我内核空间kmalloc一个10M的内存，失败！向看一下内核空间分配的大小

我ISP已经关闭，但是还是打印ISP的错误log，log截取如下，主要是两个

[ISP_WARN]open /mnt/isp0_ctx_saved.bin failed!!!
和
[ISP_ERR] func: isp_set_table1_map, line: 223,VIDIOC_VIN_ISP_TABLE_MAPPING error!

麻烦问一下是怎么回事？

@yteraa 那mac是怎么烧的？

有没有指导文档， 我自己的应用是放在package目录的，在这个目录中如何调用mpp接口？

咨询了板子厂家， 需要在softwinner/eyesee-mpp/middleware/v316/tina.mk中修改，把相应sample前面的#去掉即可，编译结果存放在各个sample自己的目录下

@yteraa

@yteraa 能发我一下吗？板子厂家给的资料 没这个

@yteraa 在 这个目录下的sample是怎么编译的 中说：

eyesee-mpp\middleware\

好像没有这个目录

@yteraa 编译生成的文件在哪里？我编译sample_vo，只在out/v536-Lindenis_SBC/compile_dir/target/eyesee-mpp-middleware/eyesee-mpp-middleware/media/目录找到一个libmpp_vo.so

这个路径下的各种sample是怎么编译的，softwinner/eyesee-mpp/middleware/v316/sample/

看不懂.mk文件 恳请帮助
