Hi,<br>Thank you very much Daniel for your information.<br>But My requirement is quite different.I know the use if iminfo and mkimage but I can not use those commands. Actually I have to test the Uboot kernel Image(checking of crc and other many other fields) from my fedora 5 through a c program in which kernel image file need to be passed as command line argument.I can use the header files of Uboot source code like image.h and common.h and also the c code of Uboot source but I have to write my own program and need to compile using gcc.<br>I am trying with the source of mkimage.c but I want also the source of <br>iminfo but I can not find it.<br>Hope my problem is now clear. Want valuable information and advice from <br>you.<br>Thanking you in advance.<br> Suhas<p>
