  i tried doing this "cu" command and it send the expected packet which 
indicates that serial link does not have any problem .

  ya ! some chracters are displayed on the screen , even when the program is 
loaded , some characters are displayed on the pc . But still it is giving 
the same error while downloading :
ignoring packet error, continuing ...

today, i tried downloading the hello executable , but it also did'nt worked 
. it downloaded all three sections ( .rodata, .data, etc )while giving the 
same message in between . it took more than 1 hr for this ..in the last it 
showed that the transfer rate was 33 bytes/sec.
i have not enabled any drivers .. do i need to make some changes in ecos.ecc 
files for stubs and then build it .

regards
danish.
