[irda-users] FIR (mxc_ir) driver is not detacting other IrDA device

[Alim A. <ali...@gm...>]

Hi
I am using mxc_ir FIR driver for my ARM (iMX31) based board. but i am facing
few problem, like when i am doing
# ifconfig irda0 up
and # irattach irda0 -s
i am getting the below error please have a look on the log below:
--------------------log
start------------------------------------------------------------
kernel: Debug...inside mxc_irda_start()
Jan  1 00:13:53 debian kernel: Debug...inside mxc_irda_startup
Jan  1 00:14:13 debian irattach: executing: '/sbin/modprobe irda0'
Jan  1 00:14:13 debian kernel: kobject_register failed for mxc_irda (-17)
Jan  1 00:14:13 debian irattach: executing: 'echo debian >
/proc/sys/net/irda/devname'
Jan  1 00:14:13 debian irattach: executing: 'echo 1 >
/proc/sys/net/irda/discovery'
Jan  1 00:14:13 debian irattach: Starting device irda0
-------------------------------log
end---------------------------------------------------------
you can see that "kobject_register failed for mxc_irda (-17)" failed.
and irdadump do not give me any result too.

please suggest me what could me the reason for this?
Also is any UART is needed in case i am using FIR (SIR is working fine on
the board).
waiting for your reply.
