SSD202 Linux开发日志记录

一、挂载U盘

SDK默认自动加载USB存储模块，但没有自动挂载，插上U盘后识别sda

mount /dev/sda /mnt/

即可在/mnt查看U盘文件

二、make & make menuconfig提示失败

kernel
make & make menuconfig 提示错误
打开新终端后输入

declare -x ARCH="arm"
declare -x CROSS_COMPILE="arm-linux-gnueabihf-"

三、CH340 USB转串口

→ Device Drivers → USB support → USB Serial Converter support

可找到对应的驱动模块加载编译即可

四、芯片引脚编号

SSD201 HW Checklist V10(1).xlsx
文件可找到芯片引脚编号与驱动序号对照表

用于用户空间操作GPIO

五、SDK默认只有/customer目录可读写，修改为根目录可以读写

在project/configs/current.configs文件中找到IMAGE_CONFIG对应的分区文件

修改ro为rw
六、GPIO复用模式

在有些文档中能找到GPIO复用功能说明，例如I2C的GPIO

七、生成disp_init程序，如需视频显示，在disp_init程序中加入

stDispPubAttr.eIntfType = E_MI_DISP_INTF_LCD;
stDispPubAttr.eIntfSync = E_MI_DISP_OUTPUT_USER;

八、用户空间读写寄存器

/config/riu_w bank reg value
/config/riu_r band reg

九、屏参文件转换

屏厂家提供的屏参文件为右边，需转换为左边的数组格式
DCS_Short_Write_1P 写一个字节
DCS_Short_Write_1P 写两个字节
DCS_Long_Write_FIFO 写一串命令字节流

左边格式，一行为一条指令，第一个为地址，第二个为长度，第三个为需写入数据
在屏初始化命令最后需要结束符
FLAG_END_OF_TABLE, FLAG_END_OF_TABLE,

屏参数主要修改以下几个，可在屏数据手册找到

十、修改各分区大小

我的板子使用spiand.ubifs.p2.partition.config这个文件
/project/image/configs/i2m/spiand.ubifs.p2.partition.config

十一、烧写不成，查看是否支持当前FLASH

project/image/output/images/boot/SPINANDINFO.sni
使用工具打开，查看是否支持当前Flash，没有需添加

十二、添加HY4635触屏驱动

→ System Type → SStar ARM SoCs
找到使用设备树文件

修改设备树，在I2C0下添加的触摸屏节点

修改touchscreen目录下kconfig文件添加配置项

config TOUCHSCREEN_HYCONtristate "HYCON HY46XX Dual touch support capacitive touchscreens"depends on I2ChelpSay Y here if you have a touchscreen using HYCON HY46XX.If unsure, say N.To compile this driver as a module, choose M here: themodule will be called hy46xx_ts.

修改makefile文件

obj-$(CONFIG_TOUCHSCREEN_HYCON)  += hy46xx_ts.o

十三、虽然内核带CH340的驱动，但不是最新，可以从git或者官网下载最新

git clone https://github.com/juliagoda/CH341SER

替换掉Makefile文件

ARCH := arm
CROSS_COMPILE := arm-linux-gnueabihf-
KERNELDIR := /home/dm/ssd201/kernel
CURRENT_PATH := $(shell pwd)obj-m := ch34x.obuild: kernel_moduleskernel_modules:$(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNELDIR) M=$(CURRENT_PATH) modulesrm *.mod*
clean:$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) clean

生成驱动模块

make modules

十四、RTL8723 STA及AP驱动编译及调试

参考链接：https://www.cnblogs.com/rain-blog/p/rtl8723bs-driver-test.html
驱动模块放kernel/driver/net/wireless/RT8723目录下，修改父目录的Kconfig及Makefile

修改模块下Makefle添加一个当前平台编译选项，如下

ifeq ($(CONFIG_PLATFORM_SSD20X_ARM), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
SUBARCH := $(shell uname -m )
ARCH := $(SUBARCH)
CROSS_COMPILE := arm-linux-gnueabihf-
KSRC := /home/dm/ssd201/kernel
MODULE_NAME :=wlan
endif

编译成功生成wlan.ko文件

添加WIFI驱动库

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/lib:/config/wifi

//WIFI STA需要建立目录
mkdir -p /tmp/wifi/run
chmod 777 /tmp/wifi/run

//WIFI AP需建立目录
mkdir -p /var/run/hostapd
mkdir -p /var/wifi/misc
mkdir -p /var/lib/misc

十八、编译minicom2.8

ncurses-6.2.tar.gz 试过5.7-6.0版本编译出错，这个版本可以编译通过
minicom-2.8.tar.bz2

先编译ncurse6.2

./configure --host=arm-linux-gnueabihf --prefix=/home/dm/ssd201/debug-toos/install/ncurses-6.2 CXX="arm-linux-gnueabihf-g++" CC="arm-linux-gnueabihf-gcc" --with-shared

编译minicom2.8

./configure CC=arm-linux-gnueabihf-gcc --prefix=/home/dm/ssd201/debug-toos/install/minicom --host=arm --enable-cfg-dir="/tmp"  CPPFLAGS="-I/home/dm/ssd201/debug-toos/install/ncurses-6.2/include" LDFLAGS="-L/home/dm/ssd201/debug-toos/install/ncurses-6.2/lib"

CPPFLAGS 和 LDFLAGS是刚刚编译的ncurses的头文件和库目录
enable-cfg-dir是minicom运行时配置保存的指定路径

移植

export TERMINFO=/tmp
export TERM=vt100

将程序minicom和配置vt100拷贝到开发板/tmp/v 目录。（此目录取决于TERMINFO=/tmp）
最后运行： ./minicom

十九、编译libmodbus库

下载连接：https://github.com/stephane/libmodbus/releases/download/v3.1.10/libmodbus-3.1.10.tar.gz

./configure --host=arm-linux-gnueabihf --prefix=/home/dm/ssd201/LIB/install/libmodbus --enable-shared --enable-static

make & make install

二十、PM_LED0、PM_LED1作普通IO

修改UBOOT
修改boot/drivers/mstar/emac/infinity2m/mhal_emac.c文件中的MHal_EMAC_ClkGen函数注释如下内容:

#if 0
//enable LED //16'0x0e_28[5:4]=01
uRegVal = MHal_EMAC_ReadReg8(REG_BANK_PMSLEEP, 0x50);
uRegVal = (uRegVal&~0x30)|0x10;
MHal_EMAC_WritReg8(REG_BANK_PMSLEEP, 0x50, uRegVal);
#endif

EMAC内核驱动修改\kernel\drivers\sstar\emac\hal\infinity2m\mhal_emac.c，需要注释多个地方

设备树文件中关于PAD_PM_LED0与PAD_PM_LED1的需要注释

二十一、修改为RGB屏

1、修改project/board/i2m/SSC011A-S01A/config/fbdev.ini
2、RGB屏为888，修改设备树文件
3、修改屏参文件
查看riu_r 0x101e 0xd是否有切对TTL mode(value:0x100)/MIPImode(vacdlue:0x1000)
按照步骤操作：
跑点屏的demo，初始化disp和panel；
如果跑的是显示UI的demo，先下cmd：echo GUI_SHOW 0 off >/proc/mi_modules/fb/mi_fb0 关闭UI；
通过reg关闭csc：riu_w 1129 30 bit0写0，riu_w 1129 3c bit0写0；
通过reg打纯色pattern：
SSD20X寄存器如下：
4、测试纯色的pattern：
riu_w 1129 1b 8000
bule：riu_w 1129 1b 801f
green：riu_w 1129 1b 83e0
red： riu_w 1129 1b fc00

显示与实图，有点反色，调整VCOM电压
查看屏参
cat /proc/mi_modules/mi_panel/mi_panel0
修改project/board/i2m/SSC011A-S01A/config/fbdev.ini的分辨率

修改sstardisp.c分辨率

二十二、启动LOGO

修改UBOOT

CONFIG_CMD_BOOTLOGO
CONFIG_SSTAR_DISP
CONFIG_SSTAR_PNL
CONFIG_SSTAR_JPD

修改project/configs/current.configs

复制jpeg到project/board/ini/misc
添加UBOOT屏参文件project/image/makefiletools/src/rawgenerator/pnl
修改添加屏参文件到disp_data_main.c

屏参名称要与DISP_OUT_NAME相同

project/configs/current.configs

make image
启动到uboot修改bootcmd设置背光引脚打开

setenv bootcmd 'bootlogo 0 0 0 0 0; mw 1f001cc0 11; gpio out 12 0; nand read.e 0x22000000 KERNEL 0x26e6d4; gpio out 12 1; bootm 0x22000000;nand read.e 0x22000000 RECOVERY 0x26e6d4; bootm 0x22000000'

上电启动到UI有其它颜色显示，修改背景颜色为黑色
1、指定YUV黑色
#define MAKE_YUYV_VALUE(y,u,v) ((y) << 24) | ((u) << 16) | ((y) << 8) | (v)
#define YUYV_BLACK MAKE_YUYV_VALUE(0,128,128)
2、设定u32BgColor
if (pstDispPubAttr->eIntfType == E_MI_DISP_INTF_LCD)
{
log_debug(“sstar_disp_init 3”);
init_panel_ST7701S();
log_debug(“sstar_disp_init 4”);
pstDispPubAttr->u32BgColor = YUYV_BLACK; // 设置背景色
pstDispPubAttr->stSyncInfo.u16Vact = stPanelParam.u16Height;
pstDispPubAttr->stSyncInfo.u16Vbb = stPanelParam.u16VSyncBackPorch;
…
}

二十三、工程管理

使用Cmake作工程管理，添加第三方modbus与lvgl库

cmake_minimum_required(VERSION 3.0.0)
project(energy_storage VERSION 0.1.0 LANGUAGES C)include(CTest)
enable_testing()link_directories(/home/dm/ssd201/LIB/install/libmodbus/lib)
