["zheng wujun" <wj_zheng10 at hotmail dot com>]

Hi,all:
I'm a newbie to ecos,and I have already installed ecos on my PC running 
Linux OS
,and built a redboot image for my board--samsung snds corectly.But there is 
some

questions want to get your kindly response.

1.
When powered,redboot can executed correctly,but there no those commands 
which pre

fix is 'f-',such  as 'fis','fconfig',why?

2.I also built a executeable application according to ecos mannul,and 
downloaded

by tftp to address 0xX on board,but when type comamnd 'go 0xX',then the 
board was

died.why?

the information displayed as below:
  RedBoot> load -v -r -h 192.168.20.172 -m tftp -b 0x800040 /tftpboot/hello
  -
  Raw file loaded 0x00800040-0x0091fcae, assumed entry at 0x00800040
  RedBoot> go 0x00800040
  
$T0a0f:30038001;0d:fbefffff;#b3$T0a0f:30038001;0d:fbefffff;#b3$T0a0f:30038001;

3.when I build redboot image or kernel with ecosconfig command,the steps
below is correct:
(1) %ecosconfig new snds redboot
(2) %ecosconfig tree
but!!!
(3) make
cannot passed.and information below was displayed on:

                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
                from /usr/local/arm-elf/stlport/stddef.h:23,
                from 
/home/examples/kernel/install/include/../include/stddef.h:64,
.....
.....
.....

If it is releative to file as such sentence "#include_next" in file 
"stddef.h" or
"stdarg.h" and so on?

why?

Would you please give me some hints?Thank you very much!

Best regards!
