as you've been told many times, read the documentation.  there is a troubleshooting section already.

mike

 

sorry for this i am very new to this field

 

i will expline wat i did

 

as i told u i used ldr viewer to load uboot .it went fine

 

i opened kermit and tested using troubleshoot manule in douc.which say

 

    start up your favorite communications application, pointing it to the same serial port as you where using for the ldr utils:

 

    rgetz@pinky:~> kermit -l /dev/ttyUSB0 -C connect

    Connecting to /dev/ttyUSB0, speed 57600

     Escape character: Ctrl-\ (ASCII 28, FS): enabled

    Type the escape character followed by C to get back,

    or followed by ? to see other options.

    ----------------------------------------------------

 

    hit the reset button on the Blackfin

    press the space bar in the serial port session one time

    the Blackfin should respond with two unprintable bytes (the exact bytes displayed might differ based on your setup)

 

    ��

 

 

    when i did this, on my serial port session it printed only one unprintable byte insted of two

 

    so i am confuse weather my boot load is sucessful or not

probably due to your host locale.  as long as the proc responds with something only once per reboot, it should be fine.

it doesnt mean ldrviewer will work.  we didnt write that package and it's known to not always work properly.
