Re: [ECOS] Build->Packages WinNT eCos Config Tool Error

[Sergio Nunes]

Jonathan,

I've resolved my problem. Thanks for your help. As you mentioned in initial
reply, I only get the warning message when I try to add/remove "hardware"
packages.  I'm able to remove other eCos packages without problems.

Sergio

I don't really want to edit these templates. What I would like to do is
add/remove packages from an existing eCos Configuration using the eCos

something wrong or is this a bug.  What's the prupose of the Build->Packages
function if it gives you an error/warning everytime you try to change a package.

There's no GUI way to edit templates. They can be found in the
packages/templates directory of your eCos installation and can be carefully
hand-edited there.

But do you really want to do this? If a package is marked as "hardware" and
isn't already in your configuration, it probably doesn't work in any other
hardware.

But it doesn't if the package is not a hardware type package.

For example, you could add or remove the uITRON compatibility package, or
the POSIX package and it would be fine.  Try it please?  If you cannot do
that, then you have indeed found a bug in the Config Tool!

But hardware packages are labelled hardware because they can only be used
on certain hardware.  It makes no sense to add the flash driver for an
EBSA285 board to a build for PowerPC PBX board, so you can't do that.

If you are working on a new platform, and you want to re-use some hardware
packages from a similar existing platform, that's easy.  For your new
platform you must have created a "target" entry in ecos.db - at the very
minimum you will have listed HAL packages for the new target there, so if
you list _all_ the hardware packages to use in the target entry, they will
be included when you select that platform as the build target.

For example

    target nano {
      alias { "nanoEngine StrongARM SA1110 board" nano nanoEngine }
      packages { CYGPKG_HAL_ARM
	  CYGPKG_HAL_ARM_SA11X0
	  CYGPKG_HAL_ARM_SA11X0_NANO
	  CYGPKG_IO_SERIAL_ARM_SA11X0
	  CYGPKG_DEVS_FLASH_NANO
	  CYGPKG_DEVS_FLASH_STRATA
	  CYGPKG_DEVICES_WATCHDOG_ARM_SA11X0
	  CYGPKG_IO_PCI
	  CYGPKG_DEVS_ETH_ARM_NANO
	  CYGPKG_DEVS_ETH_INTEL_I82559
      }
      description "
      The nanoEngine target provides the packages needed to run
      eCos on a Bright Star Engineering nanoEngine StrongARM SA1110 board."
    }

Every one of those packages listed is marked "hardware" because they are
hardware specific; it is pre-defined what targets they can work with, and
selecting one of those targets is the only way to include these packages.

Note that this does not mean that all builds for this target will be
bloated by unused code; many of these platform specific packages
(eg. CYGPKG_DEVS_FLASH_* and CYGPKG_DEVS_ETH_*) will be inactive unless the
generic device driver (CYGPKG_IO_FLASH and CYGPKG_IO_ETH_DRIVERS
respectively) are also included.  And whether to include those generic
drivers is controlled by the Build->Packages facility or the template
chosen or "ecosconfig add", and so on, like any non-hardware-specific
package.

[ECOS] Build->Packages WinNT eCos Config Tool Error

[Sergio Nunes]

I get the following error/warning message "Add and remove Hardware Packages by
selecting a new hardware Template" when I try to create a build package using
the Build->Package option under WinNT version of eCos configuration tool.

I'm unable to locate a GUI method of creating new templates within eCos
configuration Tool. Any ideas how to workaround this problem manually. I have
v1.3.1 installed.  I don't necessarily need to create a new template, but would
like to edit existing templates to create a specific build configuration.

Thanks,

Sergio
