Hello,
I'm new to this list and wish to get help from it since I'm currently
developing a switch box based on mpc8245, the kernel I'm using is 2.6.14.
Now I'm trying to bring up the I2C controller then I2C devices. Is fsl-i2c
the driver for I2C controller of MPC8245? I enabled that driver and it was
installed, but there is no any device found. Why is it like that? Following
are the dump from sysfs.
/ # systool -b platform -d
Bus = "platform"
Device = "serial8250"
Device = "serial8250.0"
Device = "serial8250.1"
/ # systool -b platform -D
Bus = "platform"
Driver = "fsl-i2c"
Driver = "serial8250"
Devices using "serial8250" are:
Device = "serial8250"
Device = "serial8250.0"
Device = "serial8250.1"
In the booting sequence, I got following error message:
PCI: Probing PCI hardware
PCI: Cannot allocate resource region 1 of device 0000:00:00.0
fsl-i2c.1: failed to claim resource 0
unable to register device 0
fsl-dma.0: failed to claim resource 0
unable to register device 1
fsl-dma.1: failed to claim resource 0
unable to register device 2
Does this error make device undetected? What might be the reason for above
errors? I'd appreciate if you could shed some lights.
Regards,
- Reeve
