全志调试总结

87 阅读 0 评论 58 点赞

我是靠谱客的博主不安星月，最近开发中收集的这篇文章主要介绍全志调试总结，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.下载工具

有window和Linux版本(可以支持ubuntu20.04)，用官网释放的工具就行，有些电脑要关掉安全启动usb驱动才能工作正常，也可以使用开源的usb驱动(https://github.com/linux-sunxi/sunxi-livesuite)。

2.下载方式

如下载工具的提示，注意需要接电池哦。

就是关机状态下，先按住任意按键(非电源键)，然后接usb，按几下电源键，然后松开所以按键。

还有就是强制下载方式，先接电池，烧录键(FEL)引脚然后对地，然后接usb。

3.编译

3.1 cd longan, ./build.sh(编译uboot,kernel等)

3.2 cd 源码根目录,Android标准编译方法

3.3 打包(pack)打包支持卡打印，不需要焊接串口线，有时比较方便

4.lcd调试

&lcd0 {
	lcd_used            = <1>;
	status              = "okay";
	lcd_driver_name     = "hx8279d_mipi_panel";
	lcd_backlight       = <50>;
	lcd_if              = <4>;

	lcd_x               = <1200>;
	lcd_y               = <1920>;
	lcd_width           = <135>;
	lcd_height          = <216>;
	lcd_dclk_freq       = <154>;

	lcd_hbp             = <38>;
	lcd_ht              = <1296>;
	lcd_hspw            = <20>;
	lcd_vbp             = <20>;
	lcd_vt              = <1980>;
	lcd_vspw            = <20>;


	lcd_pin_power = "dcdc1";


	lcd_power1 = "dcdc1";
	lcd_power2 = "dc1sw";

	lcd_gpio_0 = <&pio PD 22 1 0 3 1>;
	lcd_gpio_1 = <&pio PD 23 1 0 3 1>;
};

需要兼容多款屏幕，lcd0_1,lcd0_2,...，uboot通过sunxi_lcd_switch_compat_panel切换屏幕，如

sunxi_lcd_switch_compat_panel(sel, 1);/*switch to lcd0_1*/

sunxi_lcd_switch_compat_panel(sel, 2);/*switch to lcd0_2*/

注意下屏参，设计不够人性化，有时需要重新计算

lcd_dclk_freq=lcd_ht*lcd_vt*fps

lcd_hbp: hsync back porch(pixel) + hsync plus width(pixel);
lcd_ht: hsync total cycle(pixel)
lcd_vbp: vsync back porch(line) + vysnc plus width(line)
lcd_vt: vysnc total cycle(line)
lcd_hspw: hsync plus width(pixel)
lcd_vspw: vysnc plus width(pixel)

刷机第一次启动后，回记忆当前的屏幕，第二次启动直接初始化刷机后读到的屏幕，这样能加快启动速度，但如果换屏了，屏幕就不亮了，可以去掉该机制。

竖屏横显这块适配的比较好，配置相应的宏就行。

5.外置音频PA配置

dts有如下节点gpio-spk就是pa使能的节点

&codec {
...
        pa_level        = <0x01>;
        pa_msleep_time  = <0x78>;
        gpio-spk        = <&pio PH 6 GPIO_ACTIVE_HIGH>;
...
       
};

如果pa通过写寄存器使能，需要替换使能接口，如

longan/kernel/linux-5.4/sound/soc/sunxi/sun50iw10-codec.c(里控制gpio的函数替换成其他函数)

6.wifi和bt配置

官方有相应的适配文档，如Android_11_Wi-Fi_BT_开发指南.pdf

如device/softwinner/ceres/xxx/BoardConfig.mk

BOARD_WIFI_VENDOR := aic
BOARD_USR_WIFI    := aic8800
WIFI_DRIVER_MODULE_PATH := "/vendor/lib/modules/aic8800_fdrv.ko"
WIFI_DRIVER_MODULE_NAME := aic8800_fdrv
WIFI_DRIVER_MODULE_ARG  :=

# 2. Bluetooth Configuration
BOARD_BLUETOOTH_VENDOR    := aic
BOARD_HAVE_BLUETOOTH_NAME := aic8800
BOARD_BLUETOOTH_CONFIG_DIR :=  $(PRODUCT_PLATFORM_PATH)/common/wireless/bluetooth
# Must include after wifi/bt configuration
include device/softwinner/common/config/wireless/wireless_config.mk

关注下 include device/softwinner/common/config/wireless/wireless_config.mk

  else ifeq ($(BOARD_WIFI_VENDOR),aic)
        BOARD_WLAN_DEVICE           := aic
        BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_aic
        BOARD_HOSTAPD_PRIVATE_LIB   := lib_driver_cmd_aic
        BOARD_WIRELESS_PROPERTIES   += wifi.direct.interface=p2p-dev-wlan0
        -include hardware/aic/wlan/firmware/$(BOARD_USR_WIFI)/device-aic.mk

    else ifeq ($(BOARD_BLUETOOTH_VENDOR),aic)
        BOARD_HAVE_BLUETOOTH_AIC := true
        BOARD_CUSTOM_BT_CONFIG      := $(BOARD_CUSTOM_BT_CONFIG_TMP)
        -include hardware/aic/libbt/firmware/$(BOARD_HAVE_BLUETOOTH_NAME)/aic-bt.mk

BoardConfig.mk的修改就是为了编译hardware相应的文件

关注下这个定义

WIFI_DRIVER_MODULE_PATH := "/vendor/lib/modules/aic8800_fdrv.ko"
WIFI_DRIVER_MODULE_NAME := aic8800_fdrv

wifi_hal_common.cpp - OpenGrok cross reference for /frameworks/opt/net/wifi/libwifi_hal/wifi_hal_common.cpp

#ifdef WIFI_DRIVER_MODULE_PATH
static const char DRIVER_MODULE_NAME[] = WIFI_DRIVER_MODULE_NAME;
static const char DRIVER_MODULE_TAG[] = WIFI_DRIVER_MODULE_NAME " ";
static const char DRIVER_MODULE_PATH[] = WIFI_DRIVER_MODULE_PATH;
static const char DRIVER_MODULE_ARG[] = WIFI_DRIVER_MODULE_ARG;
static const char MODULE_FILE[] = "/proc/modules";
#endif

int wifi_load_driver() {

...
  if (insmod(DRIVER_MODULE_PATH, DRIVER_MODULE_ARG) < 0) return -1;
...
}

int wifi_unload_driver() {
...
#ifdef WIFI_DRIVER_MODULE_PATH
  if (rmmod(DRIVER_MODULE_NAME) == 0) {
...
}

打开/关闭 wifi回加载定义的wifi驱动。

wifi不工作时，可检查wifi模块电源，时钟，wifi模块驱动能否正常加载等。

7.sensor配置

7.1 sensor兼容

device/softwinner/ceres/xxx/input/sensor_modules.cfg
如
handle=ID_A
+path= mir3da.ko
+path= mc34xx.ko

7.2 sensor配置方向

device/softwinner/ceres/xxx/input/gsensor.cfg

8.调整串口打印等级

device/softwinner/ceres/ceres-xx/system/env.cfg
