Cannot tftp to swith

I have a 3560X 24p sw 15.0.1 se      I tried to load a new image and I cannot get to the TFTP server.

When I look at the IP routes it looks like this. All vlans are created on this switch I can get to all the vlan interfaces however I cannot get to an end device like 172.16.20.104.

It is a universal image which I will look at. Bottom line is I cannot change the image and that is how this all started.  All devices work okay

why do I have a 32 bit entry as well as a 24 bit entry for each vlan.

From your switch, can you ping the TFTP server?

What TFTP application are you using?
