Hi All,
Broadcom BT4.0 module 0a5c:21e1 and 0a5c:21e3 need firmware
to setup(enable) at the first time we use.
We got the firmware and firmware uploader (brcm_patchram_plus_usb )
( user space tool ) from Broadcom ,the Licence is GPLv2,
would it possible that add those to bluez package?or any idea for this?
please correct me if i got any mistake,thanks.
Sincerely,
AL

Should firmware come to linux-firmware package?
Description: Firmware for Linux kernel drivers
This package provides firmware used by Linux kernel drivers.
Do not know about "firmware-loader", probably we need to use available tools.

Yes, I think so,
but 0a5c:21e1 and 0a5c:21e3 use btusb driver,
this firmware use at the first time to enable only,
and that firmware uploader need to use the bluez hci library.
So I guess add those to bluez would be better.

IMO the standard way is to use request_firmware like for ath3k:
request_firmware(&firmware, "ath3k-1.fw", &udev->dev)

Most probably that "firmware loader" might be implemented in module as for
other devices as it is usually just a sequence of HCI commands.
Have a look at other BCM modules in drivers/bluetooth/bcm*

can you post these firmware loader as a patch to this mailing list? Then
we can discuss on how to integrate it best.

Hi All,
Would anyone could give me help kindly?
I have sent the firmware uploader source code as a patch to this mailing list,
named: "How to add firmware uploader function to Bluez? (Broadcom
firmware uploader)"
There are Make file and source code "brcm_patchram_plus_usb.c" in this patch.
If you want to compiler this use "make" and need bluez-devel package
for bluetooth.h,
hci.h , and hci_lib.h..
I don't have enough knowledge about Bluez tool rules ,please correct
me if i got any mistake.
Sincerely,
AL
