I am upgrading the IOS (12.2 code) on a cisco 2503. I got the "invalid checksum" every time when I finished the download.
The router has 16M flash as displayed below:

r2-2503(boot)#sh flash

System flash directory:
File Length Name/status
1 16505800 c2500-jk8os-l.122-1d.bin [invalid checksum]
[16505864 bytes used, 271352 available, 16777216 total]
16384K bytes of processor board System flash (Read/Write)

I have used different TFTP servers for the upgrade. If I only upgraded the IOS which was less than 8 M, there was no problem.

I can not upgrade the code bigger than 8M at all, even some of the IOS are 14M or 13M. Can someone help?

Thanks.
