Re: TCP Stack Testing problem

Thanks a lot.

I have tried to compile redboot code and tried to generate library but it was giving lot of errors and warnings.

I want to ping to target system.

To do that is it compulsory to go for redboot support.Is there any other way apart form redboot package selection.

Regards, Madhava S

Hi All,

I am new to eCos and currently learning to work on x86 PC platform.

I want to test the working of TCP/IP stack.

I was able to compile and run a sample application using boot floppy
through serial port.

How can i test the same program using Ethernet port.
In the configuration tool i have selected "common ethernet support",
"networking" and "Open BSD Stack" packages.

Rather than add packages like this, use the templates, eg net and old_net.

I have generated the library for my work_dir.
Then i have compiled the program using
i386-elf-gcc -g -I$(work_dir)/include/hello.c -L$(work_dir)/lib -Ttarget.ld
-nostdlib -o nw_test

Generated the binary of that exe
i386-elf-objcpy -O binary nw_test nw_test.bin

copied to floppy
dd conv=sync if=nw_test.bin of=/dev/fd0

I compiled the target for booting from floppy.
Started the target.

On Host i started gdb
i386-elf-gdb nw_test
when i try to connect using "target remote ip:port"
it says destination unreachable.

Only redboot contains a tcp/ip enabled stub which can be used by gdb. Your FLOPPY startup application only has a serial port gdb stub. This is not a problem though, normal TCP/IP will still work and you just need to use the serial port for gdb.

Also, rather than writing your own test programs, i suggest you first
use the eCos test programs. These are known to work. Enable

make tests

and run the applications in install/tests/net/bsd_tcpip
