    • 全志哪些芯片是DRM驱动？哪些是fb+de驱动？

      全志哪些芯片支持DRM驱动？哪些是fb+de驱动？现在被T113S3上的显示图层问题搞崩溃了，disp手册就说了一下总体框架和各种接口的含义，具体通道数量，图层数量不一定所有型号IC都一致，/sys/class/disp/disp/attr能获取的信息不多，ion显存这块没说怎么分配，直接跑参考的demo项目只要涉及显示的除了播放视频demo显示正常，其他的全部发生段错误，libuapi也看了，videoOutPort.h也看了，libuapi配置的时候还不能选用cma分配内存，不然自带的lvgl demo都起不来,只能用ION，displayV1和V2又是什么区别？懵逼了，要是支持drm框架就舒服了？后面新出的V851 V853是DRM框架吗？drm只要modetest一看整个显示逻辑就清晰多了。

    • T113S3 DE显示图层怎么使用？

      看DISP的PDF有一些描述，但是不是很清楚，比如要显示多个图层时，每个图层的内存怎么申请和分配？只显示一个图层的时候，mmap申请内存就可以推到fb0显示，多图层不知道怎么管理，像drm框架有crtc,crtc下面有多个plane,每个plane的显存都是分开的，很直观，这个私有的disp框架有点搞不懂，播放视频demo的显示部分是封装的吧？看不到实现

      i2c读写部分都在这儿了，写部分没问题了，读部分不知道有没有问题，写正常就点亮了我就没排查读了，我读ncs8801s时相关寄存器的值和预期不一样，但是屏亮了，我暂时不管了，后面有时间再看是值确实不对还是读的时序不对导致读出的值不对

    • Tian的设备树大概的加载逻辑是什么？

      回复: 请问sys_config.fex与board.dts是什么关系

      看打包流程设备树最终应该是打包成了sunxi.fex,然后最后是合并到sys_partition.fex描述的boot分区吗？看uboot感觉又是放在FAT分区，有点理不清逻辑了，和uboot defconfig的这几个参数有关吗？

      CONFIG_SUNXI_NECESSARY_REPLACE_FDT=y
CONFIG_RESERVE_FDT_SIZE=0x20000
CONFIG_SYS_TEXT_BASE=0x43000000
CONFIG_SUNXI_FDT_ADDR=0x41800000

      我想打包多份设备树在这个设备树分区里面，根据其他条件选择加载哪一份设备树

      @lztmfx 在 Tina linux用屏幕转换芯片时I2C初始化问题 中说：

      用上面的方法二报错是其他原因报的错，排查后不报错了，不过I2C还是通讯不上

      GPIO模拟I2C调通了，贴下主要部分：

      #define I2C_SCL  204 //PG12
#define I2C_SDA  205 //PG13

#define I2C_SCL_HIGH() (gpio_set_value(I2C_SCL, 1))
#define I2C_SCL_LOW()  (gpio_set_value(I2C_SCL, 0))
#define I2C_SDA_HIGH() gpio_direction_input(I2C_SDA) // 释放SDA（外部上拉拉高）
#define I2C_SDA_LOW()  gpio_direction_output(I2C_SDA, 0)
#define I2C_SDA_READ() gpio_get_value(I2C_SDA)

static void i2c_start(void)
{
    I2C_SDA_HIGH();
    I2C_SCL_HIGH();
	udelay(5);
    I2C_SDA_LOW();
	udelay(5);
    I2C_SCL_LOW();
}

static void i2c_stop(void)
{
    I2C_SDA_LOW();
    I2C_SCL_HIGH();
	udelay(5);
    I2C_SDA_HIGH();
	udelay(5);
}

      注意使用完GPIO后要释放掉，否则后面用到这两个IO的驱动就要报错了，因为这两个IO是真正的I2C PIN，后面I2C驱动用得到，我这个案例就是驱动需要I2C初始化，但是LCD驱动在I2C驱动之前加载，在LCD驱动里面用不了硬件I2C的功能，查了资料，如果从调整驱动加载顺序的思路入手，能查到的方法要么不实际要么没有任何效果。不能让I2C在LCD前加载那就只能GPIO模拟I2C了，参考ST7789V GPIO模拟SPI看着不可行，实际没有测试，因为模拟SPI的GPIO可以不切换方向，而I2C SDA在ACK时需要切换输出为输入，在设备树定义gpio_x的方法不知道怎么在驱动切换GPIO方向，最终使用gpio_request()的方法申请GPIO来做

    • Tina linux用屏幕转换芯片时I2C初始化问题

      T113S3使用NCS8801 LVDS转EDP芯片，需要LCD驱动里面通过I2C初始化NCS8801，但是实际测试发现，tina linux的i2c晚于disp驱动加载，这样disp驱动里面获取不到有效的i2c适配器。有什么方法让i2c在disp前加载？另外看别的帖子说不建议在disp里面用硬件i2c初始化，推荐用GPIO模拟，看了SDK里面ST7789V也是用GPIO模拟SPI，但是SPI write的时候，引脚的输入输出是固定的，不用切换引脚状态，但是I2C的SDA引脚在发送完数据后需要切换为input模式来接收ACK信号的，这样如果用lcd设备树里面的这种方式是不行的吧？这个还可以在disp驱动里面通过代码切换lcd_gpio_X的参数吗？如输入改为输出。

      lcd_gpio_0 = <&pio PG 12 1 0 3 0>;
lcd_gpio_1 = <&pio PG 13 1 0 3 0>;

      如果直接在disp驱动使用下面这种方式：

      #define I2C_SCL  204
#define I2C_SDA  205
#define I2C_SCL_LOW()  gpio_set_value(I2C_SCL, 0)
#define I2C_SDA_HIGH() gpio_direction_output(I2C_SDA, 1)

      开机会有一堆报错

      最后就是官方LCD调试PDF文档里面提到过SPI，I2C初始化的方式，是通过读取设备树信息probe设备的方式，那理论上这种也是需要i2c在disp之前加载吧，而且他T113S3的设备树貌似无法匹配手册上的方法。

      如果固件下载到NAND，报错结束后内核就报错卡死了，同一个固件用TF卡启动就先报NAND的ECC错，最后能正常启动。这种情况是不是大概率是NAND坏了？

    • 回复: D1S TF卡启动固件修改文件系统无法启动

      论坛逛了一圈，成功进入系统。
      主要修改点：
      1.uboot里面menuconfig使能etx4
      2.kernel里面menuconfig使能ext4，取消squashfs
      3.SDK/device/config/chips/d1s/configs/default/env.cfg里面将rootfstype=squashfs改为rootfstype=ext4
      4.如果make成功，pack失败就修改SDK/device/config/chips/d1s/configs/nezha_sd/sys_partition.fex的相应分区大小，一般都是rootfs分区大小不够，需要多大才够可以看pack的报错有显示

    • 回复: Tina Linux 存储介质切换：eMMC，SPI NAND，SPI NOR，SD Card，SD NAND

      D1S/F133默认nand,sd,都是ubi只读文件系统，想要TF卡为EXT4文件系统，buildroot取消squashfs,选ext4后uboot就报错找不到分区了，uboot和kernel都选好了ext4，还是不行，还要修改什么地方？

    • D1S TF卡启动固件修改文件系统无法启动

      D1S默认启动TF卡固件为squashfs文件系统,可以正常启动。然后在tina根目录用make menuconfig把squashfs取消了，选择了ext4,kernel配置也选了对ext4文件系统的支持，编译后无法引导，看样子是挂在uboot了，报错如下：
