Linux BSP Version

Ubuntu 18.04

Kernel 5.4.47

Released Image

• OS Support List (based on Ubuntu 18.04)

Download flex-installer

    $ wget https://www.nxp.com/lgfiles/sdk/lsdk2012/flex-installer && chmod +x flex-installer && sudo mv flex-installer /usr/bin

Build Environment on Host

If you don't have docker in your system, then you can follow the below  steps to install docker and run it first.

Log in to a Docker registry

   $ docker login -u advcus -p iTk7Sy9OQVQCkN2FPKw=Om8mfwfZQqKi riscswacr.azurecr.io

Pull Ubuntu 18.04 from Azure Container Registry

   $ docker pull riscswacr.azurecr.io/u18.04-ls1046albv1:latest

Run/Create Docker Container

   $ docker run -it --name ${CONTAINER_NAME} --privileged -v ${WORK_SPACE}:/home/adv/flexbuild_lsdk2012:rw riscswacr.azurecr.io/u18.04-ls1046albv1 /bin/bash

Get BSP

Download BSP from Azure DevOps

    The following example shows how to download the Advantech LSDK flexbuilder from DevOps. (Execute in Docker container)

    For this example, a directory called adv-release-bsp is created for the project.

    $ cd adv-release-bsp
    $ git clone https://AIM-Linux@dev.azure.com/AIM-Linux/flexbuild_lsdk2012/_git/flexbuild_lsdk2012

Build Images

These commands are execute in Docker environment.

Composite Firmware

Type with QSPI, eMMC and SD

    $ cd flexbuild_lsdk2012
    $ source setup.env
    $ flex-builder -i mkfw -m ls1046ardb -b qspi
    $ flex-builder -i mkfw -m ls1046ardb -b emmc
    $ flex-builder -i mkfw -m ls1046ardb -b sd

Root File System

    $ flex-builder -i mkrfs -r ubuntu:main -a arm64

Boot Partition

    $ flex-builder -i mkbootpartition -a arm64

Flash Images

These operations process in linux local host

Bootable SD card :

    $ cd adv-release-bsp/flexbuild_lsdk2012/build/images/
    $ flex-installer -i pf -d /dev/sda
    $ flex-installer -f firmware_ls1046ardb_uboot_sdboot.img -b bootpartition_LS_arm64_lts_5.4_xxxxxxxxxxxx.tgz -r rootfs_lsdk2012_ubuntu_main_arm64.tgz -d /dev/sda

Rootfs and Boot-Partition in USB

    $ cd adv-release-bsp/flexbuild_lsdk2012/build/images/
    $ flex-installer -i pf -d /dev/sdx
    $ flex-installer -b bootpartition_LS_arm64_lts_5.4_xxxxxxxxxxxx.tgz -r rootfs_lsdk2012_ubuntu_main_arm64.tgz -d /dev/sdx

Boot Mode

QSPI Mode	MMC mode

Flash Image to eMMC

Step 1. Burn In Boot-Loader to QSPI Flash

    You need a bootable SD card (follow above section), and switch boot mode to SD mode.

    Insert your SD card and follow below flow in U-boot console.

   Set FTP Server IP

   $ setenv serverip 172.22.31.153

    Request IP Address

    $ dhcp

    Try to Ping FTP Server

    $ ping 172.22.31.153

    Load U-boot Firmware Image

    $ tftp $load_addr firmware_ls1046ardb_uboot_qspiboot.img

    Install Image to QSPI (32MB)

    $ sf probe 0:0
    $ sf erase 0 0x2000000 && sf write $load_addr 0 0x2000000

    Shutdown, unplug SD card, switch to QSPI mode, plugin the prepared USB disk and power on the board again.

    Boot into U-boot console again and flush the eMMC

    $ mmc erase 0 0x8000
    $ boot

    Boot into rootfs with USB disk

    Create FTP Temp Folder

    $ mkdir /media/mytftp
    $ cd /media/mytftp

    Request IP Address

    $ ifconfig fm1-mac9 up
    $ udhcpc -i fm1-mac9
    $ ping 172.22.31.153

    Download Images from FTP

    $ tftp -m binary 172.22.31.153 -c get "bootpartition_LS_arm64_lts_5.4_xxxxxxxxxxxx.tgz"
    $ tftp -m binary 172.22.31.153 -c get "firmware_ls1046ardb_uboot_emmcboot.img"
    $ tftp -m binary 172.22.31.153 -c get "rootfs_lsdk2012_ubuntu_main_arm64.tgz"

   Initial eMMC Partitions

    $ flex-installer -i pf -d /dev/mmcblk0

   Install Images

    $ flex-installer -f firmware_ls1046ardb_uboot_sdboot.img -b bootpartition_LS_arm64_lts_5.4_xxxxxxxxxxxx.tgz -r rootfs_lsdk2012_ubuntu_main_arm64.tgz -d /dev/mmcblk0

    * Finally, shutdown and restart after switch boot mode back to SD mode.

Program Boot-Loader

After flash eMMC complete (by flex-installer). If you want to update boot-loader only, just put composite firmware image in your tftp path and execute following commands.

    $ tftp $load_addr firmware_ls1046ardb_uboot_emmcboot.img
    $ mmc dev 0
    $ mmc write $load_addr 8 $IMAGE_SIZE

   * IMAGE_SIZE = tftp-download-size / 512 (block size)

Linux Kernel and Device Tree Update

Compile kernel and device tree first :

    $ flex-builder -c linux -a arm64

Copy image and dtb file to boot partition mount point :

    $ cp linux/arch/arm64/boot/Image ${boot_partition}
    $ cp linux/arch/arm64/boot/Image.gz ${boot_partition}
    $ cp linux/arch/arm64/boot/dts/freescale/fsl-ls1046a-rdb.dtb ${boot_partition}
