Message: 55060 please describe your actual setup. what version of u-boot/toolchain are you using ? what hardware are you using ? what is reporting the error ? minicom or the board ? when you reconnect to the board, is it still working ?

i connect the board to the host via serial.
and i configured the minicom as http://docs.blackfin.uclinux.org/doku.php?id=terminal_programs said.
then reset ,u-boot start,
enter "loday"
use the minicom escape sequence (ctrl+a by default) followed by typing s . Select ymodem in the list. Browse to the file select /tftpboot/linux and mark it. Then select OK at the bottom of the file selector.
but an error occurs:failure executing protocol,Press any key to continue....
what is the problem?
thank you!

Couple things:
You said:
>enter "loday"
Do you mean "loady"?
2nd:
What is the minicom config look like?
CTRL-A O (for configuration)
Then
File transfer protocols
| Name Program Name U/D FullScr IO-Red. Multi |
| A zmodem /usr/bin/sz -vv -b Y U N Y Y |
| B ymodem /usr/bin/sb -vv Y U N Y Y |
| C xmodem /usr/bin/sz -X -vv Y U N Y N |
| D zmodem /usr/bin/rz -vv -b N D N Y Y |
| E ymodem /usr/bin/rb -vv N D N Y Y |
| F xmodem /usr/bin/rx -vv Y D N Y N |
| G kermit /usr/bin/kermit -i -l %l -s Y U Y N N |
| H kermit /usr/bin/kermit -i -l %l -r N D Y N N |
| I ascii /usr/bin/ascii-xfr -dsv Y U N Y N |
Do you have the /usr/bin/sb application.
3rd:
have you tried "loadb" with kermit protocol?
