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 Machine check in kernel mode.

The project deadline is near ... so I ask here ... can anyone helps me or give me some clues? Thanks all
