Just curious: what is the typical size of the file that is downloaded via wget? We are observing some inconsistent behavior with wget as discussed in this thread: https://lore.kernel.org/u-boot/CAJ+vNU2U9W2NRT6hf1CAEQ_56SDQviUEzuDD1iYOpdf1CNaZBw@mail.gmail.com/ Do you see the same problem?

I use a 657MB file for my test. I have not focused on the downloading test before, but I also encountered the file size inconsistent behavior on my board(Socionext Developerbox). At the 15 trials of downloading the same file, unexpected file transfer behavior occurred. Packets received 475093, Transfer Successful Bytes transferred = 687929344 (2900f800 hex) Packets received 475105, Transfer Successful Bytes transferred = 687929344 (2900f800 hex) Packets received 475116, Transfer Successful Bytes transferred = 687929344 (2900f800 hex) Packets received 475096, Transfer Successful Bytes transferred = 55088883 (34896f3 hex) <-- size is wrong Thanks, Masahisa Kojima > > Thanks, > > Fabio Estevam
