The dhcp and tftp command should take the filepath from the tftp directory and get the tftp directory automatically not the absolute path. So this will try to get the file from /path_to_tftp_folder/srv/tftp/flash.bin and will fail because it can't find it. So you can drop the ${hostname}. Also drop the initialization of ${hostname} above since it is no longer needed.
Should be like this:
dhcp ${loadaddr} ${update_filename}
"setexpr fw_sz ${filesize} / 0x200 ; " /* SD block size */ \"setexpr fw_sz ${fw_sz} ; "
I think you can drop this line since it does not do anything.
