Tool/software:
We are currently encountering the following issue: after entering the Linux system, there is a high probability that inter-core communication with the M4F fails. At present, we load the M4F during the U-Boot phase and attach the M4F during the Linux phase. On the M4F side, it appears that an announce message is not received once, which may be causing subsequent communication failures.
Is there any way to query the announce information sent from M4F in Linux?
What might cause the above situation to occur?
Do you have any debugging suggestions?
