Hi all,
Router: 2501
IOS: 9,14(9)
Flash: 4MB
Ram:4MB
Problem: Can't upgrade IOS to any version. (Try 10.3 -
(igs-in-l.103-13.bin) - and it is fulfill the HW config). Show check-sum
error.
I would like to upgrade the IOS for 2501 router using tftp server which
is directly connected to my tftp server (Cross cable), unfortunately, it
was fail. The OS can be downloaded to the flash successfully, but it was
fail in checking checksum. It shown "invalid check-sum". What is the
problem? Thanks!
Regards,
Lithium
