28페이지에 보면 make mkyaffs 와 make mkyaffsimage를 실행 시켜야 하는데.
make mkyaffs는 보드에서 실행시키위해 크로스 컴파일을 해야하는 한다고 되어 있어
Makefile을 아래와 같이 수정 했습니다.

에러 나있는 부분을 보면 mtd/mtd-user.h 라는 파일을 찾지 못해서 인거 같은데
어떻게 해야할지 조언을 부탁드립니다. 읽어주셔서 감사합니다.
2.4.x 대 커널에서만 유용합니다. 실제로 mkyaffsimage의 경우도
존재하기는 하나(2.6.13 작업할때도) 컴파일은 에러가 나더군요.
수정할까 하다가 그냥 놔뒀었던 기억이 나네요.
만일 2.4.x 커널을 사용하신다면 2.4.x용의 yaffs source를 가지고
작업하셔야 합니다.
2.6.x용으로 나온 녀석은 필요도 없고, 컴파일도 안되는 듯 하더군요.
yaffs2가 아닌 yaffs의 경우 mkyaffsimage의 경우는 kernel 2.6.x대에서도 2.4.x 대 용으로 컴파일된 녀석을 가지고 image를 만들고
aesop의 u-boot에서 write해도 잘 되긴 합니다.
