Hi all, I know this thread is old but i am desperate. I have a gumstix from www.gumstix.com, linux 2.6 ARM etc.

I have put an Audiovox RT-8000 in it but it is not going to work without a fight so I need your help. I will not bore you with too much gorry detail which is not required because I have just found the serial_cs.o module here, the problem is I try to load the module and it says

"insmod: error inserting './serial_cs.o': -1 Invalid module format"

The irq allocation for the card is totally messed up so I really need this patch.

cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16C950/954 port:C4860400 irq:49 tx:169 rx:0 CTS
1: uart:unknown port:00000000 irq:0
2: uart:unknown port:00000000 irq:0
3: uart:unknown port:00000000 irq:0

# cat /proc/tty/drivers
/dev/tty /dev/tty 5 0 system:/dev/tty
/dev/console /dev/console 5 1 system:console
/dev/ptmx /dev/ptmx 5 2 system
serial /dev/ttyS 4 64-67 serial
PXA serial /dev/ttySA 4 68-71 serial
pty_slave /dev/pts 136 0-1048575 pty:slave
pty_master /dev/ptm 128 0-1048575 pty:master

No 49 irq is used by the serial :-(
seems like 8250.ko should be patched :-(

# cat /proc/interrupts
CPU0
0: 44 SC HWUART
4: 0 SC pxa2xx_udc
18: 0 SC DMA
19: 68485 SC PXA Timer Tick
27: 0 GPIO CF0 nSTSCHG
34: 0 GPIO CF0 nCD
58: 0 GPIO pxa2xx_udc
59: 1778 GPIO eth0
Err: 0

I am a noob having a love/hate relationship with linux at the moment, can someone guide me to the light?

Thanks
Chris

I think that the seerial_cs.o module you got from somewhere is for kernel 2.4, thus completely unusable under 2.6.

maybe if using 2.6, the serial_cs.ko (the module naming in 2.6 is .ko) that is already with the distribution you are using could work.

1) Do you have a serial_cs module from the same place you got 2.6 kernel? Can you modprobe that module ?

If so, I'd suggest to go ahead and after, send the setserial command.

yeah, I would agree that it sounds like a module mismatch. Be sure to use the same kernel source throughout and also to make sure the kernel versioning is correct in the main Makefile.

ok so it is all down to 8250.ko module, it needs to be modified. oh my god this is hard work for me, I am dumbass!

it needs support for irq49 or something like that, how does a module get compiled? Where is the source

Hi,

I'd suggest

1) ask someone in a gumstix forum o mailing list to have it compiled for you

2) install a virtual machine with all the gumstix development tools installed, and go compile yourself ...

The source is probably somewhere the linux 2.6 modules sources.

This doesnt work for me, but I found this article useful:

http://tuxmobil.org/pcmcia_cf_anycom_gprs.html

... and now I am connected

I dont know what change take effect, but this:

CODE
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/provider"
defaultroute
/dev/ttyS0
115200
nocrtscts
lock
noipdefault
debug
user fasel



and this:

CODE
ABORT BUSY
ABORT "NO CARRIER"
ABORT VOICE
ABORT "NO DIALTONE"
"" ATZ
OK AT+CPIN="<PIN>"
OK AT+CGDCONT=1,"IP","<APN>"
OK ATDT*99***1#
'CONNECT' '\c'
'TIMEOUT' '5'


are WORKING on SL-C1000 (pdaXii13 build5.4.9 "Sally" with kkazakov13 libraries and some from pdaXii13v2)

But thanx anyway, because this post inspired me and was the first thing when I was looking where to start.

Hope my post help anybody with same trouble ;-)
