Dear LinuxIR people,
I've been using the Linux IR stuff for a couple of years, so I'm no newbie.
At the moment, a friend and I are trying to write the 4Mbps support for the
Arm SA1100 into the arm kernel, but are runnung into problems when using FIR
speeds.
Here's the deal.
We've got the following to test with:
*Sony Viao 505Fx with SMC-IRCC controller (sadly running W2K) - This should
be a working FIR setup.
*Sony Viao Z600RE with NSC-IRCC controller (Running latest bleeding edge
everything, including Jean Tourrilhes' patch from Tue, 2 Jan)
/etc/modules.conf
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
options nsc-ircc dongle_id=0x09
alias irda0 nsc-ircc
*Compaq Ipaq running Ipaq-linux 0.19 with new irda utils, and latest
bleeding edge kernel, and the sa1100_ir driver from Russel King, to which
we're trying to add FIR support).
*Psion 5 MX - Hardly matters, it's only does SIR speeds.
We have SIR speeds working just great with all of the above, but can't get
FIR working between any of the kit above. In particular, what I expect to
work is FIR between the two Viao machines. The NSC driver is listed on the
Linux IR status page as working at FIR speed, and the W2K driver has worked
for me at FIR speed in the past, but I just get the following....
irlap_change_speed(), setting speed to 9600
protocol 1700 is buggy, dev irda0
irlap_state_ndm(), media busy!
irlap_change_speed(), setting speed to 4000000
nsc_ircc_change_speed(), handling baud of 4000000
IrLAP, no activity on link!
irlap_change_speed(), setting speed to 9600
protocol 1700 is buggy, dev irda0
As soon as I go into FIR speeds with the NSC driver or the SA1100_ir driver,
I stop recieving packets.
Has anyone had success with the nsc-ircc driver at FIR speeds?
Has anyone had success with any drivers at FIR speeds?
Has anyone got any suggestions?
Does anyone want to debug my code?
Help!
Jim
