Hey, Today I have just downloaded the PPPStack.zip(I dont remeber well the
name) and tried to compile it into a new kernel using:
$ecosconfig new eb40a net
$ecosconfig add ppp0 (no conflicts here)
$ecosconfig tree
$make
Just in the chap compiling some parse errors apeared, it's from my target?
or maybe some really parse errors?, maybe I have done something wrong? Or
maybe missed something? Im pretty interested on PPP over eCos.
If you want the output I will post it.

Again I used this lines to compile the kernel with "NET" support
> $ecosconfig new eb40a net
> $ecosconfig tree
> $make
>
No errors during compiling, still, compiling the examples, the same error
appeared on all,
../arm-elf/bin/ld: address 0x85df8 of hello section .bss is not within
region ram
Well, I dont know why this happened, but I suppose that the eb40a has not
enough memory to suppor the stack, I have gotten this error before and was
when I overpassed the ram limit of the board, therefore, why the error
appears in a code like a simple hello-world?
Or that template NET is not intended to run for the eb40a?
Thanx you all.
Xcuze me If the questions has "obvious" answers. I'm still learning the eCos
thing.

The eb40a has for a RAM application 256kb internal ram which is shared for both
debugger (redboot, ~60kb), program code and data (stack, heap, constants, bss).
If you have placed external ram, the linker script must be changed to use it,
providing that the memory interface (EBI) is already configured for that memory.
Redboot should have done this already in vector.S and hal_platform_setup.h
For a ROM application, the program code comes in FLASH and no debugger has to
be used to load your application. This will give you more free ram. But as you
replace redboot, I would not recommend it. Too much trouble.
1) expand your eb40a with extra ram, if not already placed (I have never done it
myself)
2) check if redboot does set up the EBI interface correctly.
3) change your linker script (target.ld) to place the bss section in the
external ram. See if there is enough stack space and heap space left.

Well, the eb40a has 512k of RAM, I suposse that the space avaliable for the
stack is much less,cuz the other pakgs.

You might want to try the LWIP with its ppp stack, it should be smaller.

This is not going to be much help, But I think you are right. It sounds like
you are running out of RAM memory. Just the net component on its own without
the PPP stack is large (in embedded terms).
How much memory have you setup the target to have?
