修改了bootlogo.bmp，将sys_partition.fex里的boot-resource改为880，用PhoenixCard烧录，报错。

为啥Kernel阶段的LCD显示只能显示一半，uboot.dts和board.dts在lcd位置配置是一致的

按照D1-H的音频开发指南配置内置音频接口，出现如下错误，是什么原因啊
root@TinaLinux:/home# aplay -Dhw:audiocodec text2audio.wav
Playing WAVE 'text2audio.wav' : [SNDCODEC][sunxi_card_hw_params][620]:stream_flag: 0
Signed 16 bit Little Endian, Rate 16000 Hz, Mono
aplay: pcm_write:1980: write error: Input/output error

@whycan 这些我真的改了，现在搞不明白，目前mmc2和uart0不冲突，为什么mmc2 not
found ,另外内核启动介质是在sys_config.fex里面配的吗？

@whycan 您的意思是我的DTS还是有问题，导致MMC2 not found，对吗

@whycan
感谢，已解决，但是碰到到MMC2 not found的问题，我用的是芒果派，TF是sdc0
