小白新人求教uboot中怎么开启logo显示

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
