gdb_monitor_interactive & noux_gdb script problem on pandaboard

[Norman Feske]

Hello,

thanks for giving GDB monitor a try!

There exists indeed no UART driver for OMAP4. So the test will not run
as is. However, you might opt to use the TCP terminal instead of the
UART driver to connect GDB to the debugging target. Both the UART driver
and the TCP terminal provide the same "Terminal" interface. So they are
interchangeable. You can find the TCP terminal accompanied with a small
README file at 'gems/src/server/tcp_terminal'. To integrate it, you will
need a "Nic" service, which is provided by the 'usb_drv' on the Pandaboard.

Btw, there is an UART driver for OMAP4 in the works (it is available at
the Ksys-labs fork, not yet merged into the mainline tree):

I have just tried out the run script and cannot reproduce your problem.
After starting up, GDB greets me with a prompt at the HDMI screen and
accepts commands. Are you using the current master branch of the
genodelabs/genode repository?

For reference, I have uploaded an image of my current build here:

  https://github.com/downloads/nfeske/genode/noux_gdb_panda.img.gz

Can you give this a try? Just uncompress it (via 'gzip -d') and dump it
onto your SD card (via 'dd').

Btw, while playing around with 'run/gdb_noux', I recognized that some
stale files in the '<build-dir>/bin' were causing me problems. The run
script archives the source code and binary of the debugging target at
'bin/test-gdb_monitor-src' and 'bin/test-gdb_monitor'. Please make sure
that your '<build-dir>/bin' directory is free from such artifacts before
executing the run script.

Cheers
Norman
