            Bug ID: 1001838
           Summary: Freescale EDMA CDL dependency calculation
           Product: eCos
           Version: unknown
            Target: freescale_twr_k60n512 (Freescale Kinetis TWR-K60N512)
  Architecture/Host Cortex-M
                OS:
            Status: UNCONFIRMED
          Severity: normal
          Priority: low
         Component: HAL
          Assignee: unassigned@bugs.ecos.sourceware.org
          Reporter: mjones@linear.com
                CC: ecos-bugs@ecos.sourceware.org

When I disable CYGSEM_HAL_ENABLE_DCACHE_ON_STARTUP, I get a conflict saying
startup mode must be WRITETHRU, which it is , but is also disabled (conflict
comes from CYGPKG_HAL_FREESCALE_EDMA). I believe the correct behavior is for
CYGPKG_HAL_FREESCALE_EDMA to ignore cache mode when cache is turned off.

Thank you Mike. This requirement shouldn't be here so I am removing with this
patch.

Try

$ cd <ecos_repo>/packages/hal/misc/freescale/edma/current
$ patch -p0 -i patchfile


You can safely try different -p values with option --dry-run.
