Re: GDB 5.2, NetBSD 3.0, serial connection [/dev/dty00] failure


possible reasons could be permissions like ls -l /dev/dty00 can show you
or is the correct module inserted.
Another thing could be target remote or target rdp , after gdb to a
help target so see which targets are supported. I think this is the
reason.

I am hoping for some guidance to help troubleshoot a serial connection
failure using arm-elf-gdb 5.2, running on NetBSD 3.0:
    This GDB was configured as "--host=i386-unknown-netbsdelf3.0
--target=arm-elf".

We have an Atmel eval board [EB40A] connected via a serial cable running
Angel.  We are able to communicate with the board using "tip -9600 dty0"
and also using minicom, configured to /dev/dty00.  However, when we
attempt to connect with the board using GDB we see:

(gdb) set remotebaud 9600
(gdb) target rdi /dev/dty00
Could not open device "/dev/dty00"

...since we are able to talk to the board using both tip and minicom,
this seems to be specific to GDB.  Any suggestions would be appreciated.

Thank you,
