int myzr_bmp_logo_size = sizeof(myzr_bmp_logo);<br>



=== 替换C文件(replace C file) ===
将myzr.c 改名为 myzr_bmp_logo.c，并替换掉 u-boot 源码中的 board/myzr/common/myzr_bmp_logo.c<br>
<span style="background:#CCCCCC">change myzr.c to be named as myzr_bmp_logo.c，then replace board/myzr/common/myzr_bmp_logo.c in u-boot source code with it</span><br>
