Re: [ECOS] Re: How to set GDB Stub Options in order to run insight ?

["m mariga" <ma_ariga@yahoo.co.jp>]

Hello,

I changed <CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS> option's defult value from 0 
to 1,
and rebult nc_test_slave.elf and tried to run Insight again.
Then it developed like next log.
{according to Resolve conflicts Winow:
CYGBLD_ISO_FNMATCH_HEADER 
Enabled
CYGDBG_HAL_COMMON_CONTEXT_SAVE_MINIMUM            Diasabled

CYGBLD_ISO_STRUCTTIMEVAL_HEADER                                    Enabled
}

But at this point stuck to silence and no reply like before.

As I compared to previous normal RedBoot Serial log like next, I realized
it stopped at network operation.

Also after changed <CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS> to 1,I loaded 
application and run it on RedBoot,
then where it should appear "Network stack using" like above,it resulted in 
enigmatic numeric codes.

I concluded that according to my changing 
<CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS> to 1,network became malfunctioning.

Anyway I could find a way out of the swamp.
I suppose by handling options properly I could run both GDB stub and network 
properly.
I strongly hope I could debug networking application using Insight.
Would you please help me ?
