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.
