PROCESSOR-SDK-AM64X: HSR setup on AM64x-EVM (TMDS64EVM)

Part Number: PROCESSOR-SDK-AM64X

Hi,

I am using latest TI SDK release www.ti.com/.../PROCESSOR-SDK-AM64X

PROCESSOR-SDK-LINUX-RT-AM64X — Processor SDK RT-Linux for AM64x  Version: 09.00.00.03

For HSR I am following next doc to setup HSR with Linux HSR Offload Support

https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/09_00_00_03/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/HSR_PRP.html

Also, I setup DTB overlay to configure eth1 and eth2 as PRU 

By executing script from this link in chapter "Linux HSR Offload Support"

sh ./<script_filename.sh> hsr eth1 eth2 192.168.2.20

I see next messages:

remoteproc remoteproc13: unsupported resource 5

remoteproc remoteproc15: unsupported resource 5

QUESTION: what is this message and is it correct to have it? 

Also, on same image I did next tests:

  • disable all systemd services to start network interfaces on boot
    • systemctl stop dhcpcd.service
    • systemctl disable dhcpcd.service
    • systemctl stop NetworkManager.service
    • systemctl stop systemd-resolved.service
    • systemctl disable NetworkManager.service
    • systemctl disable systemd-resolved.service
    • systemctl stop systemd-networkd
    • systemctl disable systemd-networkd
    • sync
  • reboot the board and check if there is no any network up

  • execute hsr script  
    sh ./<script_filename.sh> hsr eth1 eth2 192.168.2.20
  • I see next error

[   55.732459] remoteproc remoteproc11: unsupported resource 5

What are these errors and is there an impact on system?
