TI中文支持网各位前辈好，我想在代码启动的时候加入一个图片作为启动界面，就像我们的台式机bios里面的启动画面一样，请各位不吝赐教～小弟先谢过了～～
Eason Wang：
您好， 你是想用VPFE还是SD输出来做这个bootlogo？
Qianshun LIU：
回复 Eason Wang:
感谢回复~昨天晚上我已经基本实现了，就是配置一下内核选项，/kernel/device drivers/graphics support/logo configuration 。根据help说明，需要FB或者SGI_NEWPORT_CONSOLE的支持，我不知道SGI_NEWPORT_CONSOLE是什么，于是我配置了Frame buffer support。 重新编译烧写，果然可以看见开机logo，但是有一个问题，系统总是会卡住，不能继续运行，在没有配置logo之前，绝对没有这个现象，不知道我哪里少选了，还是哪里冲突了？ 多谢指教~
Eason Wang：
回复 Qianshun LIU:
是停在kernel还是停在哪里？按你说的，也不是每次都卡住，还是说每次卡住的地方不一样? 可能需要你提供一下当时的log
顺便想问一下，因为你这个是kernel下的logo，从系统加电到出现logo大致需要多久？
Qianshun LIU：
回复 Eason Wang:
恩，确实不是每次都停，但阻塞的时候居多，程序阻塞在了AVSERVER UI: Initializing 的上一行，也就说没有能进入到avserver ui initial里面。请看下面的log：
从上电到出现logo大约6-7s的样子。我本来是想在uboot里面实现logo，但由于之前没做过，加上看到kernel里面有logo可以配置，就图省事了。

请问如何在uboot里面实现呢？如果可以在uboot里面实现是最好的了～
Eason Wang：
回复 Qianshun LIU:
uboot里面是可以做的，不过需要你自己去配置寄存器了。可以参考开发板自带的VPFE工程去做这个
Qianshun LIU：
回复 Eason Wang:
o，好的，多谢，我去看看。
Qianshun LIU：
回复 Eason Wang:
哦 ，关于内核配置这个阻塞问题，不知道您有什么看法么？
Qianshun LIU：
回复 Eason Wang:
哦，好的，虽然我还不知道怎么解决他，不过非常感谢您的耐心回答～～等我弄好了贴出来办法，希望可以帮助其他人。
