        vim /boot/firmware/config.txt 一样修改dtb文件名试下。你的机器是什么时间收到的,早期的loader不识别extlinux.conf

        另外查看下 ls -l /sys/class/drm/

              @tonyone0902 如果有环境,建议更新到0315 版本loader。

                我也试了微雪的这个5寸屏
                不支持双指 打开一张本地的图片 不能用双指进行缩放 只能用鼠标滚轮缩放
                但是这个屏接树莓派4b是能用双指缩放的
                这个需要改哪里吗?

                      可以试下修改内核源码

                      drivers/input/touchscreen/tinker_ft5406.h
                      @@ -13,7 +13,7 @@
                       #define FT_REG_FW_SUB_MIN_VER  0xB3
                       
                       #define VALID_TD_STATUS_VAL            10
                      -#define MAX_TOUCH_POINTS               1
                      +#define MAX_TOUCH_POINTS               5
                      

                      重新编译内核,替换Image
