DPDK initialize issue based on LX2160ARDB_Rev2

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?

Error log:

BR,

Thanks

I verified LSDK-20.04-update-290520 pre-built image with MC firmware 10.38, didn't reproduce your problem. Please refer to my attached log.

Please try the attached MC firmware 10.38 whether your problem persists.

If this problem persists, please try to use the pre-built image of LSDK-20.04-update-290520 to do verification.
