[ECOS] AT91EB40 networking problem

[ECOS] AT91EB40 networking problem

[Bryan Mok]

Hi all,
	I am working on AT91EB40 with AT91R40807 processor. I
have downloaded the pre-built binary in web and
followed the Redboot's user guide to install Redboot
to the board. Then I have built eCos and compiled
"hello world" testing program. It runs very well. 
	Now I am working on the communication programming for
the same board. I have add the TCP/IP
packet(net-1.0b1.epk) to eCos. I can build the eCos
from net template without error. But I can't build the
network testing program. The following is the commands
that I used to build the eCos and the testing program.

% ecosconfig new eb40 net
% ecosconfig tree
% make
% make -C net/tcpip/current tests

make: Entering directory
`/opt/ecos/ecos-1.3.1/eb40-net/net/tcpip/current'
arm-elf-gcc -mcpu=arm7tdmi -mno-short-load-words

/opt/ecos/ecos-1.3.1/eb40-net/install/tests/net/tcpip/current/tests/ping_lo_test

section .bss is not within region ram
collect2: ld returned 1 exit status
make: ***

Error 1
make: Leaving directory
`/opt/ecos/ecos-1.3.1/eb40-net/net/tcpip/current' 

	What should I do? Should I modify the memory layout
so that section .bss become within region ram? If yes,
which file should I modify?

	Thx for any help!

Regards,
  Bryan Mok

Problem appears to be that the test is too big for the available
memory. Look for the RAM startup .ldi file and make sure the memory
size is correct. If it is, there's little you can do, other than try
to reduce the size of the test.

Hi,

I have checked the .ldi file. The memory size is
correct there. And I also tried to compile a "hello
world" test. It fails again with the same error :
"section .bss is not within region ram collect2: ld
returned 1". 
Is the problem of the starting address? Or does the
tcpip stack not available for the AT91EB40 platform
yet?

Including the TCP/IP stack makes no sense on this hardware at
this time - there is no ethernet driver defined for it and we
do not yet support serial (PPP) based networking.

Sorry.
