[ECOS] SPI support for AT91SAM7XEK.

[ECOS] SPI support for AT91SAM7XEK.

[Chirag shah]

Dear All,
	I have successfully accessed uart0 of my SAM7XEK board which was my
previous question on this mailing list.

I have enabled UART0 port in 
IO_sub-system
----->serial_device_drivers-->Hardware_serial_devide_drivers----->port0
through ecos configuration tool.
	After that I have use /dev/ser0 in cyg_io_lookup().

Now I want to enable my SPI bus in SAM7XEK board.
In ecos package directory structure it is already implemented for SAM7, but
in configuration tool SPI driver package CYGPKG_DEVS_SPI_ARM_AT91 can not
get enabled. It can not be accessed as check Box like serial driver drivers.
	So, how I could get SPI header files in cyg/IO/spi_at91.h

Please advice.
Thanks in advance.

Regards,
Chirag Shah

Add the generic SPI package to your configuration.

Dear Andrew Lunn,

	Thanks for your guidance. But I know that I have to add package for
generic SPI. But when I am trying to add package from windows based
configuration tool through build ----> packages and trying to add generic
SPI package it is prompting that " Add and Remove hardware packages by
selecting a new hardware template ".

	And another way is through Tools---->Administration. When I am going
to Add generic SPI package it is asking for .epk file to be opened. I
searched in my local drives that there is no such extension file is
available. 

	So, how can I add this package to my configuration. I think this is
the same problem for Ethernet also.


Regards,
Chirag Shah.

The GUI configuration tool does not allow you to add "hardware"
packages to an eCos configuration. ecosconfig does not impose this
restriction and that is what i always use, so i've not seen this
problem before.

This difference has been discussed before, so search the mail archive
for more information.

This is used to add a package to a repository. SPI is already in the
repository, so you don't need to add it this way. You just want to add
SPI to your configuration.

Use the net template. Or more likely, the lwip_eth template.
