Hmm, sounds like you don't use any flow-control on the serial port so when u-boot goes away to do work it signals the other end(your host running Terraterm/HyperTerminal) to stop transmitting until u-boot's serial fifo has room in it. If Terraterm/HyperTerminal don't have the right flow-control setup then they'll keep tyring to stuff data into the fifo (which gets dropped on the floor). > I also tried sending a file with the protocols Xmodem, Ymodem, Kermit. > Thy do not seem to work, or it is getting garbage (i.e. protocol specific > headers, where it expects to see the actual S-record). > > Our U-boot is based on 2008.10. > > > Any files attached to this e-mail will have been checked with virus detection > software prior to transmission but you should carry out your own virus check > before opening any attachment.
