Hi Nvidia,
I am trying the multicast streaming fashion based on the nvscistream APIs (DRIVE OS 6.0), my producer has 2 consumers, and the consumers are running in the same terminal shell.

When the producer was coming to the below phase
============ Producer finalize requirements and map resources ===============

there was an error message log as follow:
NVMAP_IOC_GET_SCIIPCID failed [Operation not permitted]

and the producer can’t receive any packetStatus and elemStatus messages from the consumer.

Do you have any idea on this topic?

Many thanks,
Ray

Add more logs from the sample code nvscistream/event/

./nvscistream_event_sample -u 2 -m 3 -p -c 0 -q 0 m &
./nvscistream_event_sample -u 2 -c 1 -c 2 -q 2 m
NVMAP_IOC_GET_SCIIPCID failed [Operation not permitted]
NVMAP_IOC_GET_SCIIPCID failed [Operation not permitted]
IpcSrc received error event: 32

Consumer disconnected after receiving 0 payloads

Hi kayccc,

I can’t modify my email, so I removed the old account and registered a new one and then come to you.
I have been troubled by this problem for a long time, could you please give me any feedback or proposal?

Regards,
Ray

Dear @user110377,
Could you confirm the platform and DRIVE OS version?

Dear @user110377,
Could you check with your NVIDIA representative for support on this issue. This forum is intended to support only DRIVE AGX Xavier platform.

Thanks @SivaRamaKrishnaNV, and you can set this topic to CLOSED if you want.

Hi Siva,

Could you please just give me some proposal if the problem occurred on DRIVE AGX Xavier platform?
Such as how to fix this issue, how to investigate it.
I read the permission section in the the developer guide, the sample code is using the NVMEDIA api to set the scibufObj,hence, it’s impossible to have this permission complaint.

Regards,
Ray

Dear @user110377,
This sample seems to be not part of DRIVE AGX release. So I can not give any comment about it. As suggested please check with your NVIDIA representative.
