Dear all, I'm a newcomer to Yaffs . I want to port yaffs2 to STM32. I took a look at the web site https://yaffs.net/ , especially How Yaffs works, Yaffs Tuning and Yaffs Direct Interface documents. My questions are: 1. What are the source and header files needed to interface cleanly in Direct Interface YAFFS2 ? 2. What is the interface file between NAND memory and Direct Interface YAFFS ? 3. Can you give me a project on any C compiler to get an idea about the integration model ? 4. Can you give me an idea about the required footprint ROM/RAM? 5. What are the first steps to follow to run the Yaffs Direct Interface features? Best Regards, GO.
