Hi expert,
We try to do DPDK initialize with MC firmware 10.35 on dpmac3 port by the following command:
BSP is based on LSDK-20.04-update-290520
Linux Kernel is based on 4.19.90-rt35
DPDK version:19.11.6-rc1
DPDK Command:
export DPRC=dprc.2
export DPIO_COUNT=8
export DPMCP_COUNT=2
echo dpni.2 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/unbind
restool dpni destroy dpni.2
/usr/local/dpdk/dpaa2/dynamic_dpl.sh dpni dpni -b 00:00:00:00:07:00
/usr/local/dpdk/dpaa2/dynamic_dpl.sh dpni dpni -b 00:00:00:00:08:00
ls-addni --no-link --mac-addr=80:78:71:12:c3:96
restool dpdmux create --num-ifs=3 --method DPDMUX_METHOD_MAC --container=dprc.1
restool dprc connect dprc.1 --endpoint1=dpdmux.0.0 --endpoint2=dpmac.3
restool dprc connect dprc.1 --endpoint1=dpdmux.0.1 --endpoint2=dpni.2
restool dprc connect dprc.1 --endpoint1=dpni.3 --endpoint2=dpni.4
restool dprc connect dprc.1 --endpoint1=dpdmux.0.3 --endpoint2=dpni.6
restool dprc assign dprc.1 --object=dpdmux.0 --plugged=1
The command is running correctly without any error, but after running the command finished for a few minutes, system halts and shows the below error message, do you have any idea what cause this issue?
