用的2020.07版本的uboot，是不是要再buildroot中配置一下，找来找去没找到，请大神指教
大概原因好像是 uboot tool/bmp-logo.c没有参与编译，没有bmp-logo.o生成，开机时提示 Unknown command 'bmp' - try 'help'

check CONFIG_CMD_BMP=y
BMP命令已添加，但是又报了个错 Error: compression type 3 not supported 会是啥情况

LZ,解决没有,一模一样的问题
解决了，一两句也说不清楚，慢慢摸索出来的，跟应用场景有关
1、bmp命令是在uboot的 menuconfig里可以配置的；
2、git上的r3 down下来的源码中uboot的env在调用bmp_display的时候变量名有点问题 （TF卡启动时是 mmcx，这里少了个x，x是0还是1，忘记了）；
3、TF启动时的加载bmp到内存的地址似乎不太合适，是要换到后面点；
4、原始的 splash.bmp的格式，并不能用bmp_display打开显示；
5、uboot中要显示还需要加个宏
在 uboot/include/configs/suniv.h 中加入两个宏定义：
#define CONFIG_VIDEO_LOGO
#define CONFIG_VIDEO_BMP_LOGO
下面的env我只是加载了logo.dat文件的内容，并没有显示，因为我准备在kernel中再显示，并且logo.dat的格式是我自定义，但是关于bmp的问题这里已经修改了
