[ECOS] MBX Board/Redboot

[ECOS] MBX Board/Redboot

[Anthony Massa]

I have Reboot running on my MBX board.  I am able to download my application
code to the board using TFTP.  After I download the code to RAM, I use the
Reboot GO command to execute the code.  I then see a string output to the
serial port.  I then tried to connect GDB/Insight via the serial port to the
board for debugging.  How then can I do source level debugging on the board
- is it possible?

I want to be able to have the serial port for my applications I/O
communication and use the Ethernet interface for debugging.  I have tried to
connect GDB to the board via Ethernet, however, I have not been able to do
this successfully.  Can you tell me the steps and the any packages or
options I need for the eCos configuration to accomplish this?

I was also wondering with the MBX860 template and the networking package, do
I need to add the Common Ethernet Support package or is this functionality
taken care of with the QUICC Ethernet package?

What functionality does the Common Ethernet Support package add?

Thanks.

Yes, but you need to connect to RedBoot via ethernet from GDB and
download the application from there.

You don't need the ethernet support in the application. All the
necessary bits should be in RedBoot. As far as I know, anyway.

So, just to confirm, I would basically use RedBoot the same way as I would a
build of a
GDB stub.  Except RedBoot gives me the additional feature of being able to
debug via Ethernet.
Right?


I tried a different eCos configuration using the MBX board as a template and
then selecting the net
package (on the template dialog).  I downloaded the srec file using RedBoot
and then ran it.  What I
saw was a string of characters starting with $, then after some delay the
message:

Network stack using 65536 bytes for misc space

came out and then a bunch of unreadable characters.  It almost seemed like I
had the serial port
configured to the wrong baud rate - although I didn't.

I am trying to get the GoAhead web server running in my application.  I
guess I want to just be able
to use RedBoot to download and debug code (using GDB through RedBoot).  If I
use the networking and
Ethernet drivers in my application will it create a conflict with the
Ethernet drivers in RedBoot - or will my
application still be able to receive its packets and send out the web pages
requested?

If I use the Ethernet port for debugging, can I send and RECEIVE console
commands over the serial port?
(because I know if I debug over the serial port I can't receive any input
from into my console thread) 


Thanks - again.
