** Name: brcm_patchram_plus.c
|
**
|
** Description: This program downloads a patchram files in the HCD format
|
** to Broadcom Bluetooth based silicon and combo chips and
|
** and other utility functions.
|
**
|
** It can be invoked from the command line in the form
|
** <-d> to print a debug log
|
** <--patchram patchram_file>
|
** <--baudrate baud_rate>
|
** <--bd_addr bd_address>
|
** <--enable_lpm>
|
** <--enable_hci>
|
** <--use_baudrate_for_download>
|
** <--scopcm=sco_routing,pcm_interface_rate,frame_type,
|
** sync_mode,clock_mode,lsb_first,fill_bits,
|
** fill_method,fill_num,right_justify>
|
**
|
** Where
|
**
|
** sco_routing is 0 for PCM, 1 for Transport,
|
** 2 for Codec and 3 for I2S,
|
**
|
** pcm_interface_rate is 0 for 128KBps, 1 for
|
** 256 KBps, 2 for 512KBps, 3 for 1024KBps,
|
** and 4 for 2048Kbps,
|
**
|
** frame_type is 0 for short and 1 for long,
|
**
|
** sync_mode is 0 for slave and 1 for master,
|
**
|
** clock_mode is 0 for slabe and 1 for master,
|
**
|
** lsb_first is 0 for false aand 1 for true,
|
**
|
** fill_bits is the value in decimal for unused bits,
|
**
|
** fill_method is 0 for 0's and 1 for 1's, 2 for
|
** signed and 3 for programmable,
|
**
|
** fill_num is the number or bits to fill,
|
**
|
** right_justify is 0 for false and 1 for true
|
**
|
** <--i2s=i2s_enable,is_master,sample_rate,clock_rate>
|
**
|
** Where
|
**
|
** i2s_enable is 0 for disable and 1 for enable,
|
**
|
** is_master is 0 for slave and 1 for master,
|
**
|
** sample_rate is 0 for 8KHz, 1 for 16Khz and
|
** 2 for 4 KHz,
|
**
|
** clock_rate is 0 for 128KHz, 1 for 256KHz, 3 for
|
** 1024 KHz and 4 for 2048 KHz.
|
**
|
** <--no2bytes skips waiting for two byte confirmation
|
** before starting patchram download. Newer chips
|
** do not generate these two bytes.>
|
** <--tosleep=number of microsseconds to sleep before
|
** patchram download begins.>
|
** uart_device_name
|
**
|
** For example:
|
**
|
** brcm_patchram_plus -d --patchram \
|
** BCM2045B2_002.002.011.0348.0349.hcd /dev/ttyHS0
|
**
|
** It will return 0 for success and a number greater than 0
|
** for any errors.
|
**
|
** For Android, this program invoked using a
|
** "system(2)" call from the beginning of the bt_enable
|
** function inside the file
|
** system/bluetooth/bluedroid/bluetooth.c.
|
**
|
** If the Android system property "ro.bt.bcm_bdaddr_path" is
|
** set, then the bd_addr will be read from this path.
|
** This is overridden by --bd_addr on the command line.
|
