[ECOS] memory requirements, TI OMAP 5910 (ARM 925T)?

[Jim Partan <jpartan at whoi dot edu>]

Hi,

I'm starting to evaluate the TI OMAP 5910 (ARM 925T) for a new embedded 
system. I'd like to use eCos. Right now I'm specifically trying to 
estimate the approximate memory requirements. I'm just getting the eCos
configuration tool up and going, but if anyone has a vaguely similar
system and can let me know what their approximate memory usage is, that 
would be great!!

I'm interested in using (on ARM 925T):

	TCP/IP stack with embedded webserver
	ethernet driver (perhaps SMSC LAN91c111)
	flash filesystem
	RS232 serial port ('5910 has some integrated UARTs)
	an external realtime clock (probably on I2C bus)
	maybe a few other very small things (watchdog, etc)

	ideally USB as well, but this is not at all critical
		(the '5910 has an integrated USB interface)

The OMAP 5910 has 192kbytes of internal SRAM. I'd love to avoid
putting an external RAM chip on the board. The catch is that
the internal SRAM is shared with a TI DSP sharing the same
package (it's a dual-core package, ARM 925T and TI '55x DSP),
and of course I'd like as much RAM as possible dedicated to the
DSP side of things...

Thanks very much for any help!!

Jim
