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.

How to use UART2 instead of UART1 on LS1043ARDB/LS1046ARDB.   1. Compile PBL binary from RCW source file 2. Compile U-Boot binary 3. Compile TF-A binaries (bl2_.pbl and fip.bin) 4. Program TF-A binaries on specific boot mode     1-COMPILE PBL BINARY FROM RCW SOURCE FILE   You have to create a new directory to compile the binaries that you need to create a TF-A binary You need to compile the rcw_<boot_mode>.bin binary to build the bl2_<boot_mode>.pbl binary.   Clone the rcw repository and compile the PBL binary.   1. $ git clone https://github.com/nxp-qoriq/rcw 2. $ cd rcw 3. $ cd ls1043ardb 4. $ make   Inside the directory called “RR_FQPP_1455” you can see some binaries with the next nomenclature: rcw_<freq>.bin Where “freq” is the frequency in MHz of the processor, the values of the frequency are 1200MHz, 1400MHz, 1500MHz, and 1600MHz   2-COMPILE U-BOOT BINARY You need to compile the u-boot.bin binary to build the fip.bin binary. Clone the U-boot repository and compile the U-Boot binary for TF-A   1. $ git clone https://github.com/nxp-qoriq/u-boot 2. $ cd u-boot 3. $ git checkout -b LSDK-21.08 LSDK-21.08 4. $ export ARCH=arm64 5. $ export CROSS_COMPILE=aarch64-linux-gnu- 6. $ make distclean 7. $ nano configs/ls1043ardb_tfa_defconfig 7.1 change the bootargs "console=ttyS0,115200" for "console=ttyS1,115200" 7.2 add "CONFIG_CONS_INDEX=2 7. $ make ls1043ardb_tfa_defconfig 8. $ make   3 Compile TF-A binaries (bl2_.pbl and fip.bin) 1. $ git clone https://github.com/nxp-qoriq/atf 2. $ cd atf 3. $ git checkout -b LSDK-21.08 LSDK-21.08 4. $ export ARCH=arm64 5. $ export CROSS_COMPILE=aarch64-linux-gnu- 6. $ nano plat/nxp/common/include/default/ch_3_2/soc_default_base_addr.h 6.1 Change the line "#define NXP_UART_ADDR 0x021C0000" for "#define NXP_UART_ADDR 0x021D0000" 6.2 Change the line "#define NXP_UART1_ADDR 0x021D0000" for "#define NXP_UART_ADDR 0x021C0000" 7. $ nano plat/nxp/common/include/default/ch_2/soc_default_base_addr.h 7.1 Change the line "#define NXP_UART_ADDR 0x021C0500" for "#define NXP_UART_ADDR 0x021C0600" 7.2 Change the line "#define NXP_UART1_ADDR 0x021C0600" for "#define NXP_UART_ADDR 0x021C0500"   The compiled BL2 binaries, bl2.bin and bl2_<boot mode>.pbl are available at atf/build/ls1043ardb/release/. NOTE: For any update in the BL2 source code or RCW binary, the bl2_<boot mode>.pbl binary needs to be recompiled   3.1 HOW TO COMPILE BL2 BINARY To compile the BL2 binary without OPTEE: make PLAT=<platform> bl2 BOOT_MODE=<boot_mode> pbl RCW=<path_to_rcw_binary>/<rcw_binary_for_specific_boot_mode> To LS1043ARDB for SD boot: make PLAT=ls1043ardb bl2 BOOT_MODE=sd pbl RCW=<path_to_rcw_binary>/<rcw_freq.bin> To LS1043ARDB for NOR boot: make PLAT=ls1043ardb bl2 BOOT_MODE=nor pbl RCW=<path_to_rcw_binary>/<rcw_freq.bin> To LS1043ARDB for NAND boot: make PLAT=ls1043ardb bl2 BOOT_MODE=nand pbl RCW=<path_to_rcw_binary>/<rcw_freq.bin>   3.2 HOW TO COMPILE FIP BINARY   To compile the FIP binary without OPTEE and trusted board boot: $make PLAT=<platform> fip BL33=<path_to_u-boot_binary>/u-boot.bin   For LS1043ARDB: $make PLAT=ls1043ardb fip BL33=<path_to_u-boot_binary>/u-boot.bin   The compiled BL31 and FIP binaries ( bl31.bin, fip.bin ) are available at atf/build/ls1043ardb/release/. For any update in the BL31, BL32, or BL33 binaries, the fip.bin binary needs to be recompiled.   4 Program TF-A binaries on specific boot mode For that step you can use a tftp server, but it is easier with a USB formatted on FAT32.   You have to put the files “ bl2_<boot_mode>.pbl” and “fip.bin” in the usb and follow the steps to your boot mode.   4.1 Program TF-A binaries on IFC NOR flash For LS1043A, the steps to program TF-A binaries on IFC NOR flash are as follows:   1. Boot the board from the default bank. 2. Under U-boot prompt: => usb start 3. Flash bl2_nor.pbl: => fatload usb 0:1 $load_addr bl2_nor.pbl a. Alternate bank: => protect off 64000000 +$filesize && erase 64000000 +$filesize && cp.b $load_addr 64000000 $filesize b. Current bank: => protect off 60000000 +$filesize && erase 60000000 +$filesize && cp.b $load_addr 60000000 $filesize 4. Flash fip.bin: => fatload usb 0:1 $load_addr fip.bin a. Alternate bank: => protect off 64100000 +$filesize && erase 64100000 +$filesize && cp.b $load_addr 64100000 $filesize b. Current bank: => protect off 60100000 +$filesize && erase 60100000 +$filesize && cp.b $load_addr 60100000 $filesize 5. Reset your board: a. Alternate bank: cpld reset altbank b. Current bank: cpld reset   4.2 Program TF-A binaries on NAND flash   1. Boot the board from the default bank. 2. Under U-boot prompt: => usb start 3. Flash bl2_nand.pbl to NAND flash: => fatload usb 0:1 $load_addr bl2_nand.pbl => nand erase 0x0 $filesize;nand write $load_addr 0x0 $filesize; 4. Flash fip_uboot.bin to NAND flash: => fatload usb 0:1 $load_addr fip.bin => nand erase 0x100000 $filesize;nand write $load_addr 0x100000 $filesize; 5. Reset your board: => cpld reset nand   4.3 Program TF-A binaries on SD card   To program TF-A binaries on an SD card, follow these steps:   1. Boot the board from the default bank. 2. Under U-boot prompt: => usb start 3. Flash bl2_sd.pbl to SD card: => fatload usb 0:1 $load_addr bl2_sd.pbl => mmc write $ load_addr 8 A1 4. Flash fip.bin to SD card: => fatload usb 0:1 $load_addr bl2_sd.pbl => mmc write $load_addr 800 A1 5. Reset your board: => cpld reset sd Now the console should be out from UART2 port of the board.  

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

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.

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.

The VPP platform is an extensible framework that provides out-of-the-box production quality switch/router functionality. This document introduces Vector Packet Processing(VPP), creating VPP IPsec configuration scripts, building VPP v20.05 in LSDK 20.12, executing VPP IPsec on LS1046ARDB and LS2088ARDB platforms

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'.
