本帖最后由 uclinux_2016 于 2017-7-30 16:35 编辑 有没有人用过3536的外部音频codec，修改编译选项后发现MCLK时钟频率不正确，看海思的手册说要设置I2S_CRG_CFG0_08 、I2S_CRG_CFG1_08 等一系列寄存器，但也没找到对应的API。 请高手指导一下，多谢了！

Hi3536的解码显示是4分屏的，项目需求在解码输出的窗口上显示一个OSD菜单， 有没有什么办法能够将OSD菜单以整个画面为基准进行显示，而不是显示在4个屏中的一个？ 不知道到底将ragion绑定到VDEC上/VPSS上/还是VO上才能实现这一功能。 请高手不吝赐教，多谢了！

编译3536的文件系统时，不知道demo下的rootfs_hi3536_2k_4bit_sample.yaffs2是怎么生成的。 哪位兄弟做过啊？能否能指导一下？ 多谢啦。

不知道大家有没有在3531上支持过2G内存，在项目调试时发现demo板上的1G内存在应用中内存不够运行不起来，想升级到2G内存，需要修改哪些地方呢？请高手指导下，多谢了。

本帖最后由 uclinux_2016 于 2017-7-30 16:36 编辑 3531能实现4路编码其中有些路是1080P有些是720P的么？看代码例程似乎不行啊。 有实现的兄弟帮忙指导下呗，多谢啦！
