We do not request blocks with a certain number, we only request a file and ack incoming packets. If you look at 'case TFTP_DATA' in tftp_handler(), you'll see tftp_block getting overwritten by the block number of the incoming packet. The initialization of tftp_block is only used for tftp push. For tftp push RFC1350 says that the first packet we send has to have block number one (not zero). > > tftp push isn't working though.

The transfer continues once the timeout handler triggers and the packet is resent.
