imx6，framebuffer只有fb0的问题。

[colinro]

请问下各路大神，我imx6ul开发板，系统启动后，为什么只有fb0呢，我想加fb1，又或者fb2，来做叠加，请问下在哪操作。在此感谢了。

[joanxie]

当板子起来以后，你到/sys/class/graphics,看看有什么？应该fb1已经有了的

[colinro]

感谢您的回复。 也是只有fb0，到底是什么问题呢？ 我是买的开发板，他们说是framebuffer是用的官方的驱动，应该没啥问题。 如果只有fb0，那不做不了叠加了么？ 麻烦指点。

[joanxie]

用的哪个版本的也说一下

[joanxie]

请描述下你的启动过程，你用的我们的DEMO IMAGE，然后用MFGTOOL烧录进去的吗？起来以后的LOG FILE也给我看一下，请描述得具体一点

[colinro]

感谢您的回复。望继续回复。谢谢。

下面是var/log下的messages文件里的内容，是通过MFGTOOL烧录进去的没错。内核版本 linux-3.14.38，麻烦帮忙看看什么情况？ 或者我还有什么方法可以做叠加么？  就是LCD显示一张图片，然后在图片上用freetype去画文字。 操作文字层的时候，不会改变下面图片层的内容。

请问用的是什么输出方式? 尝试下在kernel 命令行加入你的输出方式，

把 “Kernel command line: console=ttymxc0,115200 calibrate= cma=64M root=/dev/mmcblk1p2 rootwait rw“

加上你的输出方式然后启动看看，假如你用的是CLAA-WVGA dumb parallelLCD panel.那就加上“video=mxcfb0:dev=lcd,CLAAWVGA,if=RGB656”，然后启动后在"/sys/class/graphics"上看看
