Hi all,
I want to verify the version downloaded by tftp before installing it.
I have the file on my workstation:
$ cksum /var/lib/tftpboot/uImage-pcm038
2156276197 2317276 /var/lib/tftpboot/uImage-pcm038
Under my barebox, I then try to verify the file:
barebox:/ crc32
Usage: crc32 [OPTION] [AREA]
Calculate a crc32 checksum of a memory area
Options:
-f <file> Use file instead of memory
-v <crc> Verfify
barebox:/ crc32 -f uImage-pcm038 -v 2156276197 0+2317276
CRC32 for uImage-pcm038 0x00000000 ... 0x00235bdb ==> 0xd484eccb != 0x808629e5 ** ERROR **
barebox:/ crc32 -f uImage-pcm038
CRC32 for uImage-pcm038 0x00000000 ... 0x00235bdb ==> 0xd484eccb
I have barebox-2010.11.0
How can I use crc32 to verify the files I transfer?
Regards,
Ben
