Hello,

How do you use the SPI bus for ARM with eCos ?

Which ARM processor are you using?

For the Atmel family, there's an SPI driver available: devs/spi/arm/at91/

eCoscentric has some pretty decent documentation about eCos and SPI:
http://ecoscentric.com/ecospro/doc.cgi/html/ref/spi.html

To enable the driver you have to add these CDL packages to your platform:

 CYGPKG_IO_SPI : enables the SPI generic interface layer
 CYGPKG_DEVS_SPI_ARM_AT91 : enables the at91 SPI bus driver

You'll have to define an extra package to export your SPI devices,
like you do for i2c.
A good starting point might be the at91sam7sek target.

You can just use C-code, but if you are using a target that is already
supported there is a big chance there's a cdl package define all
devices for that specific hardware target. For my hardware, I usually
create such a cdl package.

See the the ecoscentric documentation about SPI.
I was just referring to the at91sam7sek target as an example on how to
add the required SPI cdl packages to your target.
