Looking for some help. I'm trying to download (tftp) a new ios image on my 2503 and after repeated attempts, I continually get a checksum error after each download. I've changed the config-register to 0x2101 so that the flash will switch to Read/Write prior to downloading. I've tried 3 separate ios images from cisco and here's what I get after each download:
t(boot)#copy tftp flash System flash directory: File Length Name/status 1 8133708 c2500-js-l.112-26d.bin [invalid checksum] [8133772 bytes used, 254836 available, 8388608 total] Address or name of remote host [255.255.255.255]? 10.1.1.1 Source file name? c2500-js-l.112-21.bin Destination file name [c2500-js-l.112-21.bin]?
