[ltp] Linux, kernel 2.4.22-ac4/2.4.23 and IRDA
Fri, 12 Dec 2003 06:27:36 +1100
Hmmmm... ok... so I've remapped some stuff using ps2.exe...
Now I have:
[root@localhost etc]# findchip -v
Found NSC PC87338 Controller at 0x2e, DevID=0x0b, Rev. 2
SIR Base 0x2f8, FIR Base 0x2f8
IRQ = 5, DMA = 3
Enabled: no, Suspended: no
UART compatible: yes
Half duplex delay = 0 us
No sure why it still says that 'Enabled: no' - I enabled it using
ps2.exe - maybe something in the kernel is disabling it? Anyhow, the
serial port is on COM1 with the normal IRQ, modem is on COM4 with normal
settings, and IR is now on COM2 with IRQ5... All seems to look ok here:
[root@localhost etc]# cat /proc/interrupts
0: 54272 XT-PIC timer
1: 1639 XT-PIC keyboard
2: 0 XT-PIC cascade
3: 600 XT-PIC orinoco_cs
8: 1 XT-PIC rtc
11: 533 XT-PIC cs46xx, Texas Instruments PCI1450,
Texas Instruments PCI1450 (#2), usb-uhci
12: 12406 XT-PIC PS/2 Mouse
14: 10362 XT-PIC ide0
15: 3651 XT-PIC ide1
in /etc/modules.conf, I've put:
options nsc-ircc io=0x2f8 irq=5 dma=3 dongle_id=0x09
however, when I insmod nsc-ircc, I still get the following in the
Dec 12 06:23:13 localhost kernel: nsc-ircc, Found chip at base=0x02e
Dec 12 06:23:13 localhost kernel: nsc-ircc, Wrong chip version ff
Do I need to run tpctl to enable the IR port in linux? or does the
'Enabled: no' mean something else with the findchip program?
I don't really care about high-speed usage... I'm attempting to sync my
mobile phone addressbook etc with Evolution over the IR port, so 115200
is fine. Does this mean I only need irtty? something else?
I haven't really been able to find a straight forward guide into doing
this, so I'm patching pieces together from various sources (ie google
searches) so I apologise if I have some basic concept wrong..
