[Bluez-users] Pretec and Ambicom BT2000E driver

[Bluez-users] Pretec and Ambicom BT2000E driver

[Pavel Ruzicka]

Hello,

yesterday somebody talks about BT2000E CF card.
I have Pretec BT2000E CF card.
I found new version of alternative driver which probably fix resume problems 
and 2.6 kernel compiling.
I found changelog here:

Best regards,

Pavel Ruzicka

I know that driver and I really thought of including it, but the best
way is to make it working through serial_cs and hci_uart/hciattach. Once
this is solved every card with a 16C950 UART will work and not only the
two with an Ericsson chip on it.

Marcel

My Ambicom card is an ericsson chipset and I can't seem to get it to work. :(

Were you able to get this to work in 2.6? I can't seem to find out how to
compile it.

Today I make some experiments with it.
I have Zaurus SL-C860 with CackoRom kernel 2.4.18...

I edit configuration. After inserting BT2000E CF card is loaded serial_cs
kernel module.
DMESG: ttyS03 at port 0xf60002f8 (irq = 39) is a 16C950/954

# hciattach 10 ttyS3 ericsson 115200
# hciconfig hci0 up
Can't init device hci0. Connection timed out(110)

I've tried several combination with hciattach command with speed from 9600 to 
460800, flow enabled/disabled but without success.

Do you have some idea?

Do you know right parameters for hciattach?

There are some more useful informations:
# cat /proc/tty/driver/serial
serinfo:1.0 driver:5.05c revision:2001-07-08
0: uart:16C950/954 port:F60002F8 irq:39 baud:115200 tx:139 rx:21 fe:6 brk:11

1: uart:unknown port:0 irq:0
2: uart:unknown port:0 irq:0
3: uart:unknown port:0 irq:0

# cat /proc/tty/drivers
serial_cpu           /dev/cua        5   64-66 serial:callout
serial_cpu           /dev/ttyS       4   64-66 serial
serial               /dev/cua        5   67-70 serial:callout
serial               /dev/ttyS       4   67-70 serial

# ls -l /dev/ttyS3
crw-------    1 zaurus   root       4,  67 Apr 10 21:58 /dev/ttyS3

I have few more questions.
In dmesg I see: ttyS03... Why not ttyS3?

When I make"rmmod serial_cs"
I see in dmesg this: tty03 unloaded.
Why tty03 and not ttyS3?

I'am a little confused ;-)

This cards works now with bt2000e_cs.o but sometimes my Zaurus freezes when 
removing card...

What kernel does it work on? I'm trying to figure out HOW to compile it!

I use this card on Sharp Zaurus SL-C860, which is ARM architecture.
Kernel 2.4.18-rmk7-pxa3-embedix. There are not possible to use newer
kernel.
I use precompiled driver.
I don't know, how to compile driver. Maybe write to kernel tree and edit 
Makefile /usr/src/linux/drivers/bluetooth.
But I'am not kernel expert.

Best regards,

Pavel Ruzicka

Hi Gene,

I don't got any progress so far and from a first code review I also
can't take the bt2000e driver into the kernel, because it would oops.

> I have some of these and would like them to work.

Go ahead and try. Every patch to make this working is welcome.

Regards

Marcel
