hi,

During the kernel's boot-up, when enabled the follow function, kernel will stuck. kernel version is 4.14 and running with arm64 and kernel source code fetched as follow by Yocto from https://source.codeaurora.org/external/qoriq/qoriq-components/linux

{code}

CONFIG_FSL_SDK_DPAA_ETH=y
CONFIG_FSL_DPAA_OFFLINE_PORTS=y
CONFIG_FSL_DPAA_ADVANCED_DRIVERS=y
CONFIG_FSL_DPAA_ETH_USE_NDO_SELECT_QUEUE=y
CONFIG_FSL_DPAA_ETH_MAX_BUF_COUNT=128
CONFIG_FSL_DPAA_ETH_REFILL_THRESHOLD=80
CONFIG_FSL_DPAA_CS_THRESHOLD_1G=0x06000000
CONFIG_FSL_DPAA_CS_THRESHOLD_10G=0x10000000
CONFIG_FSL_DPAA_INGRESS_CS_THRESHOLD=0x10000000
CONFIG_FSL_DPAA_ETH_DEBUGFS=y
CONFIG_FSL_SDK_DPA=y
CONFIG_FSL_DPA_CAN_WAIT=y
CONFIG_FSL_DPA_CAN_WAIT_SYNC=y
CONFIG_FSL_DPA_PIRQ_FAST=y
CONFIG_FSL_DPA_PIRQ_SLOW=y
CONFIG_FSL_DPA_PORTAL_SHARE=y
CONFIG_FSL_USDPAA=y

{code}

And after reset the board, during u-boot, I dumped the __log_buf details, kernel run to follow:

If I disabled the DPAA function by setting "CONFIG_FSL_SDK_DPA=n" , kernel bootup successfully, kernel is running with arm64.

Hi,

I recently (friday) switched from USDPAA to DPAA SDK, my kernel config is the same as your, my kernel is booting.

Check your DTS file and use inspiration from fsl-ls1043a-rdb-sdk.dts, configuration is really different from fsl-ls1043a-rdb-usdpaa.dts. I had a segfault in kernel, changing the configuration resolved (for the moment) everything
