* 현재 yaffs2가 마운트는 되는데 파일 쓰기 중 에러납니다.
아래 설정 및 실행결과를 올립니다.
어떻게 해결해야 되는지 아시면 좀 알려주시면 감사하겠습니다.

자답이네요.
해결됐습니다.
1. 노드를 생성안했군요.
#mknod /dev/mtd3 c 90 6(mtd 3번, rw 타입)
*아직 마운트를 안한 상태에서 블럭 디바이스로 접근하기 전이라서 캐릭터 디바이스로 다루어야 하기 때문일 것이라고 합니다)
참고로 mtd의 마이너 번호는 다음과 같네요. read only의 경우 홀수가 되네요.
mtd0
mtd0ro
mtd1
mtd1ro
mtd2
mtd2ro
mtd3(minor number 6)
2. 다음, 아래 문제가 나온 까닭에 해당 플래시 파티션 데이터 삭제해 줬네요.
#cp 1.wav /mnt2
yaffs tragedy: no more erased blocks
!!!!!!!!! Allocator out !!!!!!!!!!!!!!!!!
yaffs tragedy: no more erased blocks
!!!!!!!!! Allocator out !!!!!!!!!!!!!!!!!
...
플래시 파티션 데이터 삭제
#./flash_eraseall /dev/mtd3
Erasing 128 Kibyte @ 3d40000 -- 99 % complete.
/dev/mtd3 노드 파일이 없으면 플래시 삭제 안됩니다.(당연히;;)
3. 마운트 : 아래와 같이 마운트하면 정상이네요.
#mount -t yaffs2 /dev/mtdblock3 /mnt/yaffs2fs/
yaffs: dev is 32505859 name is "mtdblock3"
yaffs: passed flags ""
yaffs: Attempting MTD mount on 31.3, "mtdblock3"
yaffs_read_super: isCheckpointed 0
* 참고로 yaffs2 사용하기 위해 빌드한건
1. yaffs2 소스 : 커널 패치후 make menuconfig로 yaffs2 설정
2. mtd utils 소스(flash_eraseall) : 사용하는 bsp에는 없어서 크로스 컴팔 후 타겟 복사
입니다.
