RT内核没研究过，不过可以先试试普通内核能不能启动手动打入rt补丁看看

回复: 请教如何排查 linux kernel 启动卡主的问题发布在 Linux
@xsyr1024 在 请教如何排查 linux kernel 启动卡主的问题 中说：
[ 0.969253] 000: printk: console [ttyS0] enabled
[ 0.973945] 000: printk: bootconsole [earlycon0] disabled看着是earlycon0作为串口输出驱动正常，但是切换到ttyS0作为串口输出的时候ttyS0没有输出，先检查uart部分
另外这个是LinuxRT内核吗

Sensor输出图像格式
sensor输出图像格式定义在sensor_format_struct结构体中，vin v4l2驱动框架通过获取sensor_format_struct结构体成员信息来获取当前sensor输出图像格式，sensor_formats结构体中需要填写的成员是.desc和.mbus_code。
.desc是描述sensor输出的图像格式，本例中gc2053是RGB Raw sensor，故.desc成员填写为"Raw RGB Bayer"。.mbus_code为sensor图像数据输出顺序，sensor RAW图像是以Bayer格式传输的（每个像素只表示RGB其中一个分量），常见的Bayer格式为：RGGB、BGGR、GRBG、GBRG，这个可以询问一下sensor原厂或者翻阅sensor datasheet进行查找。.mbus_code若填错, 会导致色彩偏紫红和出现网格状纹理。 本例中
gc2053图像输出格式为RGGB，且当前的配置是10bit mipi接口，故.mbus_code填写为
MEDIA_BUS_FMT_SRGGB10_1X10，若当前调试的sensor配置是8bit输出，
则.mbus_code填写为MEDIA_BUS_FMT_SRGGB8_1X8，按照这种规则进行填写。static struct sensor_format_struct sensor_formats[] = { { .desc = "Raw RGB Bayer", /* 填写 Sensor 初始化时默认的 Bayer 格式，目的是告知主控端ISP当前图像的 Bayer 格式，ISP需要以同样的格式来接收和处理图像数据 */ .mbus_code = MEDIA_BUS_FMT_SRGGB10_1X10, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 1 }, }; 如果
sensor输出图像格式是YUV的话，则需要根据sensor图像数据输出顺序选择YUYV/VYUY/UYVY/YVYU其中一种，如下：static struct sensor_format_struct sensor_formats[] = { { .desc = "YUYV 4:2:2", .mbus_code = MEDIA_BUS_FMT_YUYV8_2X8, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 2, }, }; 同时，
sensor_get_fmt_mbus_core函数也要将当前sensor的图像输出格式赋值给函数参数*code，有些sensor在翻转后RGB顺序不会自动进行调整，需要主控端ISP需要按照当前sensor翻转后的图像格式更新RGB顺序，避免翻转后出现图像色彩异常的问题，如下，gc2053支持翻转后sensor内部自动调整RGB顺序，所以函数参数*code仍赋值为MEDIA_BUS_FMT_SRGGB10_1X10。static int sensor_get_fmt_mbus_core(struct v4l2_subdev *sd, int *code) { *code = MEDIA_BUS_FMT_SRGGB10_1X10; // gc2053 support change the rgb format by itself } static long sensor_ioctl(struct v4l2_subdev *sd, unsigned int cmd, void *arg) { int ret = 0; struct sensor_info *info = to_state(sd); switch (cmd) { case VIDIOC_VIN_GET_SENSOR_CODE: /* vin v4l2框架层在sensor翻转接口被调用后， 通过VIDIOC_VIN_GET_SENSOR_CODE获取当前sensor的RGB顺序 */ sensor_get_fmt_mbus_core(sd, (int *)arg); break; default: return -EINVAL; } return ret; } -

回复: V853使用MIPI CSI接口是否只支持RAW格式像素？发布在 V Series
重新确认了一下，MIPI 接受的数据格式与MIPI无关，也就是MIPI也可以接收YUV这类数据。
是否是因为后端配置的问题。参考T507的TC358743驱动配置的是
MEDIA_BUS_FMT_UYVY8_2X8 -

回复: V853 DDR原理图问题发布在 V Series
AW平台的DRAM控制器支持地址线REMAP，可以通过REMAP简化外部不同种类的DRAM的连接。
这个REAMP是固定在芯片里的不能自己修改，在电路原理图可以看到REMAP的引脚。
如图，如果需要挂DDR3内存，需要接DDR3的REAMP，如果需要接DDR2，可以接默认的REMAP
举个其他平台的例子：
这里接的是 LPDDR4，使用LPDDR4的REMAP
这里接的是DDR4，使用DDR4的REMAP

回复: R128的屏幕颜色显示异常时怎么回事？发布在 A Series
jlt35031c是比较少见的小端屏，但是大部分的SPI屏都是大端屏，所以用jlt35031c时，需要修改sys_config.fex里面的配置项lcd_rgb_order为9.
unsigned char color[4] = {0xff,0x0,0xff,0x0};
这个数组决定颜色，颜色顺序是R（红） G（绿） B（蓝） A（亮度）。
所以红色 + 蓝色，应该是紫色
但是这里由于使用的是SPI接口驱动这个屏幕，并不支持lcd_rgb_order的参数配置。所以在屏幕初始化的时候通过写寄存器配置为对应的接口以支持LVGL的正确显示输出。但是测试命令可能会出现反色的情况。
