@jr_online 我用到的是方屏，也是和你一样，lvgl花屏，然后其他显示显示的是变成上下分屏，内容一致，要修改哪里？uboot的分辨率没同步设置？我这边是关了uboot的lcd驱动的

@whycan 之后在烧好tina镜像的卡上新建一个ext4分区，这一步怎么操作~~ 有没有已经搞好的rootfs，直接抄作业。哈哈

@yteraa 可以显示了。不过偏移有问题，还有错位了，迟些上图片，

@soso90 在 麻雀 d1s spi tft 开坑 中说：

@yteraa tf卡启动，没有修改到tf卡相关。只是添加了spi和改了你说的寄存器范围。刚才spi的dts错误的话，还能识别到。看日志好像现在是识别不到tf卡。

初步判断，有可能是io口引用冲突导致。这边有个疑问，d1s少了部分io。那么io计算方法是否还是和d1一致，也是按照每个pin有多少个做偏移，还是按照固定的io数去计算

@yteraa tf卡启动，没有修改到tf卡相关。只是添加了spi和改了你说的寄存器范围。刚才spi的dts错误的话，还能识别到。看日志好像现在是识别不到tf卡。

@yteraa 现在能识别，也正常挂载7789，就是系统根目录挂不了。真是奇怪~~没有改其他地方，就加了一个pin-name加了default这个，之前dts少了这个，才报申请io失败

修改了报错。现在能挂载上驱动。不过启动后，居然挂载不了根目录

@yteraa fbtft没有输出，spi这边还是报那个申请失败：sunxi_spi_probe()2476 - [spi1] Req mem region failed。这个spi失败的话，后面应该也不会去挂载fbtft吧

@yteraa 按照你说的，改了spi的范围，重新make和pack，还是报这个错误。是哪里还要配置？谢谢哈~ 看来这个东西，应该玩的人也少
