I've been trying to get IrDA working under DSL - I've managed to make things work on the same system under DSL-N - but have hit a problem.Things go well to start with:
# apt-get install setserial
# setserial /dev/ttyS1 uart none
# modprobe smc-ircc ircc_irq=3 ircc_dma=3 ircc_sir=0x2f8 ircc_fir=0x280
# dmesg
...
Overriding FIR address 0x0280
Overriding SIR address 0x02f8
SMC IrDA Controller found
IrCC version 2.0, firport 0x280, sirport 0x2f8 dma=3, irq=3
IrDA: Registered device irda0
# apt-get install irda-utils
Then, under DSL-N (and according to Google under 2.4.x was well) the next command is:
# irattach irda0 -s
However, DSL really, really doesn't like this and hangs with the caps lock/scroll lock lights flashing - in all time I've been blundering around in DSL, I never managed to do this before
The /etc/modutils/irda-utils file contains the line "alias irda0 smc-ircc" so I tried the following:
# mknod /dev/irda0 c 160 0 [from Google]
# irattach irda0 -s
Which also results in DSL hanging
"ls /dev/ir* turns up ircomm0, ircomm1, irlpt0, irlpt1 & irnet and searching on irda0 using gtkfind from / and all subdirectories finds nothing.
Does anyone have an idea what the problem might be?

Though I have no experience with IrDA, perhaps you should compile these tools just to be thorough (since you're probably familiar with it now
)

"...perhaps you should compile these tools just to be thorough"What tools do you mean?

Instead of using apt-get that is...If no other help/info else shows up I usually end up trying everything like that.

So, after a brief pause, I had another look at this - it seems it's possible to start an irda device without irda-utils:| Code Sample |
| $ sudo ln -s /dev/ttyS1 /dev/irda0 $ sudo insmod irda $ sudo ifconfig irda0 up $ ifconfig irda0 irda0 Link encap:IrLAP HWaddr a7:c5:1c:32 UP RUNNING NOARP MTU:2048 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:8 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) # echo -n 1 >/proc/sys/net/irda/discovery [note terminal as root] $ cat /proc/net/irda/discovery IrLMP: Discovery log: nickname: P900, hint: 0x9325, saddr: 0xa7c51c32, daddr: 0x1770890c |
If I disable the serial port emulation and try to use the ir port directly:
| Code Sample |
| $ sudo setserial /dev/ttyS1 UART none $ sudo rmmod serial $ sudo mknod -m 664 /dev/irda0 c 160 0 $ sudo insmod irda $ sudo insmod irport io=0x2f8 irq=3 $ dmesg | grep irda0 IrDA: Registered device irda0 $ sudo ifconfig irda0 up $ ifconfig irda0 irda0 Link encap:IrLAP HWaddr bb:59:77:82 UP RUNNING NOARP MTU:2048 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:1 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:8 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:3 Base address:0x2f8 # sudo echo -n 1 > /proc/sys/net/irda/discovery |
Note that this also happens if I replace "$ sudo mknod -m 664 /dev/irda0 c 160 0"with "$ sudo ln -s /dev/ircomm0 /dev/irda0"
Does anybody have an idea what the problem might be?
Edit: I should maybe add that the reason behind this is that obexftp will not work when the ir port emulates a serial port so I would like to get the full ir port functionality and speed (4Mbits vs 115,000).
