Hi,

 

We are looking to use Yaffs as a high integrity file system on an Arm7 chip
running FreeRTOS, using micro SD card for storage. I have basic capabilities
running using:

- YAFFS2

- Inband tags

- Yaffs Direct interface. 

 

My concern is the resources used: the code size is around 110kB, and static
SRAM requirement is 9kB, with additional memory required at execution time.
We are looking to achieve about half these values. (I note that the guidance
at http://www.yaffs.net/yaffs-memory-footprint seems significantly different
from what we are seeing.)

 

The key questions are:

1. Is what I am seeing appropriate for the configuration we are using?

2. Is it realistic to achieve 50kB code size & around 10kB RAM using Yaffs?

3. If Yaffs can't meet our resource requirements, what alternative file
systems might be appropriate?
