启动选项

By default, the FRWY-LS1046A board comes preloaded with an LSDK composite firmware image. You can deploy Ubuntu userland on the board; however, due to limited NOR flash memory (64 MB), you need to use an external memory device, such as a micro-SD card or USB mass storage device for storing the LSDK images.

构建和生成安全根密钥的要求

按照《LSDK用户指南》中的说明构建LSDK 19.09。On LSDK19.09 build source path,

Download and untar the flexbuild 1909 tar file.

• Build source path:

  $ cd flexbuild_lsdk1909_update_221019

• Set environment for build:

  $ source setup.env

• Compile CST application:

  $ flex-builder -c cst -a arm64

• Enable secure boot in RCW if not enabled:

  $ cd packages/firmware/rcw/ls1046afrwy/NN_NNQNNPNP_3040_0506

Based on the desired use case, user can enable the specific rcw and compile images:

• 对于SD引导模式：

  $ vi rcw_1600_sdboot_sben.rcw
BOOT_HO=0
SB_EN=1

• 构建SD安全固件：

  $ flex-builder -i mkfw -m ls1046afrwy -b sd -s

• 构建QSPI安全固件：

  $ flex-builder -i mkfw -m ls1046afrwy -b qspi -s

• Check SRK Key from build path:

  $ cat packages/apps/cst/srk_hash.txt

• Build secure bootpartition:

  $ flex-builder -i mkbootpartition -a arm64 -m ls1046afrwy -s
  

• All the images for preparing card will be in the build path.

  $ cd build/images

运行安全引导的过程

With nonsecure firmware Power ON the board and stop at U-Boot.

1. Check SNVS state:

   =>md 0x1e90014
002b0088

   注：

   The second nibble indicates that the OTPMK is not blown.

2. Raise POVDD by executing below two commands:

   =>mw 0x2320000 80000000
=>mw 0x2320008 f01c0000

3. Program OTPMK:

   =>mm 0x01E80234
01e80234: 00000000 ? 11111111
01e80238: ffffffff ? 22222222
01e8023c: ffffffff ? 33333333
01e80240: ffffffff ? 44444444
01e80244: ffffffff ? 55555555
01e80248: ffffffff ? 66666666
01e8024c: ffffffff ? 77777777
01e80250: ffffffff ? 88888888
01e80254: 00000000 ? .

4. Check SNVS state:

   =>md 0x1e90014
00290080

   现在您可以在第二个半字节中看到“0”。

5. Check for parity error:

   =>md 0x1e80024
00000000

   注：

   Parity error state should be all zero. 非零值表示奇偶校验错误，请重写OTPMK值，并且交叉检查POVDD是否正确地提高。

设定SFP寄存器

1. 从构建路径中获取SRK密钥：

   $ cat packages/apps/cst/srk_hash.txt

2. SRK (公钥) Hash：

   43b38d3660ddf23067842974875f8af9ecfa2c3ad9d243abe6f4e18448eee0b7

   => mm 0x1e80254
01e80254: 00000000 ? 368db343
01e80258: 00000000 ? 30f2dd60
01e8025c: 00000000 ? 74298467
01e80260: 00000000 ? f98a5f87
01e80264: 00000000 ? 3a2cfaec
01e80268: 00000000 ? ab43d2d9
01e8026c: 00000000 ? 84e1f4e6
01e80270: 00000000 ? b7e0ee48
01e80274: 00000000 ? .

3. Check for parity error:

   =>md 0x1e80024
00000000

   注：

   Parity error state should be all 0. Non-zero value indicate parity error. Please rewrite OTPMK value and cross check POVDD is raised properly.

4. Blow the OTPMK to fuses if no parity error is found:

   =>mw 1e80020 0x02000000

   注：

   The fuse programming is permanent so make sure there is no parity error before running the above command.

Validation of Secure Boot

开关设置

After flashing image into SD card, insert the SD-card to board, and make sure the switch setting for sd/qspi respective booting mode:

QSPI NOR boot : 0_0100_0100_0
SD boot : 0_0100_0000_0

现在启动板。

On U-Boot log, you should be able to see “validating secure boot” and “esbc_validate command successful”.

在linux上，检查SEC_MON寄存器是否以安全模式启动板：

root@localhost:~# busybox devmem 0x1e90014
0x00AD0080

SD card preparation

Flashing the signed SD boot image commands:

$ flex-installer -f firmware_ls1046afrwy_uboot_sdboot_secure.img -b
>bootpartition.tgz< -r >rootfs.tgz< -m ls1046afrwy -d >/dev/sdx<

Flashing the signed qspi boot image commands:

$ flex-installer -b >bootpartition.tgz< -r >rootfs.tgz< -m ls1046afrwy -d >/dev/sdx<

SD卡就绪后，将板控制台插入X86机器/笔记本电脑，然后使用以下方法打开minicom：

$ sudo minicom -sw

Make sure the minicom setting should be same as below output:

• A - 串行设备：/dev/ttyUSB0
• B - 锁定文件位置：/var/lock
• C - 呼入程序:
• D - 呼出程序:
• E - Bps/Par/位：115200 8N1
• F - 硬件流控制：否
• G - 软件流控制：否

保存并退出minicom

Flashing the qspi secure firmware steps:

1. Unplug the SD card from Linux pc and insert in to FRWY-LS1046A board, stop at U-Boot follow below steps.
2. 将安全固件编程为以0x0刷新：
=>ext2load mmc 0:x 0xa0000000 firmware_ls1046afrwy_uboot_qspiboot_secure.img
=>sf probe 0:0
=>sf erase 0x0 +$filesize
=>sf write 0xa0000000 0x0 $filesize
=>reset

This demo shows the compute power of the FRWY-LS1046A, with 24,000 data points processed and pushed to a local database per minute.. The user can choose from among 400 simulated refrigerators to check internal temperature, external temperature and deviation from set-point. The gateway will flag any refrigerator that is not performing within the specified range of temperature. A local database is used to check past performance up to 24 hours.

Jupyter Notebook

Jupyter Notebook是一个开源Web应用程序，可用于创建和共享包含实时代码、方程式、可视化效果和文本的文档。Its flexible interface allows users to configure and arrange workflows in data science, scientific computing, computational journalism and machine learning.

Jupyter Notebook的优势

• 卸载工作：在LS平台上，您可以部署Jupyter Notebook并从网络浏览器访问它，这样LS板就不会因为运行Python而本身负担加重。
• 易于实施并解决问题：使用Jupyter Notebook，可以在Web浏览器中直接查看、执行代码并显示结果。
• 教程和文档：Jupyter使代码与更详细的文档和结果相结合。这对于多种目的可能是有效的，例如与创建AI/ML模型有关，包括您可能已经遇到的教程。
• 访问shell：Jupyter笔记本电脑还可以通过web浏览器访问终端，如果需要，用户可以随时修改文件，而不必担心控制台或主板的访问，也不必在两者之间切换屏幕。

VNC Remote Desktop

虚拟网络计算(VNC)是一种可对计算机进行远程控制的软件。It allows a user to view the desktop display of another computer remotely, and control the computer over the network. TigerVNC is a high-performance, platform-neutral implementation of VNC.

VNC presents a graphical desktop (Gnome or LXDE) running on the FRWY-LS1046A. The default desktop shipped with the FRWY-LS1046A is the LXDE desktop environment.

在LS平台上配置VNC服务器

Some of the packages to be download:

apt-get install tigervnc-standalone-server
apt-get install lxde-common
apt-get install openbox-lxde-session
apt-get install emacs

设置VNC的配置和密码。

在LS平台上使用用户权限运行以下命令以启动vncserver：

/usr/bin/perl /usr/bin/vncserver -localhost no -geometry 1024x768

此服务器可以自动启动。On FRWY-LS1046A console issue:

# systemctl enable vncserver-user@:1.service

Connection to FRWY-LS1046A vncserver is possible using:

$ vncviewer 192.168.99.1:1

TigerVNC

TigerVNC是VNC(虚拟网络计算)的高性能、与平台无关的实现，VNC是一种客户端/服务器应用程序，允许用户在远程计算机上启动图形应用程序并与之交互。

The default desktop shipped with FRWY-LS1046A is the LXDE desktop environment.

TigerVNC的优势

• 具有开发环境的虚拟显示： LS板支持VNC服务器，提供类似x86的桌面体验，支持GMAC、终端、web浏览器、文件管理器等基本工具。
• User-Friendly: User can modify the code directly opening the file in edit window, can copy paste the file from one location to another and even run video/camera stream.
• Highly secure: Full session encryption, multifactor authentication and many other security features.
• Support multiple devices: VNC is a light weighted tool and can be easily ported to any LS platform family.
• Multiple user support: One can create multiple users on LS platform with different access permission, so that each user can access the area they have to work on.
