really thanks.....what you write for me is very detailed.....thanks again.but for me ,what really worry me is how to flash the u-boot-para in board...i need these details. For example ,when i flash,the switch 2  point position 1? baudrate 57600 8n1 ?

  I really do as you say ."  here is my fact as follow:

hardware: blkfin 609,usb-serial 2.0 cable to my ubuntu host; the switch 2 position is 2(1 also tried)

software: ldr-utils is ok; the u-boot is para-u-boot from where you write;

when i flash as the command"bfin-uclinux-ldr -l /tftpboot/u-boot.ldr /dev/ttyS1 && kermit -l /dev/ttyS1 -b 57600 -C connect"   always error as follow:

 

opening /dev/ttyS1  ok

configuring terminal I/O ok

trying to send autobaud  ok

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

 

where the problem comes from......

 

 

i need these details.....thanks
