Responses:
Hi Shuai, You can use the null src of the core where you are running the null src link. If you are reading from the file then it has to be in hlos only as file system is controlled by hlos, If you are running bios then it can be either A15 or M4 , depending you need to change the cfg file. vision_sdk\apps\configs\<sellected cfg> Regards Chetan.M

Hi Chetan.M i want to run null src link on M4 I am use LINUX system by hlos . BESTWISHES shuai

shuai when you run Linux on A15, both SD card and network will be controlled from A15 linux, so the NullSRc on M4 can not access these devices. regards, Shiju
