Hi, All

     I followed BF518F-EZ-Board Quick Start at http://docs.blackfin.uclinux.org/doku.php?id=quick-start:bf518f-ezbrd and learned to load U-Boot to my BF518F-EZ-Board. There was a problem with loading u-boot over UART, and the error informaction is below.

 

junior@debian:/$ bfin-uclinux-ldr -l /home/junior/u-boot-bf518f-ezbrd-uart.ldr /dev/ttyUSB0 && kermit -l /dev/ttyUSB0 -b 57600 -C connect

Loading LDR /home/junior/u-boot-bf518f-ezbrd-uart.ldr ... OK!

Opening /dev/ttyUSB0 ... OK!

Configuring terminal I/O ... OK!

Trying to send autobaud ... OK!

Trying to read autobaud ... bfin-uclinux-ldr: received signal 14: timeout while sending; aborting

junior@debian:/$

 

What cause this error? Why abort in reading autobaud?

 

Regards,

Junior
