Other Parts Discussed in Thread: TEST2
Tool/software:
Hello Ti,
I'm currently testing with the release : 11.00.09.04
I found that there are two IRQs coming from queues from eth1 and eth2 for HSR packets. But the duplicated packets should be removed by the PRU firmware, I would expect only one IRQ.
Here is the procedure :
On u-boot :
=> setenv name_overlays 'ti/k3-am642-evm-icssg1-dualemac.dtbo' => printenv name_overlays => saveenv
Disable Network Manager :
systemctl disable dhcpcd.service systemctl disable NetworkManager.service systemctl disable systemd-resolved.service systemctl disable systemd-networkd.service sync reboot
Set Link speed to
ethtool -s eth1 speed 100 duplex full ethtool -s eth2 speed 100 duplex full
Enable HSR with the script proposed on ti doc + up eth1 and eth2

After pinging we see that the number of IRQs are increasing for eth1 and eth2.
I also have these undesired logs when enable HSR offload with the script :[ 31.757554] icssg-prueth icssg1-eth eth1: timeout waiting for command done [ 31.774708] icssg-prueth icssg1-eth eth2: timeout waiting for command done [ 31.781651] icssg-prueth icssg1-eth: Failed to restart the firmwares, aborting the process
Is it possible to reproduce this on your side ?
