RTE_KNI load failed in LS1046ARDB

sheikfaaruk — Wed, 14 Sep 2022 05:43:29 GMT

I am working with LS1046ARDB Evaluation Board to develop a network based application. I have started my project with Flex-builder(flexbuild_lsdk2108), Flex-installer(version: 1.13.2108) and Codewarrior IDE.

I have download the images from https://lsdk.github.io/components.html

boot_LS -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/boot_LS_arm64_lts_5.10.tgz

firmware image -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_ls1046ardb_sdboot.img

Rootfs -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/rootfs_lsdk2108_ubuntu_main_arm64.tgz

I have depolyed the image's in SD card through flex-installer:

$ flex-installer -i pf -d /dev/sdx (partition and format the target storage device)

$ sudo flex-installer -b boot_LS_arm64_lts_5.10.tgz -r rootfs_lsdk2108_ubuntu_main_arm64.tgz -f firmware_ls1046ardb_sdboot.img -d /dev/sdx

I have booted the board using SD card

u-boot :

=> setenv ethprime FM1@DTSEC6
=> setenv ethact FM1@DTSEC6
=> saveenv
=> boot

linux user-space :

user@localhost:~$ sudo insmod /usr/local/dpdk/rte_kni.ko kthread_mode=multiple
[sudo] password for user:
user@localhost:~$ sudo rmmod rte_kni
user@localhost:~$ ls /dev/kni
/dev/kni
user@localhost:~$ dmesg | grep kni
[ 45.396511] rte_kni: loading out-of-tree module taints kernel.
user@localhost:~$

user@localhost:~$ uname -av
Linux localhost 5.10.35 #1 SMP PREEMPT Fri Aug 27 22:03:58 CST 2021 aarch64 aarch64 aarch64 GNU/Linux

Now KNI loaded successfully with default build taken from internet

Custom Linux build from Flex-builder:

I have followed the steps in this document https://www.nxp.com/docs/en/user-guide/LSDKUG_Rev21.08.pdf -> 9.2.3.1 Build DPDK using Flexbuild

$ flex-builder -c linux:custom -a arm64

1. [ Deivce Driver -> Network device support -> IEEE 802.1AE MAC-level encryption (MACsec) (ENABLED) ]
2. [ Cryptographic API -> Hardware crypto devices -> Freescale CAAM-multicore platform driver backend (ENABLED) ]
3. [ Cryptographic API -> Hardware crypto devices -> Freescale CAAM job ring driver backend -> Test caam rng (ENABLED) ]
4. [ Deivce Driver -> Real Time Clock -> NXP PCF2127 (ENABLED) ]

$ flex-builder -c linux -a arm64

$ flex-builder -c cryptodev_linux -a arm64

$ flex-builder -c openssl -a arm64

$ flex-builder -i mkrfs -r ubuntu:main

$ flex-builder -i mkboot

$ flex-builder -c apps -a arm64

$ flex-builder -i merge-component -a arm64

$ flex-builder -i packrfs

$ flex-builder -i mkfw -m ls1046ardb

$ cd build/images

$ flex-installer -i pf -d /dev/sdx (partition and format the target storage device)

$ sudo flex-installer -b boot_LS_arm64_lts_5.10_202209121352.tgz -r rootfs_lsdk2108_ubuntu_main_arm64_202209121422.tgz -f firmware_ls1046ardb_sdboot.img -d /dev/sdx

I have booted the board using SD card

u-boot :

=> setenv ethprime FM1@DTSEC6
=> setenv ethact FM1@DTSEC6
=> saveenv
=> boot

linux user-space :

user@localhost:~$ sudo insmod /usr/local/dpdk/rte_kni.ko kthread_mode=multiple

After kernel configuration rte_kni was not loaded and shows "Invalid parameters"
