error trying to upload bin file to bootloard on atmega16

[I am somebody]

I'm using a olimex board that has a atmega16 on it. I got board to
talk to my terminal program (I'm using a mac for most of this) but
when I send it a .bin file I get the following error when I try to
xmodem the .bin to it. :

waiting for password.
waiting for data.
CCCCCCCCCCCC
### Send (x) main.bin: NAK on sector
### Send (x) main.bin: Got burst for sector ACK

timeout.

And I've tried the windows dephi app and it doesn't seem to work
either.

ideas?
