hi all
I got a problem while init the csr bluecore4 chip, my toolchain: bluez-3.12, dbus-1.0.2,kernel-2.6.10
#dbus-daemon --system
#hciattach ttyS0 bcsp
#hcid -f /opt/bluez/etc/bluetooth/hcid.conf
#hciconfig 
hci0:   Type: UART
        BD Address: 00:02:5B:00:A5:A5 ACL MTU: 310:10 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN 
        RX bytes:1128 acl:0 sco:0 events:23 errors:0
        TX bytes:706 acl:0 sco:0 commands:26 errors:0
above is always ok.
but csr chip need to set pskeys and warmreset,so I run bccmd
#bccmd warmreset
#hcitool scan
Scanning
Timeout...

This problem around me for a few days, I cant figure out why the csr chip doesnt work after warmreset.UART0 connect to csr chip, so I choose bcsp config in kernel and choose hci interface(here i am not sure about choosing hci or bcsp while run bccmd?), am i right?

 and what's the difference between H4 and bcsp, while both of them use uart interface?

Hello,

a few months back I encountered a similar problem. hciattach did not 
(and still does not) always succeed, and bccmd seems to have a problem 
using the BlueCore serial protocol (bcsp), possibly a race condition. 
That's why I have to use:

      /usr/sbin/hciattach /dev/ttymxc2 bcsp 57600 flow
      /usr/sbin/hciconfig hci0 up
      /usr/sbin/bccmd -t hci psload -r /usr/etc/bluetooth/apm6628BT-UART.psr
      killall hciattach
      /usr/sbin/hciattach /dev/ttymxc2 bcsp 115200 flow
      /usr/sbin/hciconfig hci0 up

Notice the bccmd -t hci, so you have to attach first using bcsp, then 
use bccmd with this hci in order to download the psr file (which will 
reset the BlueCore), then kill the hci and re-attach.

Hope this helps,
peter
