[ECOS] Status of at91sam7xek

[ECOS] Status of at91sam7xek

[David.Babin]

Hello,

Since 3 days, i try to flash my at91sam7x256-ek board without success !
Maybe something wrong in my configuration.

I use cygwin with make 3.80-1, last cvs version, last configtool 
available.

i can't build os with at91sam7xek/lwip_eth using configtool. this message 
appear :

 
/opt/ecos/ecos-cvs/ecos/packages/services/memalloc/common/current/src/dlmalloc.cxx:

        make: *** [build] Error 2

 
When i choose at91sam7xek/minimal, build work fine, but when i try to 
compile my simple hello world (after remplaced printf with diag_printf) 
this message appear :

        collect2: ld returned 1 exit status

So is the status of this board is ready to use ?
How can i check my environment to know if something missing ?
Is there any tutorial for this board anywhere on the web ?

Thanks for help :-)

At some point i want to improve this.

You forgot to rm -fr your tree when you changed configuration. Your
library has a mixture of both the old and new configuration.....

Re: [ECOS] Status of at91sam7xek

[David.Babin]

Thanks Andrew,

libc_string seem to be not needed anymore after this patch.
Compiling give some new problem because ram is not enough on board.

But i can see for first time my Hello World on serial debug !!!! it's 
little step for me and just a little step for me.... :-)

So now, i will check how to add RAM on my board :-)

The AT91SAM7XEK does not have an external memory interface. So you
need to live with what you have on chip.

You don't need to run all the test programs. Some do require a lot of
memory, eg tm_basic, but others will compile and run. There is a lot
of tuning you can do with stack sizes etc.

I suspect that the embedded 64k will not be sufficient for my usage :
PPP - Ethernet - IP Stack (TCP/UDP/DNS) - Flash

After some research, i've seen that adding memory can be done via SPI
bus with SRAM.
In this way ecos can be running with light modification on ldi files,
seen in this post :
http://sourceware.org/ml/ecos-discuss/2003-10/msg00338.html

Can you confirm me it's the correct way ?

David.

I think this is very unlikely to work. The AT91SAM7X cannot map SPI
memory into its normal memory map.

What you need is an external memory bus. The AT91SAM7SE devices have
this, but i don't think there is an AT91SAM7XE.

I suggest you find somebody inside your company who has more
experience with low level software and hardware.

Depending on the memory needs of your application, 64k should be
doable, at least for a basic IP stack. Do you really need TCP and
UDP? You surely won't need "advanced" tcp features like the more
complicated flow control algorithms, window scaling etc.

There are people doing a webserver in about 1k of code
(http://d116.com/ace/), on a Lego Mindstorm or even a C64
(http://www.vnunet.com/vnunet/news/2118399/commodore-back-web-server).

(Yes, I admit, they don't do eCos).

Markus
