On successful probing of the DSA Felix switch, each available front panel switch port should have a network device interface attached with the swpX name format. The ip link show command uses the swpX@enoY name format to also indicate the associated master Ethernet interface for the DSA switch port, which corresponds to an internal ENETC interface, usually the eno2 (Port2) for the LS1028A SoC.

Follow these steps to update the  composite firmware image in QSPI NOR flash. cpld reset   boots the board from QSPI NOR flash0 and   cpld reset altbank   boots the board from QSPI NOR flash1. sf probe 0:1   means that the alternate bank will be written to. So, if the board boots from QSPI NOR flash0 and   sf probe 0:1   is entered at the U-Boot prompt, the commands that follow will program QSPI NOR flash1. Obtaining composite firmware image   LSDK includes pre-built firmware images for QSPI NOR flash. The LSDK composite firmware includes RCW+PBI, U-Boot/UEFI, PPA, boot loader environment variables, DPAA1 FMan ucode, QE/uQE firmware, Ethernet PHY firmware, device tree, and lsdk_linux_<arch>.itb images. Refer Flash layout for new boot flow with TF-A  for  t he complete flash memory layout of the images.   On a Linux host machine, download composite firmware image for QSPI boot from nxp.com.     $ wget  http://www.nxp.com/lgfiles/sdk/lsdk <LSDK version> /firmware_ <RDB_name>_uboot_qspiboot.img     For example:   $ wget http://www.nxp.com/lgfiles/sdk/lsdk1812/firmware_ls1046ardb_uboot_qspiboot.img   Flashing composite firmware   images   to   QSPI NOR flash Composite   firmware   image can be loaded to LS1046ARDB from a TFTP server or from a mass storage device (SD, USB, or SATA).

FlexSPI controller is new IP from Microcontroller group and it will replace QSPI in all future SoCs. FlexSPI is superset and superior to QSPI. Most of the feature set of FlexSPI and QSPI are same, but there are few difference related to IO signal width, command set, default LUT programming and Hyperflash support. FlexSPI has AHB and IP bus interface. AHB 64-bit interface and is mainly use for READ and WRITE flash operation whereas IP is 32-bit interface and it supports all flash operation – READ, WRITE, STATUS CHECK, GET PARAMS etc. FlexSPI programs various commands in LUT and these commands sequence are trigger when we do AHB/IP bus READ/WRITE operation. This documents introduces FlexSPI controller, FlexSPI serial NOR driver implementation and FlexSPI serial NAND driver implementation.  1.  FlexSPI Controller Introdunction 1.1 FlexSPI Connections 1.2 FlexSPI Command Interfaces 1.3 FlexSPI Look Up Table(LUT) 1.4 FlexSPI Command Set (Programmable Sequence Engine)   2.

NXP created eIQ machine learning software for QorIQ Layerscape applications processors, a set of ML tools which allows developing and deploying ML applications on the QorIQ Layerscape family of devices. OpenCV is an open-source computer vision library. It offers a unitary solution for both the neural network inference (DNN module) and the standard machine learning algorithms (ML module). It includes many computer vision functions, making it easier to build complex machine learning applications in a short amount of time and without being dependent on other libraries. This document describe applications YOLO object detection, Image segmentation, Image colorization, Image classification, Human pose estimation and Text detection developed based on OpenCV DNN framework.

The below steps describe how to modify the content of the existing rootfs. Steps are explained using LX2160ARDB board, however, the steps are applicable to all Layerscape devices and boards. Extract and modify contents of cpio.gz archive Generate .itb image Set up Ethernet connection between TFTP server and Layerscape board Boot the Linux kernel using new .itb image Step1: Extract and modify contents of cpio.gz archive Create a temporary directory for extracting the contents of the cpio.gz archive image. For example: mkdir temp_folder.   Extract the contents of the cpio.gz archive in the temporary folder. For example: gunzip -c rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz | sh -c 'cd temp_folder/&& cpio -i' The temporary folder lists the filesystem as follows:  bin boot dev etc home init lib media mnt proc run sbin sys tmp usr var Make changes to the filesystem in the temporary folder. For example: copy a 'HelloWorld' file in the filesystem using the following command: cp <path>/HelloWorld . Repack the filesystem into a new cpio.gz archive. For example: use the following command: sh -c 'cd temp_folder/ && find . | cpio -H newc -o' | gzip -9 > new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz   Step2: Generate .itb image Change the path for new rootfs (new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz) in linux_arm64_LS.its using gedit editor. For example: Change directory to flexbuild_lsdk<version>/configs/linux. gedit linux_arm64_LS.its Update path as follows:  data = /incbin/("../../packages/rfs/initrd/new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz"); Generate .itb image using the following command: For example: flex-builder -i mkitb -r yocto:tiny This generates lsdk2012_yocto_tiny_LS_arm64.itb image. Copy the .itb image to the TFTP server. Step 3 - Set up Ethernet connection between TFTP server and Layerscape board Set up Ethernet connection between the board (for example, LX2160ARDB) and host machine on which you have configured the TFTP server. Boot the board to U-Boot prompt. U-Boot prints a list of enabled Ethernet interfaces. For example, LX2160ARDB U-Boot prints following Ethernet interfaces. DPMAC2@xlaui4, DPMAC3@xgmii, DPMAC4@xgmii, DPMAC5@25g-aui, DPMAC6@25g-aui, DPMAC17@rgmii-id, DPMAC18@rgmii-id  Set server IP address to the IP address of the host machine on which you have configured the TFTP server . => setenv serverip <ipaddress1> Set ethact and ethprime as the ethernet interface connected to the TFTP server. See LX2160ARDB Ethernet Port Mapping for the mapping of Ethernet port names appearing on the chassis front panel with the port names in U-Boot and Linux. =>   setenv ethprime <name of interface connected to TFTP server> For example: => setenv ethprime DPMAC3@xgmii => setenv ethact <name of interface connected to TFTP server> For example: => setenv ethact DPMAC3@xgmii Set IP address of the board. You can set a static IP address or, if the board can connect to a dhcp server, you can use the dhcp command.  Static IP address assignment: => setenv ipaddr <ipaddress2> => setenv netmask <subnet mask> Dynamic IP address assignment: => dhcp Save the settings. => saveenv Check the connection between the board and the TFTP server. => ping $serverip Using DPMAC3@xgmii device host 192.168.2.1 is alive Step4: Boot the Linux kernel using new .itb image Load the .itb image from TFTP server to DDR memory of the board. => tftp 0xa0000000 <itb_file_name> For example:   => tftp 0xa0000000 lsdk2012_yocto_tiny_LS_arm64.itb Boot the kernel with .itb image as follows: => bootm 0xa0000000#<board_name> For example:   => bootm 0xa0000000#lx2160ardb Let the board boots to Tiny Linux. List the filesystem. NXP LSDK tiny 2012 (based on Yocto) TinyLinux login: root root@TinyLinux:~# ls root@TinyLinux:~# cd / root@TinyLinux:/# ls HelloWorld boot etc init media new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz root sbin tmp var bin dev home lib mnt proc run sys usr root@TinyLinux:/# You will observe the HelloWorld file available in the filesystem.

This topic explains steps to compile and execute Hello World program (in C) on a Layerscape board. Similarly, you can execute other custom applications on your board. Create a Hello World program in C.  Copy this file (.c) on a Ubuntu machine (using WinSCP). Run the following command to convert the .c file into a binary file. $ aarch64-linux-gnu-gcc <.c file> -o <binary file> For example: $ aarch64-linux-gnu-gcc Hello_World.c -o Hello_World Note: You can use this command in the same directory in which .c file is present or provide path of this file. Connect to the board console on which you want to execute the custom application via terminal and boot the board with LITB. Note: It is suggested to boot the board with Tiny Linux for executing custom application.  => tftp 0xa0000000 lsdk2004_yocto_tiny_LS_arm64.itb Using e1000#0 device TFTP from server 192.168.3.1; our IP address is 192.168.3.142 Filename 'lsdk2004_yocto_tiny_LS_arm64.itb'.
