The busybox version is 1.15.3, and the following URLs are log images. The first is about tftpd32 log message from windows. http://i.imgur.com/dXYTNpW.png
The second is about wireshark log message from windows. http://i.imgur.com/Tf8KKFy.png It looks like missing Block 407, and I have some questions: 1. The tftpd32 shows 'ack 408 ignore', but the duplicate ack packets are block 407 in wireshark. It seems different block from two of them. 2. The SAS declaration is that more than two packets are sending on the network between source and destination. But in tftp.c code and above images, The SAS problem seems to be solve.
