[ECOS] Debug output

[ECOS] Debug output

[Trenton D. Adams]

I noticed that my serial I/O is sending some debug info too if I run my
ROM based program.  Running the RAM based programming using RedBoot
doesn't send this information to the serial port, but does send it back
to GDB.

Network stack using 65536 bytes for misc space
                    65536 bytes for mbufs
                    131072 bytes for mbuf clusters
serial example is working correctly!

I'm using TCP/IP to connect so I can use the serial port separately from
the GDB connection.

How do I get rid of this?  I assume it's an option in the eCos config,
but I can't seem to find it.

I'm not entirely convinced about it's use now myself. When the TCP/IP stack
was new it was informative, but now we could make it optional.

For you, work around it by editting net/tcpip/current/src/ecos/support.c,
in the function cyg_kmem_init().

Gary, any reason not to make a config option that controls debug output. It
could be a component that included other things like DHCP_CHATTER.

So from what I gather, this is not output to the serial port when my
program outputs to the serial port, but when the system starts up right?
So, diag_printf () prints to the first serial port by default then
right?

The default serial port for diag output is defined in your configuration.

Does that mean it's hardcoded in or available as an option in my config
tool?  If it's an option, where do I find it?

I decided to work around it by switch the diag output to UART2.

That would be fine.  These messages are indeed vestiges of early testing of
the stack.

So, when can we expect that in CVS?  No RUSH now! :)

CVS releases normally happen weekly on a Friday. That's the goal anyway.

Never mind, I found it.  It's called "Debug serial port".

I mean "Diagnostic serial port".

Remember this is only the default. It _can_ be changed at runtime. But
please don't ask me how unless you really need to know :-).
