Hi Loic,
Many thanks for your suggestion!
I hadn't used hciattach on BCM4354A2 hardware before, so I tried it
out today and found that it couldn't yield better result than
brcm_patchram_plus program. As a matter of fact, after the firmware
patchfile is downloaded the HCI_Reset command needs very likely to be
re-sent again otherwise it simply blocks on reading relevant HCI_Event
packet until times out in the default 10 seconds. Once I resent this
command by capturing the SIGALRM in 4 seconds, the hci0 can be
enabled.
However, I still found logs that an extra 0x00 byte was skipped over
(by my workaround patch) for some HCI_Event packet (otherwise lots of
HCI commands would time out because this extra 0x00 byte would fail
hci_reassembly()) and start discovery also failed by 0x0C error code
(command disallowed).
I am using hciattach bcm43xx in the way of:
{ "bcm43xx", 0x0000, 0x0000, HCI_UART_H4, 115200, 4000000,
FLOW_CTL, DISABLE_PM, "40:40:a7:a6:a5:c1", bcm43xx, NULL },
/ # ./hciattach -n /dev/ttyHS0 bcm43xx
bcm43xx_init
Set Controller clock (1)
Set Controller UART speed to 4000000 bit/s
Flashed firmware /etc/firmware/BCM4354A2.hcd
Not received hci event for reset command, reset again (printed by
SIGALRM handler to send hci reset command in 4 sec)
Set BDADDR UART: 40:40:a7:a6:a5:c1
Set Controller clock (1)
Set Controller UART speed to 4000000 bit/s
Device setup complete
Cheers,
Harry
