Hi
剛試了一下, 把fbmem=28M
不會崩潰, 但沒畫面,

fbmem=28M可以，不要0。能正常显示说明就OK的了。

欢迎楼主有问题继续在本论坛中交流讨论哈~~

spartanc

您好

不加0M HDMI會無輸出. 需要fbmem=0M,28M 這樣才有畫面輸出.

等等再試試
謝謝囉

我这边试过：
bootargs=console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1ff video=mxcfb2ff fbmem=28M androidboot.console=ttymxc0 vmalloc=400M androidboot.hardware=freescale
是显示OK的。建议你再试一下哈。

建议你再试试看哈，有问题再给我回复~~

真怪, 還是不行.

楼主，请问你板子上跑的Images是你自己编译的还是官网的Demo？

自己編譯的image.

楼主你好，请问你这里是不是需要设置：fbmem=0M,28M ，然后就可以正常工作了呢？

FSL_TICS_Rita

是的, 只要fbmem=0M, 28M就可以正常工作了
