[ECOS] Build redboot for GRG board with NPE

[Aric Wang]

Yes, I do configure like you pointed out. But it still failed. Then I
changed to the latest eCos source code from redhat. It's ok now. 

Now my problem is, when I try to compile a RAM redboot image and load by
BDI2000. It died on below lines in hal_hardware_init (ixp425_misc.c): 

    // Enable caches
    HAL_DCACHE_ENABLE();
    HAL_ICACHE_ENABLE();

When I commented this out, it died at initializing the PCI.

But for ROM redboot, it runs ok. So I think it must died becuase that the
PLATFORM_SETUP1 (hal_platform_setup.h) macro is commented out in RAM mode
and the BDI2000 didn't initialize the hardware correctly.

Am I right?

How did you configure the build after adding the .epk to your sources?
You should have done something like:

  % ecosconfig new grg redboot
  % ecosconfig import
${ECOS_REPOSITORY}/hal/arm/xscale/grg/current/misc/redboot_ROM.ecm
  % ecosconfig add intel_npe
  % ecosconfig add grg_npe
  % ecosconfig tree
  % make

--Mark
