MUX: Setting register HDIREN
PINMUX0 (0x01c40000) = 0x80000c1f -> 0x80010c1f
---MUX: initialized ATAEN---
MUX: Setting register ATAEN
PINMUX0 (0x01c40000) = 0x80010c1f -> 0x80030c1f
start to init davinci ide
hda: HTS541040G9AT00, ATA DISK drive
but when i fdisk /dev/hda ,there are some errors below:
