请教spi1 st7789V怎么移植配置开机logo?

[hy123456]

硬件平台r528 ，tina 系统，u-boot-2018。用spi1 驱动一个st7789v的240*240的小屏。
kernel现在已经可以显示logo.但是uboot 阶段一直不显示？请教一下具体怎么配置？
还有请教uboot阶段系统运行开机logo的步骤？现在不知道怎么跟踪，不清楚问题出在那里？
修改了一下内容，还是没有显示：
1、tina-r528/lichee/brandy-2.0/u-boot-2018/include/configs$ vi sun20iw1p1.h
增加了头文件

  #define CONFIG_VIDEO_LOGO
 #define CONFIG_VIDEO_BMP_LOGO

2、tina-r528/device/config/chips/r528/configs/evb1$ vi uboot-board.dts
设备树修改

};

3、tina-r528/lichee/brandy-2.0/u-boot-2018/arch/arm/dts$ vi sun8iw20p1-soc-system.dts
增加SPi1 节点

4、tina-r528/lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd$ vi st7789v.c
修改驱动初始化

5、menuconfig 选择st7789v。

SPI 屏幕要取消勾选CONFIG_AW_PHY=y

[chinazhangdj]

@yuzukitsuru 大佬的Rosetta屏幕搞完没有，能出个教程嘛，R328+ST7789不知道怎么搞哎

[hy123456]

@yuzukitsuru 您好，我把vi lichee/brandy-2.0/u-boot-2018/configs/sun8iw20p1_defconfig 中的CONFIG_AW_PHY=y 注释掉了。试了一下，还是不行。我看
执行了show_bmp_on_fb

172856 bytes read in 9 ms (18.3 MiB/s)

[YuzukiTsuru]

@chinazhangdj 用fbtft驱动，配置io spi

[YuzukiTsuru]

@hy123456 我感觉他已经显示了只是没有开屏，这个有什么影响吗

[hy123456]

@yuzukitsuru 现在就是logo 显示的有些慢，大约上电4s左右到kernel 启动后才能显示出来。

@hy123456 6 为什么不尝试在uboot阶段就显示logo 再折腾一遍？

[hy123456]

@allwinnertech 是的就是想在uboot 中配置好，但是没有成功。
