Yes, YAFFS should have been the solution if it was under the same
license of eCos.

My board is an ERTEC200 evalution board (DevKit) from SIEMENS. For the
flash, it uses the general flash support package with a specific flash
memory device support (AMD AM29XXXXX). The ERTEC and board
architecture support are provided with the DK.
The problem with this DK is that the eCos version is not fixed, it
seems to be post eCos v2 but pre eCos v3.0. Is there a mean to know
the exact version I use?
I downloaded the YAFFS package (file .epk) to evaluate it, but I was
unable to add the package to the repository, the configuration tool
ended with an error when importiong the .epk file...

Paul
