Logo Change

Logo for customer Boot Logo U-boot [Android 4.2 ~ Android 4.4] 

 (1)  BSP support
 (2)  Convert the bmp file to hex value.
      Example : bmp file name is aaa.c
 (3)  Step1.
        Add aaa.o in board/freescale/common/Makefile
        Add aaa.c in board/freescale/common/
      Step2.
        Modify LCD setting in board/freescale/mx6q-rom-3420/mx6q_rom-3420.c
        Fill in correct timing parameters for customer panel (Phill provide parameter).
      Step3.
        Enable CONFIG_SPLASH_SCREEN config
        Set lvds_num to 0, because we use LVDS0 channel.

Boot Logo Android Frameworks [Android 4.2 ~ Android 4.4] 

 (1) Please rename your Logo file to "android-logo-mask.png"
 (2) Replace the logo image file

(1) In linux kernel

1. You need to add the mechanism for processing zero packets during transmission of “usb_wwan.c” file under “[KERNEL]/drivers/usb/serial”. 

You need to add the following statements to the “usb_wwan_setup_urb” function, as shown below: 

/* Helper functions used by usb_wwan_setup_urbs */
static struct urb *usb_wwan_setup_urb(struct usb_serial *serial, int endpoint,
                      int dir, void *ctx, char *buf, int len,
                      void (*callback) (struct urb *))
{
    struct urb *urb;

    if (endpoint == -1)
        return NULL;    /* endpoint not needed */

    urb = usb_alloc_urb(0, GFP_KERNEL);    /* No ISO */
    if (urb == NULL) {
        dbg("%s: alloc for endpoint %d failed.", __func__, endpoint);
        return NULL;
    }

    /* Fill URB using supplied data. */
    usb_fill_bulk_urb(urb, serial->dev,
              usb_sndbulkpipe(serial->dev, endpoint) | dir,
              buf, len, callback, ctx);

<span style="color:#B22222;">    /*Quectel PRODEUCTS*/
    if (dir == USB_DIR_OUT) {
        struct usb_device_descriptor *desc = &serial->dev->descriptor;
        if (desc->idVendor == 0x05C6 && (desc->idProduct == 0x9003 
            || desc->idProduct == 0x9090 
            || desc->idProduct == 0x9215)) {
                urb->transfer_flags |= URB_ZERO_PACKET;
        }
    }</span>
    return urb;
}


2.  Add UC15/UC20/EC20's Vendor ID and Product ID in "option_ids[]" in the file "drivers/usb/serial/option.c": 

static const struct usb_device_id option_ids[] = {
<span style="color:#B22222;">#start // Added by Quectel
{ USB_DEVICE(0x05C6, 0x9090) }, //For UC15
{ USB_DEVICE(0x05C6, 0x9003) }, //For UC20
{ USB_DEVICE(0x05C6, 0x9215) }, //For EC20
#end</span>

(2) You need to configure the kernel to support PPP dial up. Check your menuconfig.    Ref: Quectel_Android_RIL_Driver_User_Guide_V1.3.pdf 

  ps : In android 4.4.2. we already enable ppp config and USB driver for GSM/CDMA modems.

(3)  Modify init.rc.  In android\device\fsl\imx6\etc\init.rc. 

  on boot
    setprop rild.libargs "-d /dev/ttyUSB2"

  service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so
      class main
      socket rild stream 660 root radio
      socket rild-debug stream 660 radio system
      user root
      group radio cache inet misc audio sdcard_rw log

(4)  tar zxvf reference-ril.tar.gz to android/hardware/ril/

(5)  Mark chat.c module form AOSP  (android\external\ppp\pppd\Android.mk) 

# Force sizeof(enum)=4
LOCAL_CFLAGS := -fno-short-enums -DANDROID_CHANGES -DCHAPMS=1 -DMPPE=1 -Iexternal/openssl/include

LOCAL_MODULE:= pppd
LOCAL_MODULE_TAGS := optional
include $(BUILD_EXECUTABLE)

<span style="color:#B22222;">#include $(CLEAR_VARS)
#LOCAL_SRC_FILES := chat.c
#LOCAL_SHARED_LIBRARIES := libcutils
#LOCAL_MODULE := chat
#LOCAL_MODULE_TAGS := optional
#include $(BUILD_EXECUTABLE)</span>
