TDA4VM: After updating tisdk-default-image ,How to Generate R5/C6/C7 firmware

Part Number: TDA4VM

HI All,

    I meet a problem when running vision_apps_init.sh, as shown in the figure below.

    

    After running vision_apps_init.sh, I run my app, and the following error occurred.

The premise of all these errors is that I updated the rootfs(PS:tisdk-default-image is regenerated from yocto and  firmware such as r5, c66 are generated based on the new image).

Finally, I carefully looked at the log at startup, and found that there was no print of the rpmsg_dev channel created as normal, as shown in the figure below.

Can anybody help me to figure out this problem?,
