Access the console

The usual serial communication parameters are 115200 8-N-1 :

Baud rate	115200
Data	8 bits
Parity	None
Stop	1 bit
Flow control	None

Access the console on DEBUG serial port

The serial console can be accessed from two connectors. One is from the DEBUG port with the help of a TTL-to-USB serial cable (marked as DEBUG J24), another is from micro-A USB connector that gives access to the on-board serial-to-USB converter (marked as J22 VBUS_JLINK).

Using DEBUG on TTL-to-USB connector (DEBUG J24)

• For Microsoft Windows users: Install the driver of your USB TTL serial cable. FTDI-based ones are the most popular, have a look to this page to get the driver: http://www.ftdichip.com/Drivers/VCP.htm
• Be sure to connect a 3.3V compatible cable and identify its GND pin. Place it properly according to the silkscreen and connect the cable to the board (J24)
• For Microsoft Windows users: Identify the USB connection that is established, USB Serial Port should appear in Device Manager. The COMxx number will be used to configure the terminal emulator.
  
   
  • For Linux users: Identify the serial USB connection by monitoring the last lines of dmesg command. The /dev/ttyUSBx number will be used to configure the terminal emulator.

• Now open your favorite terminal emulator with appropriate settings

Using the micro-B USB connector (J22 VBUS_JLINK)

You can also access the serial console through the on-board serial-to-USB converter. In fact, the Segger J-LINK (Embedded Debugger) chip on the Evaluation Kit acts as a serial-to-USB converter and is loaded with a firmware that is able to talk USB-CDC protocol.

• For Microsoft Windows users: Install USB drivers for Atmel and Segger tools. No need to install a driver on any regular Linux distribution.
• Open JP21 to enable CDC serial connection
• If you need to enable J-Link connection (to program the board with J-Link Embedded Debugger), open JP20
• Connect the USB cable to the board (J22 VBUS_JLINK)
  • For Microsoft Windows users: identify the USB connection that is established
    EDBG Virtual COM Port should appear in Device Manager. The COMxx number will be used to configure the terminal emulator.
    
     
  • For Linux users: identify the USB connection by monitoring the last lines of dmesg command. The /dev/ttyACMx number will be used to configure the terminal emulator:

Create a SD card with the demo

You need a 1 GB SD card (or more) and to download the image of the demo. The image is compressed to reduce the amount of data to download. This image contains:

• a FAT32 partition with the AT91Bootstrap, U-Boot and the Linux Kernel (zImage and dtb).
• an EXT4 partition for the rootfs.

Multi-platform procedure

To write the compressed image on the SD card, you will have to download and install Etcher. This tool, which is an Open Source software, is useful since it allows to get a compressed image as input. More information and extra help available on the Etcher website.

• Insert your SD card and launch Etcher:

1. Select the demo image. They are marked as "SD Card image" in the demo table above.
   Note that you can select a compressed image (like the demos available here). The tool is able to uncompress files on the fly
2. Select the device corresponding to your SD card (Etcher proposes you the devices that are removable to avoid erasing your system disk)
3. Click on the Flash! button
4. On Linux, Etcher finally asks you to enter your root password because it needs access to the hardware (your SD card reader or USB to SD card converter)
5. then the flashing process begins followed by a verification phase (optional)

• Once writing done, Etcher asks you if you want to burn another demo image:

• Your SD card is ready!

Flash the demo

use SAM-BA 3.5.y onwards. You can download it here: SAM-BA 3.x release page.

Connect the USB to the board before launching SAM-BA

• Ensure SDCARD is not inserted and SPI, QSPI memories are not flashed
• Make sure that J13 DISABLE BOOT jumper is kept open
• press SW4 DIS_BOOT button to disable NAND Flash memory access
• Press SW3 nRST reset button to boot from on-chip Boot ROM
  • For Microsoft Windows users: verify that the USB connection is well established
    AT91 USB to Serial Converter should appear in Device Manager. If it shows a unknown device you need to download and install the driver: AT91SAM USB CDC driver
    
     
  • For Linux users: check /dev/ttyACMx by monitoring the last lines of dmesg command:
    

[172677.700868] usb 2-1.4.4: new full-speed USB device number 31 using ehci-pci

idVendor=03eb, idProduct=6124: from this message you can see it's Microchip board USB connection.

• release the SW4 DIS_BOOT button to reactivate NAND Flash memory access

Run script to flash the demo

• download the demo package for the board. They are marked as "Media type: NAND Flash" in the table above
• extract the demo package
• run your usual terminal emulator and enter the demo directory
• make sure that the sam-ba application is in your Operating System path so that you can reach it from your demo package directory
• for Microsoft Windows users: Launch the demo_linux_nandflash.bat file
• for Linux users: Launch the demo_linux_nandflash.sh file
• this script runs SAM-BA 3 and the associated QML sam-ba script (demo_linux_nandflash_usb.qml) with proper parameters
• when you reach the end of the flashing process (this will take a few minutes), the following line is written:

  -I- === Done. ===

• connect a serial link on DBGU and open the terminal emulator program as explained just above
• power cycle the board
• monitor the system while it's booting on the LCD screen or through the serial line

Build From source code

Setup ARM Cross Compiler

• Ubuntu:
  In Ubuntu, you can install the ARM Cross Compiler by doing:

  sudo apt-get install gcc-arm-linux-gnueabi
  export CROSS_COMPILE=arm-linux-gnueabi-
     

• Others:
  For others, you can download the Linaro cross compiler and setup the environment by doing:

  wget -c https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/arm-linux-gnueabi/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabi.tar.xz

  export CROSS_COMPILE=`pwd`/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-
     

Build AT91Bootstrap from sources

This section describes how to get source code from the git repository, how to configure with the default configuration, how to customize AT91Bootstrap based on the default configuration and finally to build AT91Bootstrap to produce the binary. take the default configuration to download U-Boot from NandFlash for example.

Get AT91Bootstrap Source Code

You can easily download AT91Bootstrap source code on the at91bootstrap git repository.

To get the source code, you should clone the repository by doing:

$ git clone git://github.com/linux4sam/at91bootstrap.git
Cloning into 'at91bootstrap'...
remote: Enumerating objects: 51, done.
remote: Counting objects: 100% (51/51), done.
remote: Compressing objects: 100% (32/32), done.
remote: Total 10880 (delta 20), reused 39 (delta 19), pack-reused 10829
Receiving objects: 100% (10880/10880), 4.03 MiB | 395.00 KiB/s, done.
Resolving deltas: 100% (8300/8300), done.
$ cd at91bootstrap/

Configure AT91Bootstrap

Assuming you are at the AT91Bootstrap root directory, you will find a configs folder which contains several default configuration files:

sam9x60ekqspi_uboot_defconfig
sam9x60eksd_uboot_defconfig
sam9x60eknf_uboot_defconfig

Tips: qspi means to read quad-SPI serial flash, sd means to read mmc card, nf means to read nand flash

You can configure AT91Bootstrap to load U-Boot binary from SD Card by doing:

$ make mrproper
$ make sam9x60eksd_uboot_defconfig

If the configuring process is successful, the .config file can be found at AT91Bootstrap root directory.

Customize AT91Bootstrap

If the default configuration doesn't meet your need, after configuring with the default configuration, you can customize it by doing:

$ make menuconfig

Now, in the menuconfig dialog, you can easily add or remove some features to/from AT91Bootstrap as the same way as kernel configuration.
Move to <Exit> with arrows and press this button hitting the Enter key to exit from this screen.

Build AT91Bootstrap

Then you can build the AT91Bootstrap binary by doing:

$ make

If the building process is successful, the final .bin image is build/binaries/at91bootstrap.bin.

Build U-Boot from sources

Getting U-Boot sources

Dedicated page on U-Boot wiki: http://www.denx.de/wiki/U-Boot/SourceCode

You can easily download U-Boot source code from Linux4SAM GitHub U-Boot repository:

• clone the Linux4sam GitHub U-Boot repository

     $ git clone git://github.com/linux4sam/u-boot-at91.git
     Cloning into 'u-boot-at91'...
     remote: Enumerating objects: 106920, done.
     remote: Counting objects: 100% (106920/106920), done.

     Resolving deltas: 100% (456142/456142), done.
     $ cd u-boot-at91
     

• The source code has been taken from the master branch which is pointing to the latest branch we use. If you want to use the other branch, you can list them and use one of them by doing:

     $ git branch -r
     origin/HEAD -> origin/master
     origin/master
     origin/u-boot-2012.10-at91
     origin/u-boot-2013.07-at91

     Switched to a new branch 'u-boot-2021.04-at91'
     

Cross-compiling U-Boot

Before compiling the U-Boot, you need setup cross compile toolchain in the section.

Latest versions of U-boot (2018.07 and newer) have a minimum requirement of 6.0 version of the GCC toolchain. We always recommend to use the latest versions.

Once the AT91 U-Boot sources available, cross-compile U-Boot is made in two steps: configuration and compiling. Check the Configuration chapter in U-Boot reference manual.

Go to the configs/ to find the exact target when invoking make.

The U-Boot environment variables can be stored in different media, above config files can specify where to store the U-Boot environment.

   # To put environment variables in nand flash:
   sam9x60ek_nandflash_defconfig
   # To put environment variables in SD/MMC card:
   sam9x60ek_mmc_defconfig
   # To put environment variables in qspi flash:
   sam9x60ek_qspiflash_defconfig

Here are the building steps for the SAM9X60-EK board:

# You can change the config according to your needs.
make sam9x60ek_mmc_defconfig
make

The result of these operations is a fresh U-Boot binary called u-boot.bin corresponding to the binary ELF file u-boot.

• u-boot.bin is the file you should store on the board
• u-boot is the ELF format binary file you may use to debug U-Boot through a JTag link for instance.

Build Kernel from sources

Getting Kernel sources

To get the source code, you have to clone the repository:

Configure and Build the Linux kernel

Now you have to configure the Linux kernel according to your hardware. We have two default configuration at91 SoC in arch/arm/configs

arch/arm/configs/at91_dt_defconfig
arch/arm/configs/sama5_defconfig

• at91_dt_defconfig: for SAM9 (ARM926) series chips
• sama5_defconfig: for SAMA5 series chips

At this step, you can modify default configuration using the menuconfig

$ make ARCH=arm menuconfig

Now, in the menuconfig dialog, you can easily add or remove some features. Once done, Move to <Exit> with arrows and press this button hitting the Enter key to exit from this screen.

Build the Linux kernel image, before you build you need set up the cross compile toolchain, check this section.

$ make ARCH=arm

Here are the reference pages for setting up a Yocto building environment: What You Need and How You Get It.

Step by step build procedure

here is a copy of the README procedure available directly in the meta-atmel layer. This file in the meta-atmel layer repository must be considered as the reference and the following copy can be out-of-sync.

starting with Linux4SAM 2021.04 release, the meta-atmel layer supports Yocto templates, so make sure you create a new build environment using oe-init-build-env

This layer provides support for Microchip microprocessors (aka AT91)

Using SAM-BA to flash components to board

NAND Flash demo - Memory map

Install SAM-BA software in your PC

In addition to the official SAM-BA pages on http://www.microchip.com, we maintain information about SAM-BA in the SoftwareTools page.

use SAM-BA 3.5.y onwards. You can download it here: SAM-BA 3.x release page.

Launch SAM-BA tools

• According to this section make sure that the chip can execute the SAM-BA Monitor.

In addition to the Qt5 QML language for scripting used for flashing the demos, most common SAM-BA action can be done using SAM-BA command line.

For browsing information on the SAM-BA command line usage, please see the Command Line Documentation that is available in the SAM-BA installation directory: doc/index.html or doc/cmdline.html .

SAM-BA includes command line interface that provides support for the most common actions:

• reading / writing to arbitrary memory addresses and/or peripherals
• uploading applets and using them to erase/read/write external memories

The command line interface is designed to be self-documenting.

The main commands can be listed using the "sam-ba --help" command:

SAM-BA Command Line Tool v3.5
Copyright 2018 Microchip Technology

Usage: ./sam-ba [options]
SAM-BA Command Line Tool

Options:
  -v, --version                          Displays version information.
  -h, --help                             Displays this help.
  -t, --tracelevel <trace_level>         Set trace level to <trace_level>.
  -L, --applet-buffer-limit <SIZE>       Set applet buffer limit to <SIZE>
                                         bytes (default 131072).
  -x, --execute <script.qml>             Execute script <script.qml>.
  -p, --port <port[:options:...]>        Communicate with device using <port>.
  -d, --device <device[:options:...]>    Connected device is <device>.
  -b, --board <board[:options:...]>      Connected board is <board>.
  -m, --monitor <command[:options:...]>  Run monitor command <command>.
  -a, --applet <applet[:options:...]>    Load and initialize applet <applet>.
  -c, --command <command[:args:...]>     Run command <command>.
  -w, --working-directory <DIR>          Set working directory to <DIR>.

Additional help can be obtained for most commands by supplying a "help" parameter that will display their usage.

For example "sam-ba --port help" will display:

Known ports: j-link, serial, secure

Command that take an argument with options (port, monitor, applet) will display even more documentation when called with "help" as option value.

For example "sam-ba --port serial:help" will display:

Syntax:
    serial:[<port>]:[<baudrate>]
Examples:
    serial                serial port (will use first AT91 USB if found otherwise first serial port)
    serial:COM80          serial port on COM80
    serial:ttyUSB0:57600  serial port on /dev/ttyUSB0, baudrate 57600

Configure NAND ECC

Using default PMECC parameters

when choosing the board variant with the -b parameter of SAM-BA, the default PMECC configuration for the NAND populated on the board is valid. You can verify its value by running the command that reads one byte in a dummy file (named test.bin in the following command):

# sam-ba -p serial -b sam9x60ek -a nandflash -c read:test.bin:0:1
Opening serial port 'ttyACM0'
Connection opened.
Detected memory size is 536870912 bytes.
Page size is 4096 bytes.
Buffer is 20480 bytes (5 pages) at address 0x0020a240.
NAND header value is 0xc1e04e07.
Supported erase block sizes: 256KB
Executing command 'read:test.bin:0:1'
Read 1 bytes at address 0x00000000 (100.00%)
Connection closed.

You can figure out that the default PMECC parameter for this sam9x60ek board is 0xc1e04e07.

: Note that if you connect a serial console to the SoC RomCode default UART, you can see even more details about the NAND ECC parameters given by the SAM-BA Applet:

Applet 'NAND Flash' from softpack 3.5 (v3.5).
Initializing NAND ioSet1 Bus Width 8
PMECC configuration: 0xc1e04e07
Sector size: 512
Sectors per page: 8
Spare size: 224
ECC bits: 8
ECC offset: 120
ECC size: 104
PMECC enabled
Buffer Address: 0x0020a240
Buffer Size: 20480 bytes
NAND applet initialized successfully.

If you want to change the default PMECC parameters you can simply specify another value on the SAM-BA command line with the -a nandflash argument as shown below:

# sam-ba -p serial -b sam9x60ek -a nandflash:help
Syntax: nandflash:[<ioset>]:[<bus_width>]:[<header>]
Parameters:
    ioset      I/O set
    bus_width  NAND bus width (8/16)
    header     NAND header value
Examples:
    nandflash                 use default board settings
    nandflash:2:8:0xc0098da5  use fully custom settings (IOSET2, 8-bit bus, header is 0xc0098da5)
    nandflash:::0xc0098da5    use default board settings but force header to 0xc0098da5
For information on NAND header values, please refer to SAMA5D4 datasheet section "12.4.4 Detailed Memory Boot Procedures".

By reading this in-line documentation we can specify the NAND PMECC parameter with this command:

# sam-ba -p serial -b sam9x60ek -a nandflash:::0xc1e04e07
Opening serial port 'ttyACM0'
Connection opened.
Detected memory size is 536870912 bytes.
Page size is 4096 bytes.
Buffer is 20480 bytes (5 pages) at address 0x0020a240.
NAND header value is 0xc1e04e07.
Supported erase block sizes: 256KB
Connection closed.
