tftp_handler do eth_halt when TFTP_ERROR, but eth_halt will remove eth device if it is an usb network. usbeth's private data will be unaccessable when usb_eth_free_pkt, touch it will trigger data abort.
Next is the console messages:
=> tftp xxx ... Loading: * TFTP error: 'open failed: No such file or directory' (1) Not retrying... data abort pc : [<9feb6ba2>] lr : [<9feb6b9f>]
Fix it.
