Hi all,
I�ve an MSI NetPC with an Winbond w83977af multi I/O chip onboard with IR.
My problem is the configuration. I always get I/= problems.
In the BIOS of the PC I set the winbond� s IR to 0x2e8 and IRQ 10.
The findchip tool tells me:
Found WINBOND W83977ATF Controller at 0x3f0, DevID=0x97, Rev. 116
SIR Base 0x180, FIR Base 0x180
IRQ = 11, DMA = 1
Enabled: yes, Suspended: no
UART compatible: yes
Half duplex delay = -1073743868 us
After booting I�m doing the following:
modprobe w83977af_ir
Result in /var/log/messages
Nov 1 17:38:34 linux kernel: IrDA (tm) Protocols for Linux-2.2 (Dag Brattli)
Nov 1 17:38:34 linux kernel: w83977af_init()
Nov 1 17:38:34 linux kernel: w83977af_open()
Nov 1 17:38:34 linux kernel: w83977af_probe()
Nov 1 17:38:34 linux kernel: w83977af_probe(), Wrong chip
version<7>w83977af_probe()
Nov 1 17:38:34 linux kernel: W83977AF (IR) driver loaded. Version: 0x11
Nov 1 17:38:34 linux kernel: w83977af_net_init()
Nov 1 17:38:34 linux kernel: IrDA: Registered device irda0
Then I�m doing: setserial /dev/ttyS2 port 0x2e8 irq 10
after that i�m doing irmanager -d 1
Result in /var/log/messages
Nov 1 17:38:58 linux irmanager: executing: 'echo 1 >
/proc/sys/net/irda/discovery'
Nov 1 17:38:58 linux irmanager: executing: 'echo linux >
/proc/sys/net/irda/devname'
After that the w83977af_ir module is sucssessfully loaded and also the irda
module. Sonect:
modprobe irtty
irattach /dev/ttyS2
Result in /var/log/messages
Nov 1 17:39:12 linux irattach: device=/dev/ttyS2
Nov 1 17:39:12 linux irattach: SIR device
Nov 1 17:39:12 linux irattach: tcsetattr: Input/output error
That� s it. It is not working
Can anybody tell me what I�m doing wrong?
Carsten
