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.
 
Regards
