Hi all,
our company has serval MS-6204 NetPc's with IRDA from mirco-star and have problems
to get irattach working. The machine runs debian with latest 2.2.15 pacthed
with patch-irda2.2.15pre20 and latest irda-utils 0.9.10. All Irdastuff compiled
with debug and as modules.
I enabled irda on com2 with io=2f8, irq=3 and dma=1 in the bios.
Under linux /dev/ttyS1 is confed with setserial /dev/ttyS1 uart none
findchip says the following:
Probing for EFER at 0x03f0 ...
hefras = 0x00
EFER seems to be probed at 0x03f0
chip id = 0x97, revision = 0x74
Device Revision 0x97 : W83977ATF is detected!
TX DMA is inactive, or single DMA mode
RX->TX Turn around delay(4 char time) is enabled
TX->RX Turn around delay(4 char time) is disabled
Bank selection is disabled(CRF0 = 0x04).
Found WINBOND W83977ATF Controller at 0x3f0, DevID=0x97, Rev. 116
SIR Base 0x2f8, FIR Base 0x2f8
IRQ = 3, DMA = 1
Enabled: no, Suspended: no
UART compatible: yes
Half duplex delay = 1073819856 us
then I modprobe irda, which goes fine,
modprobe w83977af_ir io=2f8 irq=3, i have to do that because only the
module will set irq to 11 and io to 1f8. I look up in the source code
and find out that this are the standard values for the variables.
after modprobe the syslog says the following:
un 23 08:15:27 razor kernel: w83977af_init()
Jun 23 08:15:27 razor kernel: w83977af_open()
Jun 23 08:15:27 razor kernel: w83977af_probe()
Jun 23 08:15:27 razor kernel: w83977af_probe(), Wrong chip version<7>w83977af_probe()
(maybee this where something goes wrong)
Jun 23 08:15:27 razor kernel: W83977AF (IR) driver loaded. Version: 0x11
Jun 23 08:15:27 razor kernel: w83977af_net_init()
Jun 23 08:15:27 razor kernel: IrDA: Registered device irda0
then findchip says:
Probing for EFER at 0x03f0 ...
hefras = 0x00
EFER seems to be probed at 0x03f0
chip id = 0x97, revision = 0x74
Device Revision 0x97 : W83977ATF is detected!
TX DMA is inactive, or single DMA mode
RX->TX Turn around delay(4 char time) is disabled
TX->RX Turn around delay(4 char time) is disabled
Bank selection si enabled.
Found WINBOND W83977ATF Controller at 0x3f0, DevID=0x97, Rev. 116

IRQ = 3, DMA = 1
Enabled: yes, Suspended: no
UART compatible: yes
Half duplex delay = 1073819856 us
Now I can bring up irda0 with: ifconfig irda0 up
Then I modprobe ircomm and ircomm-tty and syslog shows:
un 23 08:16:41 razor kernel: w83977af_net_open()
Jun 23 08:16:41 razor kernel: irlap_change_speed(), setting speed to 9600
Jun 23 08:16:59 razor kernel: IrCOMM protocol (Dag Brattli)
If I try now irattach /dev/ttyS1 I got:
Jun 23 08:17:18 razor irattach: tcsetattr: Input/output error
In the Motherboardmanual and on the homepage are no Inforamtion about the chipset.
Thats why I opened the machine and I took a look a my self, but I only found
the alphanumerics HP1100 on the IR-LED.
Now my Question are, have some one the same problem and a solutioni?
If no I will ask micro-star for the chipset name and the spezification.
Maybe do a patch, but I am not such a good coder
