On the LS1046ARDB, there are 2 1G SGMII with PHY, but sometimes customer want to get PHY-less connection to evaluate the performance, so they may have to change the non-fixed link properties into fixed-link by reconfiguration the SW configuration. In this document, it will give details of configuring the LS1046ARDB to support the fixed-link requirement with LSDK2108 focus on the DTS and Linux kernel. The ethernet MAC in this document is FM1 mEMAC6: 1AE_A000h. Because there is no PHY-less connection on board. We only provide the status when the MAC has been configured.

When customer only has SD/eMMC on the customer board, when they don’t have CWTAP in hand, how do they boot the customer board(bare board) after the board come back from the factory for the first time. This document describes the steps how to use the CMSIS-DAP in this situation as a reference for user.

CMSIS-DAP is a useful tool and exists in some NXP reference boards, but how to use it. This document describes the steps how to use the CMSIS-DAP in the LS1034ARDB as a reference for user.

On the LX2160ARDB, there are 2 25G SFP interfaces, but no 10G SFP interface. When customer want to test the 10G SFPs to evaluate the performance, they have to change the 25G SFP interfaces into 10G by reconfiguration the SW configuration. In this document, it will give details of configuring the LX2160ARDB to support the customer’s 10G SFP interfaces requirement with LSDK2108. At the end, an image will be generated to deployed into the SD card. Because SD card is a convenient way boot up LX2160ARDB, if one wrong move could brick the system, the customer could unplug the SD card to repeat the steps below.

ENETC is a PCI Integrated End Point(IEP). IEP implements peripheral devices in an SoC such that software sees them as PCIe device. ENETC is an evolution of BDR(Buffer Descriptor Ring) based networking IPs. Key goal of the DPDK is to provide a simple, complete framework for fast packet processing in data plane applications. Using the APIs provided as part of the framework, applications can leverage the capabilities of underlying network infrastructure.DPDK been prominent software in user space for networking applications pushes for eNetc driver to be written in user space.

Introduction.   CodeWarrior TAP combined with a host debugger provide control and visibility into your target embedded system through a debugging process. Main tasks to test a Reference Design Board with are: Flash an storage device for userspace debugging and recovering a board. RCW and PBL configuration. DDR and SerDes configuration. DDR and SerDes validation. U-Boot and Kernel debug For all of them and every activity involving real hardware, a link is needed nevertheless is a very straightforward process that is going to be crawled in this document.   Hardware List.   CodeWarrior TAP USB cable. USB A-Mini-B. CodeWarrior TAP TIP CWH-CTP-CTX10-YE. COP connector. CodeWarrior TAP Base Unit. CWH-CTP-BASE-HE. Host computer. Processor: Windows® OS: Intel® Pentium® 4 processor, 2 GHz or faster, Intel® Xeon™, Intel® Core™, AMD Athlon™ 64, AMD Opteron™, or later Linux® OS: 1.8 GHz Intel® Pentium® class processor (or better). 64-bit host OS required. Operating System: Microsoft® Windows 7 64-bit Microsoft® Windows 10 64-bit RHEL 7.8, 8.2 64-bit CentOS 7.8, 8.2 64-bit Ubuntu 16.04 64-bit Ubuntu 18.04 64-bit Ubuntu 20.04 64-bit Fedora 31 64-bit Mint 19.3 64-bit Memory. At least 2 GB of RAM At least 3 GB of free disk space NXP Reference Board featuring. LS2088A. LS1012A. LS1043A. LS1088A. LS1046A.   Power-up set-up.   Connect debugger and target's end to each other, while both of them are powered off. Connect TAP TIP multipin connector to TAP multipin socket pushing them.     Ribbon cable red side has to be on TIP pin 1 side and Target COP pin 1 side, look for CPU/Processor silkscreen and pin 1 label. See below examples.            Note that CPU JTAG silkscreen label is in the red box, but also may be visible the 1 label. Power up CWTAP. The most efficient way to set up CWTAP is using USB cable, due to can be both powered and communicated with just one cable. Connect USB to Host PC and wait for TX LED to go green blinking.     If communication is directly to host, considerate that you'll be joined into a private network and you will not have internet access. Power up Target. Connect target to DC supply and turn on power switch and press reset button (needed for boards which don't have a power switch). Create a connection in CodeWarrior.   Open CodeWarrior previously previously set up and with a workspace selected. Make sure that Target Connections window is visible, if not, look for it in Window > Show view > Other.   Every target connection desired has to be based on CW predefined board connections. Predefined connections are processor oriented and have a default configuration, you cannot and should not override this values, e.g., MAC field for TAP probe, you should duplicate and then customize it. Click on the reference board that you have, then duplicate, name new target and save.     Double click or click edit to enter TAP MAC value. Settings are initialized based on the duplicated board, it's recommended to just update MAC. Click on look for probes, select the one that matches your MAC and save.     Save. Serial number field is updated and you are notified of unsaved changes, is the asterisk at the left of your duplicate name, save (ctrl + s) and you may close the connection data is done now.     Open a project or create a new one. I created a new project to simply read RCW inside NOR Flash Bank 0 of LS1043ARDB following the below process.         Then, open Connections View to test the new connection based on custom connection data created before. Click on recheck connection button (green play button) and connection status should change from no-link (connection button right side) to connection working.     Diagnose connection.   Go to Target Connections view and click diagnose connection, Connection Diagnostics view should be popped up and log different tests to ensure that there is a target connection and SOC modules are accessible.     At this point, the connection is made and is already tested, but in this document, RCW will also be dumped into our project just to work ourselves with the connection already made. Under Component Inspector view go to Import tab, select Import From Target and click Read from target.     Results are display in text box as: RCWSR registers were successfully read from the target and imported! RCWSR1:0x08100010 RCWSR2:0x0A000000 RCWSR3:0x00000000 RCWSR4:0x00000000 RCWSR5:0x14550002 RCWSR6:0x80004012 RCWSR7:0xE0025000 RCWSR8:0xC1002000 RCWSR9:0x00000000 RCWSR10:0x00000000 RCWSR11:0x00000000 RCWSR12:0x00038800 RCWSR13:0x00000000 RCWSR14:0x00001101 RCWSR15:0x00000096 RCWSR16:0x00000001 That should save a connection to a CWTAP to reuse with that same MAC intended to a any RDB that features the selected processor. Later on you can recover LS Series processors, flash, configure or validate a board. Please ask any question you may have. Best regards, Joseph

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.
