Hello,

I am trying to debug my applications with gdb. I have enabled CONFIG_USER_GDBSERVER and I compiled my application with "-g -O0" compilation option.

Then I start gdbserver on target(ADSP-BF537-STAMP) as "gdbserver /dev/ttyBF1 program.gdb" the result for this is

Process ./program.gdb created; pid = 70

Remote debugging using /dev/ttyBF1

On host(Colinux):

bfin-uclinux-gdb -b 57600 program.gdb

gdb)target remote /dev/ttyS0

Remote debugging using /dev/ttyS0

Ignoring packet error, continuing...

warning: unrecognized item "timeout" in "qSupported" response

Ignoring packet error, continuing...

Malformed response to offset query, timeout

gdb)start

Don't know how to run. Try "help target".

I am using latest uClinux-dist and toolchain from svn trunk

Could you please help me why is that error coming?

Regards

Parimala

I am using the gdb client what ever uClinux-dist has(bfin-uclinux-gdb) that shows the version as "GNU gdb 6.6". Do I need to upgrade this version?

Thank you.
