RE: [ECOS] about porting ecos in S3C4510B development board

[Jay Foster <jay dot foster at systech dot com>]

I ported RedBoot to the (my) SNDS100 board more than a year ago.  I remember
modifying the HAL startup code to get the SDRAM configuration correct, and
added a flash driver (for the Winbond w29eexxx devices).  I submitted
patches for these, but much of it never made it into the repository.  I
don't know if all SNDS100 boards have the same flash devices or not, so this
flash driver may not work for your board.  I suggest searching the eCos
archives.  I have an update to the winbond w29eexxx flash driver that allows
it to work with eCos, but I have never submitted it, since there seemed to
be no interest.

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:

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.
