dm365 怎么加入启动画面？

您好， 你是想用VPFE还是SD输出来做这个bootlogo？

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~

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？

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～

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

o，好的，多谢，我去看看。

哦 ，关于内核配置这个阻塞问题，不知道您有什么看法么？

我猜是内核已经做了一些显示部分的初始化，后面跑应用的时候又做了一遍，之间可能就有配置打架了
具体要看到底停在哪里了，因为你log中打印出来的东西停在哪里，代码里未必是在那个地方的

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。

Excuse me, 我找不到你说的VPFE工程，可否告诉我在哪里可以下载到？

查资料说很有可能是在VPSS初始化部分冲突了，内核默认VPSS是未初始化的，但配置LOGO后，其实是已经初始化过了，应该是这里冲突了，请问您知道内核中VPSS初始化这个该怎么修改下么。。

http://support.spectrumdigital.com/boards/evmdm368/revg/

您好。请问现在知道卡在哪里了吗。我也在启动内核时有时会卡住。我是在uboot加入logo...  

这个问题叫u-boot splash
给你一个参考的CCS工程，你可以把里面的代码加到u-boot里来实现开机界面 (多看看初始化VPBE的流程)
但是kernel起来之后，kernel里的framebuffer驱动起来之后会重新初始化VPBE， 这样会导致闪屏
比较好的做法是，u-boot里初始化VPBE，修改kernel里的framebuffer里的驱动，用ioremmap把u-boot里配置好的VPBE OSD/video窗口的地址映射到kernel空间来（注意地址冲突）

你好，请问你是怎么在Uboot下面添加的LOGO呢？我也想添加，不知道如何下手，能指点下吗？谢谢~~~
