hi all,
I have connect a sata harddisk to dm385 through si13132 that convert sata bus to pcie bus.
I have already reference the "TI81XX_PSP_PCI_Express_Root_Complex_Driver_User_Guide.pdf" .
In Taking care of PERSTn section,there are a note: Note: This section including sub-sections do not apply to TI814X/TI813X.
so don't care of PERSTn in dm385?
Then i make menuconfig in kernel directory and configure:
[*] PCI support
[*] Message Signaled Interrupts (MSI and MSI-X)
'''[*] PCI Debugging'''
< > PCI Stub driver
[ ] PCI IOV support
,when boot the kernel ,the message show:
......
registered ti81xx_vpss device
registered ti81xx_vidout device
registered ti81xx on-chip HDMI device
registered ti81xx_fb device
PWM0 init success.
PWM1 init success.
ti81xx_pcie: Invoking PCI BIOS...
ti81xx_pcie: Setting up Host Controller...
ti81xx_pcie: Register base mapped @0xc5820000
ti81xx_pcie: forcing link width - x1
ti81xx_pcie: Starting PCI scan...nr=0
PCI: bus0: Fast back to back transfers enabled
ti81xx_pcie: PCI scan done.
bio: create slab <bio-0> at 0
vgaarb: loaded
SCSI subsystem initialized
......
in filesystem,
ls /sys/bus/pci/devices/ (result :can't get anything)
what's next step should i do to running sata hard disk as a normal storage device? (convert sata bus to pcie bus by si13132)
have a more detailed documentation？
thanks!
