Hi,
I was trying to establish communication between R5F-0 and R5F-1 using message queues. However, it appears that R5F-0 is unable to successfully open the message queue created by R5F-1. I have attached the trace logs from both processors below:

Here R5F-1:MsgQ:01 is created by R5F-1 and R5F-0:MsgQ:01 is created by R5F-0.
The R5F-0 code simply does not find R5F-1:MsgQ:01.
I was wondering if there is any additional configurations that needs to be done to allow Message queue communication between the two R5F cores.
Message queue between R5F-0<->A53 and R5F-1<->A53 work perfectly fine.
Thanks in advance
