Thanx James,- You are correct.
TFTP transfers use 512 byte-long blocks by default. With 16 bits words the
file size is limited to 65536*512, or 32M. You can adjust Pumpkin to use 1024
byte-long blocks, essentially doubling the transfer capacity for a maximum of
64MB, but I would not recommend this as FTP has always been much faster IMHO,
and you don't have to get both side to agree on the 1024 block size, which I
have had issues with on some devices. ~M

"PumpKIN is an open source, fully functional, free TFTP server and TFTP
client, which implements TFTP according to RFC1350. It also implements
block size option, which allows transfer of files over 32MB, as well as
transfer size and transfer timeout options described in RFC2348 and
RFC2349."
