[ECOS] Help me !!, Hello world on out target

[KOHJY]

Hi All!
I am porting eCos on our target which is similar with CMA230(ARM7), 1 timer and 
2 Uart.
I keep running into this problem while debugging with ecos gdb.
When  trying to execute an RAM application(Hello World program).
Look at below.  Downloading is OK.  But RAM application not started  ? 
 
(gdb)0x401440 in ?? ()
(gdb) load
Loading section .rom_vectors, size 0x60 lma 0x8000
Loading section .text, size 0x4eb8 lma 0x8060
Loading section .rodata, size 0x228 lma 0xcf18
Loading section .data, size 0x2b4 lma 0xd140
Start address 0x8060 , load size 21492
Transfer rate: 21492 bits/sec, 298 bytes/write.
(gdb) c
Continuing.
.....................
 
I don't know what happend ?
Is GDB stub ROM  wrong ? or eCos kernel building ?
 
Thanks a lot !

You obviously have a stub there, so I suggest you try to follow the
flow of the code to see what is wrong. It's impossible to tell from
the lack of output what is wrong.

[ECOS] Help me !!, Hello world on out target

[°íÀç¿ë]

Hi All!
I am porting eCos on our target which is simmilar with CMA230.
Now, I am working with ecos-1.3.1 (net-release, 27-03-2000).
I was building and testing GDB stubs ROM.
Downloading is OK, but RAM application is not executed.
CPU core of our target is ARM7 and support  FIQ.  But IRQ is not supported.
Is there anything to change in HAL for FIQ ?
While downloading, Is GDB Stub ROM operated by polled or interrupt ?
Thanks a lot !

You should use the CVS tree instead. 1.3.1 is way old now.

Yes. I can't tell you what off hand though. But I'm sure you'll need
to change some things.

Polled mode only.

I'm using 1.3.1 too (and can't get the TCP/IP stuff installed). Will a CVS 
checkout of today give the complete OS including TCP/IP stack or is the 
networking stuff in a different repository?

Also, is it possible to build the Win32-hosted graphical administration 
tool for the latest eCos version? I like that tool very much.

I think it's all in the same repo now, but I must admit that I'm not
100% sure.

I believe a new version has been uploaded on sourceware somewhere that
handles the new CDL stuff. Again, I'm not sure though.

It is in the same repository but you have to use separate steps to get it.
It's described at http://sources.redhat.com/anoncvs.html under "Optional
networking support".

It has indeed. Again there's a link at
