Hi, Thank you very much Denk for your response. I have already solved the problem today.I used the source code from Uboot source(image.h and crc32.c) and create my own code though I modified crc32.c It is working well.My code tests for ARM cpu and linux kernel image. I am giving my sample test result.
[suhas@l5ac197 Imagecheck]$ gcc -o ucheck Sample.c [suhas@l5ac197 Imagecheck]$ ./ucheck uImage
-----Kernel Image Information--------- Correct Magic Number-- crc check is OK Kernel Image Type=2 Correct image type!! Cpu Arch=2 Correct cpu architecture type!! OS type=5 Correct os type!! Compression Type=1 Correct compression type!! ---------------------------------- <Check Pass> [suhas@l5ac197 Imagecheck]$ ./ucheck uImage2
-----Kernel Image Information--------- Correct Magic Number-- crc is OK Kernel Image Type=2 Correct image type!! Cpu Arch=7 Bad architecture type
OS type=5 Correct os type!! Compression Type=1 Correct compression type!! ---------------------------------- <Check Fail> [suhas@l5ac197 Imagecheck]$ ./ucheck uImage3
-----Kernel Image Information--------- Correct Magic Number-- crc is OK Kernel Image Type=2 Correct image type!! Cpu Arch=7 Bad architecture type
OS type=5 Correct os type!! Compression Type=1 Correct compression type!! ---------------------------------- [suhas@l5ac197 Imagecheck]$ ./ucheck uImage3bad
-----Kernel Image Information--------- Bad magic number--
Bad header crc
Kernel Image Type=133 Bad image type
Cpu Arch=184 Bad architecture type
OS type=34 Bad os type
Compression Type=180 Bad compression type ---------------------------------- <Check Fail> [suhas@l5ac197 Imagecheck]$ ./ucheck uImagebad
-----Kernel Image Information--------- Bad magic number--
Bad header crc
Kernel Image Type=146 Bad image type
Cpu Arch=178 Bad architecture type
OS type=19 Bad os type
Compression Type=121 Bad compression type ---------------------------------- <Check Fail>
*Note: for uImagebad and uImage3bad I have deleted some data and then save it.
Thanking you again WITH REGARDS Suhas Ghosh
