hi,all i porting u-boot-1.3.4 to s3c44box.when i porting uclinux to board, then there is the problem as follows:
END-class command failed. Packets sent: 1301 Retransmissions: 11 Timeouts: 0 Damaged packets: 0 Fatal Kermit Protocol Error: Too many retries HINTS... If the preceding error message does not explain the failure: Try changing the remote Kermit's FLOW-CONTROL setting. Try it again with SET STREAMING OFF. Try it again with SET PARITY SPACE. As a last resort, give a ROBUST command and try again. Also: Be sure the source file has read permission. Be sure the target directory has write permission.

Well, did you read what kermit printed out for you? And did you follow the hints?
Or did you read the manual, say section "4.3. Configuring the "kermit" command" at http://www.denx.de/wiki/view/DULG/SystemSetup#Section_4.3. ?
