TDA4VH-Q1: Matching device not found error while creating endpoints

Part Number: TDA4VH-Q1

Tool/software:

Hi,

I am using sdk v11.

I am trying to create endpoints for all the remote cores on A72 in my app but getting below error. I am following same steps there are in app_utils->ipc util.

_rpmsg_char_find_ctrldev: could not find the matching rpmsg_ctrl device for virtio6.rpmsg_chrdev.-1.100

Logs below:

Looks like it is able to create it for R5F cores but failing for C7x cores. What could be the reason ? 

Thanks and regards,

Lalit
