Getting Started with the FRWY-LS1046A

2. Get Software

3. Build, Run

Boot Options

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.

Requirement for build and Secure Root Key generation

Build LSDK 19.09 as per instructions from LSDK User Guide. 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:

• For SD-boot mode:

  $ vi rcw_1600_sdboot_sben.rcw
BOOT_HO=0
SB_EN=1

• Build SD secure firmware:

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

• Build QSPI secure firmware:

  $ 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

Procedure to run secure boot

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

1. Check SNVS state:

   =>md 0x1e90014
002b0088

   Note:

   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

   Now you can see ‘0’ in second nibble.

5. Check for parity error:

   =>md 0x1e80024
00000000

   Note:

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

Program SFP registers

1. Get SRK Key from build path:

   $ cat packages/apps/cst/srk_hash.txt

2. SRK (Public Key) 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

   Note:

   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

   Note:

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

Validation of Secure Boot

Switch Setting

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

Now boot the board.

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

At linux, check SEC_MON register whether Board is booted in Secure mode:

SD card preparation

Flashing the signed SD boot image commands:

Flashing the signed qspi boot image commands:

Once SD-card is ready, plug the console of the board to the X86 machine/Laptop and open the minicom using:

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

• A - Serial Device: /dev/ttyUSB0
• B - Lockfile Location: /var/lock
• C - Callin Program:
• D - Callout Program:
• E - Bps/Par/Bits: 115200 8N1
• F - Hardware Flow Control: No
• G - Software Flow Control: No

Save and exit from 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. Program the secure firmware to flash at 0x0:
=>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

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

The Jupyter Notebook is an open source web application that you can use to create and share documents that contain live code, equations, visualizations, and text. Its flexible interface allows users to configure and arrange workflows in data science, scientific computing, computational journalism and machine learning.

Advantages of Jupyter Notebook

• Offload work: On LS platform, one can deploy Jupyter Notebook and access it from web browser, so that LS board won’t get heavy running Python itself.
• Ease in implementation and solve problems: With a Jupyter Notebook, you can view code, execute it, and display the results directly in your web browser.
• Tutorial and documentations: Jupyter enables the combination of code with more detailed documentation and results. This can be effective for multiple purposes, like with working on creating a AI/ML model, including tutorials which you might have already come across.
• Access to shell: Jupyter notebook also provides access to terminal over the web browser, and one can modify the files on go, if needed, without getting worried about the console or board access or to switch the screen in between.

Configure Jupyter notebook on LS Platform

Some of the packages to be download:

Run the below command with user permission on LS platform to start jupyter notebook:

Output:

VNC Remote Desktop

Virtual network computing (VNC) is a type of software that makes remote control of a computer possible. 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.

Configure VNC server on LS Platform

Some of the packages to be download:

Set configuration and password for VNC.

Run the below command with user permission on LS platform to start vncserver:

This server can be enabled to start automatically. On FRWY-LS1046A console issue:

Connection to FRWY-LS1046A vncserver is possible using:

TigerVNC

TigerVNC is a high-performance, platform-neutral implementation of VNC (Virtual Network Computing), a client/server application that allows users to launch and interact with graphical applications on remote machines.

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

Advantages of TigerVNC

• Virtual display with development environment: LS board supports VNC server, which will provide desktop experience similar as x86, with support of basic tools like GMAC, terminal, web browser, file manager etc.
• 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.
