[ECOS] Advice on hardware choice

[ECOS] Advice on hardware choice

[Paul D. DeRocco]

I'm starting a "hobby" project based on eCos, so I have to use the free
version, but I'm not wedded to any particular hardware platform yet. Before
I go through the excruciating process of investigating all the hardware for
which free eCos includes board support packages for, I thought I'd just ask
for advice. My hardware requirements are:

	Roughly the horsepower of a 200MHz ARM
	At least 4MB RAM on a 32-bit bus, preferably single SDRAM chip
	Don't want NOR flash on board (boot from internal or SPI flash)
	100mb/s Ethernet interface
	Full speed USB slave interface
	SD card interface

If the support is for some off-the-shelf eval board, I'll basically use it
as the basis for my own hardware design, so the BSP should work pretty much
as-is.

If I had the money to buy a package from eCosCentric, I'd just go for the
AT91SAM9260, but I can't justify it for a hobby project. Do any of the stock
packages included in the distribution come close to the above features?

Take a look around. There are some partial ports available, eg

Evgeniy Dushistov has some eCos patches for AT91SAM9263:

Another possibility is the EP93xx board support from Cirrus Logic:

  http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000739

However, it looks like the EP93xx processors do not provide USB slave.

You might also wish to look at some of the more powerful PowerPC boards.

At first glance, that doesn't look too "partial" so I think I'll give it a
try. Thanks.

Thanks. Looks interesting.

Funny, three host ports and one slave seems a tad lopsided. ;-)

I didn't see any integrated Ethernet, and parts count is an issue.

Thanks for the tips. I'm going to start out with the Ronetix package, and
see how that goes.

There might not be a eCOS port to this chip, but it does look interesting...

The three host ports are provided my the EP93xx processor itself.  The USB
slave is only on some of the EDB93xx boards and is provided by an external
chip.

Does anyone know if the FSF copyright assignment is completed to get
the ep93xx support into CVS?  I have a number of patches I would like
to submit.

Regards,
Hartley

It does indeed. An ARM9 platform for EUR 69!

The LPC2478 stick also looks interesting. eCos should port very rapidly
to this one since we already have support for an LPC2468 board.
