Catalyst 3750 not booting

I have TFTP'd the bin file from my PC into flash...i did a boot system flash:Image name.bin, write memory and reload...when the switch reloads it loads about half of the image and then says error loading image and i get the switch: prompt...if i do a dir flash: the image is there...thinking it was a bad imagine i redownloaded and retransfered the file..still same thing..i checked the md5 checksum and the image is fine...any ideas?

Does the switch have sufficient memory to run the new image?

Re: Catalyst 3750 not booting

a dir flash results in

seeing

c3750-ipservices-mz.122-25.SEB2.bin (the one im trying to boot)

c3750-ipservices-mz.122-25.SEB4 (this is the directory for the bin file)

i have tried booting the SEB2.bin file from the switch: prompt and i get the same thing....you can see it loading...it gets about half loaded and then it stops and says error loading file flash:c3750-ipservices-mz.122-25.SEB2.bin

any ideas? TIA

Re: Catalyst 3750 not booting

Is there anyway you can copy and paste the message from the console when it was booting up?

Re: Catalyst 3750 not booting

I had the same problem, it turned out to be a bug in the version of code I was using.
