Dear all,
I am a student from Hong Kong. Now I am doing a project about enabling a Bluetooth PCMCIA card (Billionton PCBTC1A-B) in a custom MPC860PC.
(The custom MPC860 system is constructed by a MPC860 Processor Card and a custom made PCB to adding a PCMCIA interface to the processor Card.)
Now my stage is: the LINUX (Linux Kernel 2.4.25 from ELDK 3.1 for powerpc) can recognise the card by cardctl, and here are the screen dump:
/ # cardctl ident
Socket 0:
product info: "PCMCIA", "Bluetooth Card", "", ""
manfid: 0x0279, 0x950b
function: 2 (serial)
/ # cardctl status
Socket 0:
5V 16-bit PC Card
function 0: [ready], [bat dead], [bat low]
/ # cardctl info
PRODID_1="PCMCIA"
PRODID_2="Bluetooth Card"
PRODID_3=""
PRODID_4=""
MANFID=0279,950b
FUNCID=2
/ # cardctl config
Socket 0:
Vcc 5.0V Vpp1 5.0V Vpp2 5.0V
but after I load all the modules needed (should be these?)
/ # lsmod
Module Size Used by Not tainted
hci_uart 14836 0 (unused)
l2cap 22956 0 (unused)
bluez 43856 0 [hci_uart l2cap]
ds 8060 0
m8xx_pcmcia 5164 1
pcmcia_core 39520 0 [ds m8xx_pcmcia]
my bluetooth still cannot get working ...
then I try to insert "serial_cs" as my bluetooth card is a uart base card. but some message given out:
/ # insmod serial_cs
Using /lib/modules/2.4.25/serial_cs.o
insmod: unresolved symbol unregister_serial
insmod: unresolved symbol register_serial
so I realize that I should also insert "serial.o" into the linux, but crashes ...
/ # insmod serial
Using /lib/modules/2.4.25/serial.o
Serial driver version 5.05c (2001-07-08) with MANY_PORTS SHARE_IRQ enabled

I only knows when i insert the serial.o, this driver will try to access the standard uart which is not available in my system (my system only has one uart by SMC1), then the system will crash each time the driver wants to access the registers does not available ...
The project deadline is near ... so I ask here ...
can anyone helps me or give me some clues?
Thanks all
Best regards,
Chung

You should take a look for instance how 8349 does this job (arch/ppc/syslib/ppc83xx_setup.c) - it also has "standard" UART, but some stuff needs to be set up
prior to serial.o. Of course that is not complete solution for your case, just a hint...

Thanks for your hint. But the file is just for Linux Kernel Version 2.6, is this also OK for me? (I am using a 2.4 kernel)
But I doubt that same technique can be applied since the Bluetooth should only be enabled when I loaded the pcmcia drivers (pcmcia_core.o, m8xx_pcmcia.o and ds.o), so ....
how can I pre-set some settings during boot-time that I have not yet insert the pcmcia modules into the kernel?
Also the last thing is, since there is not "hotplug" in my system and resources allocation is different from standard PCs, so I cannot let my embedded system to auto-detect a standard uart has been added during the PCMCIA bluetooth card is plugged in (while standard PC will)
or can anybody tell me that how can I realize hotplug in my system? (is this can be worked out?)
Thanks

The way I know is to configure serial stuff before serial.o insmoded, so it could get right offsets and other stuff.
Look at the serial code, and if the only way to do mentioned is to configure it compile-time, than you'll have to implement
something. But I beleive another serial PCMCIA exist, that does it right way.

I don't know hotplug stuff very well, but I guess to find the way to solve your problem
will be easier.
