Enable a PCMCIA Bluetooth card in custom MPC860 system

[Lo Chun Chung]

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
