[Yaffs] build, port YAFFS directions/examples

Hello All,

Please could you point me to any examples of how YAFFS can be build, ported
into a NON Linux or eCos environment.

I am using WICED framework (Broadcom's wi-fi). I have a choice of using
either FreeRTOS or ThreadX on a custom board (STM32 + bcm43362). I would
like to see an example of how building, porting could be done in general.

Everything I googled on the internet is for adding YAFFS into Linux
kernel. Scripts that are in the YAFFS repository are for building into
Linux. So far I could not figure out how to make adaptions for anything
other than Linux or eCos.

I would appreciate any directions for how YAFFS can be ported onto a raw
Nor flash.

Thanks in advance,
Oleg
