안녕하세요.
고도리입니다.
pollux보드의 MLC nand에 ubi/ubifs/ubiblk를 올려봤습니다.
커널 버전은 ubifs-v2.6.24 고요.
ubi는 mtd위에 올라가는 logical volume manager라고 보시면 되고요.
ubifs는 ubi위에 올라가는 새로운 filesystem입니다.
조만간 yaffs는 거의 없어질 듯 보여지고요.
2.6.27 커널서부터는 공식으로 들어간댑니다........ㅎㅎ
ubiblk는 ubi위에 올라가는 block device이고요.
vfat/ext3등을 direct로 nand위에 올릴 수 있습니다.
ㅎㅎ
일단 ubifs를 올린 로그를 올립니다. 아주 재밌고, 오묘합니다.
자료가 너무 없어서 엄청 고생했습니다.
특히 MLC nand에 올리는게 엄청나게 힘들더군요....ㅎㅎ
참, HW ECC를 썼습니다.
ubiblk에는 vfat을 올려봤는데, 훌륭합니다.......read속도는 훌륭합니다.
write는 MLC라...쩝...
