exactly to load kernel image to specific location on RAM? c) Also how we can change the default location since the user is not given an option to mention the address. d) How to load the file " zImage" to RAM? I was intending to do the following steps : >> loadb 0x100000 zimage >> loadb 0x1000000 ramdisk.gz >> bootm 0x100000 0x1000000 Please help me out as I am using U-boot-V2 for the first time. I am attaching the loadb.c file which I am using currently. Are there any patches Waiting for your responses.

You can compile such a toolchain yourself easily with ptxdist, look here for the details: http://www.pengutronix.de/oselas/toolchain/index_en.html rsc -- Dipl.-Ing.
