RE: about porting ecos in S3C4510B development board


I am following the step-by-step instructions stated in
http://www4.ncsu.edu:8030/~abdudani/ecos/docs/hal-porting-platform.html

1. I copied the all files/directories in the hal/arm/SNDS into a new folder
which I name as /hal/arm/test.

2. I changed the name of the following files:

  subdirectory cdl
    	hal_arm_snds.cdl		->		hal_arm_test.cdl

  subdirectory include\pkgconf
  	mlt_arm_snds_ram.h	->		mlt_arm_test_ram.h
  	mlt_arm_snds_rom.h	->		mlt_arm_test_rom.h
  	mlt_arm_snds_ram.ldi	->		mlt_arm_test_ram.ldi
  	mlt_arm_snds_rom.ldi	->		mlt_arm_test_rom.ldi

3. I add the package and target descriptions to ecos.db

   package CYGPKG_HAL_ARM_TEST {
      alias       { "TEST" hal_arm_test arm_test_hal}
      directory   hal/arm/test
      script      hal_arm_test.cdl
      hardware
      description "
          The S3C4510B TEST package provides the support needed to run eCos
on a
          Samsung S3C4510B TEST board"
}

target test {
      alias { "S3C4510B TEST" TEST test test100 }
      packages { CYGPKG_HAL_ARM
                 CYGPKG_HAL_ARM_TEST
               }
      ##enable { CYGHWR_HAL_ARM_BIGENDIAN }  // BIGENDIAN is disabled
because my board is LITTLEENDIAN
      description "
        The test target provides the packages needed to run eCos on a
        S3C4510B TEST board."
}

4. I modified the hal_arm_test.cdl and the .mlt .h files for the memory
layout:

*******hal_arm_test.cdl:
******* basically I just replace the "snds" with "test"************

After these I build the Redboot using eCos configuration tool.

Forgot to tell you that the data-bus width for the FLASH and SDRAM are all
16-bit wide. I think this is different from the SNDS board, where could I
change the data-bus width? in the hal_platform_setup.h?

How could I make the Redboot support AM29LV160 FLASH? Does it support SDRAM?

Thanks a lot!

H.Y. Roger

Please describe in more details the steps you took so we can tell you if
you took a wrong turning. In particular did you remember to import the .ecm
file? Since you ask:

>     Do I need to include Flash driver for Redboot?

There is no flash driver for the SNDS, sorry.

Depends what's fitted, the closest would be S3C4510A. It's possible that
there's a difference between the A and B revisions - you'd need to see the
documentation for the chips to find out for sure. The B may just be an
errata fix version of the chip.
