TDA4VM: iperf3 test Gigabit Ethernet caused graphs running on mcu2_0 stop during process

Hi all,

       The three graphs (GPIO level detection, ADC sampling, PPS periodic interrupt monitoring) which run on mcu2_0 continue to run for 3 days without problems, but with iperf3 testing (run on A72) Gigabit Ethernet (through cpsw9g switch RGMII port5) After that, it will cause the three graphs to hang in succession, and the hang in the process function does not return to A72 normally.The code is shown as fellow.Will iperf3 affect the resources of mcu2_0? At present, we see that iperf3 occupies about 20% of A72 when running with 900Mbps TCP communication.

Regards,

Jason
