This page guides through the kernel configuration process to enable support for a ANYCOM Blue CF-300 Bluetooth CompactFlash card.

This driver is targeted to be used with the cf-ide-nand

Enabling Kernel PCMCIA Support

  • During kernel Configuration Enable
    Bus options (PCI, PCMCIA, EISA, MCA, ISA)  --->
       PCCARD (PCMCIA/CardBus) support  --->

<*> PCCard (PCMCIA/CardBus) support
[ ]   Enable PCCARD debugging
<*>   16-bit PCMCIA support
[*]     Load CIS updates from userspace (EXPERIMENTAL)
[*]     PCMCIA control ioctl (obsolete)
---   PC-card bridges
<*>   Blackfin CompactFlash PCMCIA Driver
  • External Bus Interface Unit EBIU Configuration

Enable maximum wait states (0xFFC3) for the memory bank the interface is connected to (/AMS3).

  • Adjusting System Clock Speed

Depending on the inserted cards, System Clock SCLK must not exceed maximum timing requirements.

Bluetooth Support

Enable Bluetooth Support and Bluecard PC Card HCI driver

[*] Networking support
      Networking options  --->
[ ]   Amateur Radio support  --->
< >   IrDA (infrared) subsystem support  --->
<*>   Bluetooth subsystem support  --->
< >   Generic IEEE 802.11 Networking Stack

--- Bluetooth subsystem support
