Yocto Linux 3.0.0 Quickstart Guide for ADSP-SC589 (EZKIT & MINI)
The following instructions are for the ADSP-SC589-EZKIT and ADSP-SC589-MINI development boards.
For instructions for other processors and development boards please refer to Linux for ADSP-SC5xx Processors 3.0.0
Setting Up Your Host PC
The build system is currently supported on host PCs running Ubuntu 20.04 LTS 64-bit.
Installing Required Packages
In order to build and deploy Linux to your ADSP-SC589-EZKIT or ADSP-SC589-MINI development board you will need to install the following packages on your host PC.
$ sudo apt-get update $ sudo apt-get install -y gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm u-boot-tools openssl curl tftpd-hpa python3 zstd liblz4-tool
Configuring TFTP Service
A TFTP server on the host is used to transfer images to the development board. Install and configure.
$ sudo vi /etc/default/tftpd-hpa #Replace the existing file with the following TFTP_USERNAME="tftp" TFTP_DIRECTORY="/tftpboot" TFTP_ADDRESS="0.0.0.0:69" TFTP_OPTIONS="--secure" #End of File $ sudo mkdir /tftpboot $ sudo chmod 777 /tftpboot $ sudo service tftpd-hpa restart
Configure Minicom
In order to communicate with the U-Boot bootloader, a UART connection must be made between the host PC and the development board. It is recommended that you use minicom to do this. Minicom must be configured to connect to U-Boot correctly.
On the host PC open a terminal and execute the following commands:
$ sudo apt-get install -y minicom $ sudo minicom -s +-----[configuration]------+ | Filenames and paths | | File transfer protocols | | Serial port setup | | Modem and dialing | | Screen and keyboard | | Save setup as dfl | | Save setup as.. | | Exit | | Exit from Minicom | +--------------------------+ # Select Serial port setup Set Serial Device to /dev/ttyUSB0 Set Bps/Par/Bits to 115200 8N1 Set Hardware Flow Control to No Close the Serial port setup option by press Esc Select Save setup as dfl Select Exit
/dev/ttyUSB0 might not correspond to the serial port of the board on every system. You can determine which /dev entry your board uses by running ls -l /dev/ttyUSB* twice, once when the serial port of the board is plugged in, and once when it isn't.
Installing the Sources
The example is fully contained in the Analog Devices Yocto Linux github repositories.
To install the sources:
$ mkdir ~/griffin $ cd ~/griffin $ mkdir bin $ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ./bin/repo $ chmod a+x ./bin/repo $ ./bin/repo init \ -u https://github.com/analogdevicesinc/lnxdsp-repo-manifest.git \ -b release/yocto-3.0.0 \ -m release-yocto-3.0.0.xml $ ./bin/repo sync
Building the Image
Preparing the buildtool
Yocto requires the environment to be configured before building is possible. A setup-environment script in the griffin folder contains all the required environment settings for your build target. Source the setup script for your board:
$ source setup-environment -m adsp-sc589-ezkit
or
$ source setup-environment -m adsp-sc589-mini
Sourcing the script will configure your build environment and create a build folder along with a local build configuration file. See the Yocto Manual for further details.
Note that the build environment needs to be sourced once only before building. If later working in a different terminal the setup-environment script should be sourced again. If sourcing the setup-environment script is done without specifying the machine Yocto will reuse the previous configuration settings and retain any changes made to the files in the conf folder.
Building the example
You can build two different versions of the root file system; minimal and full. To build the example images invoke bitbake from within the build directory created previously.
$ bitbake adsp-sc5xx-minimal $ bitbake adsp-sc5xx-full
When the build completes you will see a warning that the ELF binary has relocations in .text. It is OK to ignore this warning
Building a Linux distribution with Yocto is a significantly demanding process, both in CPU and network usage. A full build from scratch is estimated to take around 170 minutes for an 11th Gen Intel Core i5-11500T with 16 GB of RAM and a stable, fast Internet connection. This estimate can go up significantly for a poorer Internet connection or CPU resources, so set aside plenty of time for a clean build.
Building the SDK
The SDK will provide you with the cross toolchain needed to develop application for the target board, alongside various miscellaneous tools. Notably, it will provide you with OpenOCD and GDB, which you can use to run and flash U-Boot on the board.
The SDK can be built for the adsp-sc5xx-minimal image or the adsp-sc5xx-full image. To build the SDK for the adsp-sc5xx-minimal image invoke bitbake from within the build directory created previously.
$ bitbake adsp-sc5xx-minimal -c populate_sdk
or for the adsp-sc5xx-full image
$ bitbake adsp-sc5xx-full -c populate_sdk
When the build has completed you will find a set of files in the <BUILD_DIR>/tmp/deploy/sdk directory. For example, the minimal image on SC589-EZKIT:
$ ls tmp/deploy/sdk adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.host.manifest adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.sh adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.target.manifest adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.testdata.json
The adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.sh or adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-mini-toolchain-3.0.0.sh is a self-extracting archive containing the SDK.
Installing the SDK
Invoke the self-extracting archive.
It will default to installing to /opt/adi-distro/3.0.0 but gives you the option to select your own install folder during the installation.
For the minimal image on SC589-EZKIT
$ ./adi-distro-glibc-glibc-x86_64-adsp-sc5xx-minimal-cortexa5t2hf-neon-adsp-sc589-ezkit-toolchain-3.0.0.sh Analog Devices Inc Reference Distro (glibc) SDK installer version 3.0.0 ======================================================================= Enter target directory for SDK (default: /opt/adi-distro-glibc/3.0.0): You are about to install the SDK to "/opt/adi-distro-glibc/3.0.0". Proceed [Y/n]? y Extracting SDK................................................................................................................done Setting it up...done SDK has been successfully set up and is ready to be used. Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g. $ . /opt/adi-distro-glibc/3.0.0/environment-setup-cortexa5t2hf-neon-adi_glibc-linux-gnueabi
Your SDK is now installed.
Running U-Boot on the Board for the first time
It's always good practice to erase the contents of
/tftpboot/ before running and/or flashing a new build of U-Boot or Linux. You can do so by executing rm /tftpboot/* before proceeding
Copy the U-Boot binary & loader files to the tftp directory:
$ cp tmp/deploy/images/adsp-sc589-ezkit/u-boot-proper-sc589-ezkit.elf /tftpboot $ cp tmp/deploy/images/adsp-sc589-ezkit/u-boot-spl-sc589-ezkit.elf /tftpboot $ cp tmp/deploy/images/adsp-sc589-ezkit/stage1-boot.ldr /tftpboot $ cp tmp/deploy/images/adsp-sc589-ezkit/stage2-boot.ldr /tftpboot
or
$ cp tmp/deploy/images/adsp-sc589-mini/u-boot-proper-sc589-mini.elf /tftpboot $ cp tmp/deploy/images/adsp-sc589-mini/u-boot-spl-sc589-mini.elf /tftpboot $ cp tmp/deploy/images/adsp-sc589-mini/stage1-boot.ldr /tftpboot $ cp tmp/deploy/images/adsp-sc589-mini/stage2-boot.ldr /tftpboot
Before installing the software on to the development board, ensure that the following cables are connected:
- Board connected to network via ethernet cable using J14 connector.
- Board connected to host PC using USB micro cable, connected to USB/UART port on the development board
- Board connected to the ICE 1000 or ICE 2000 via the DEBUG port on the board
- ICE is also connected to host PC via USB mini cable
- ADSP-SC589-EZKIT only: The BOOT MODE selector on the board should be turned to “0”.
The console output from U-Boot and later on Linux will appear on the USB serial port configured in minicom earlier so open up minicom.
Terminal1: minicom$ sudo minicom
In a separate console launch OpenOCD and connect to the development board
Terminal2: OpenOCD$ sdk_usr=/opt/adi-distro-glibc/3.0.0/sysroots/x86_64-adi_glibc_sdk-linux/usr/ $ $sdk_usr/bin/openocd -f $sdk_usr/share/openocd/scripts/interface/<ICE>.cfg -f $sdk_usr/share/openocd/scripts/board/adspsc589_ezbrd.cfg
Where <ICE> should be replaced with ice1000 or ice2000 depending on your hardware. When successful you should see a message similar to the console output below

(gdb) c Continuing.
At this point U-Boot will now be running in RAM on your target board. You should see U-Boot booting in the minicom console (Terminal 1). Press a key to interrupt the boot process before the countdown terminates:
Terminal1: minicom (sc589-ezkit)-

Flash U-Boot to SPI Flash
In the U-Boot console, set the IP address of the Linux PC that hosts the U-Boot loader files (stage1-boot.ldr & stage2-boot.ldr) on TFTP.
Terminal1: minicom-
=> setenv serverip <SERVERIP> => setenv tftpserverip <SERVERIP>
To find the IP address of your host Linux PC you can issue the
ip addr command from the shell or console.
If your network supports DHCP, run:
=> dhcp
If your network does NOT support DHCP, run:
=> set ipaddr <ADDR>
Where <ADDR> is the IP address you want to assign.
If flashing a board that had been previously programmed, it's good to erase the whole flash before as sometimes previous U-Boot installations might leave remnants. You can do that by typing
⇒ sf probe ${sfdev}; sf erase 0 0x4000000 on the U-Boot prompt before proceeding to the following instructions
Next, run the U-Boot update command to copy the U-Boot loader files from the host PC to the target board, and write it into flash:
=> run update_spi_uboot_only
You will see an output similar to the one below:
=> run update_spi_uboot_only Speed: 1000, full duplex Using eth0 device TFTP from server 192.168.1.223; our IP address is 192.168.1.217 Filename 'stage1-boot.ldr'.

In order to store the serverip and the DHCP or otherwise assigned IP address of the board and have them available on next boot, you can run the following command:
=> saveenv
Saving Environment to SPIFlash... Erasing SPI flash...Writing to SPI flash...done
OK
At this point the U-Boot binary is stored in flash. You can now disconnect the ICE-1000 or ICE-2000 from the development board and make sure to switch the BMODE to position 1. You will only need to reconnect this if your board fails to boot and you need to re-follow these instructions.
Booting Linux
Booting Linux from SPI Flash
The ADSP-SC589-EZKIT and ADSP-SC589-MINI come equipped with 16 MiB of SPI Flash. There's the option of building the adsp-sc5xx-tiny image, after changing the Libc implementation from the default GNU to musl, to further reduce the image's size. Follow the guide in Boot from SPI Flash on the SC58x & SC573
Booting Linux Using SD Card
Formatting the SD Card
In order to use an SD Card with Linux we need to prepare it by formatting it in the correct format. This section of instructions requires you to correctly identify the SD Card and format the card. If you select the wrong drive you may cause irreversible damage to you Host PC. To format the SD Card, follow the commands below. The example code in this section assumes that the SD Card device is reported to be /dev/sdb. Ensure that you change these commands to use your device.
$ sudo fdisk /dev/sdb /* Create primary partition 1, 256M size*/ Command (m for help): n Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-3887103, default 2048): PRESS ENTER Last sector, +sectors or +size{K,M,G} (2048-3887103, default 3887103): PRESS ENTER /* Save partition */ Command (m for help): w
Format the SD card to EXT filesystem
$ sudo mkfs.ext2 /dev/sdb1
Writing the kernel and file system to the SD Card
Next, we need to copy the Linux file system and kernel image to the SD Card. We install this on to the SD Card by mounting the file system on to the local Host PC and copying the contents on to the SD Card. To allow the choice of booting using ramboot and sdcard boot we copy the ramboot image to the SD card as well as extract the minimal image to the SD card.
$ mkdir ~/mnt $ sudo mount -t ext2 /dev/sdb1 ~/mnt $ sudo mkdir ~/mnt/boot $ sudo cp tmp/deploy/images/adsp-sc589-ezkit/adsp-sc5xx-ramdisk-adsp-sc589-ezkit.cpio.xz ~/mnt/boot/ramdisk.cpio.xz.u-boot $ sudo cp tmp/deploy/images/adsp-sc589-ezkit/sc589-ezkit.dtb ~/mnt/boot/ $ sudo cp tmp/deploy/images/adsp-sc589-ezkit/fitImage ~/mnt/boot/ $ sudo tar -xf tmp/deploy/images/adsp-sc589-ezkit/adsp-sc5xx-minimal-adsp-sc589-ezkit.tar.xz -C ~/mnt $ sudo umount ~/mnt
or
$ mkdir ~/mnt $ sudo mount -t ext2 /dev/sdb1 ~/mnt $ sudo mkdir ~/mnt/boot $ sudo cp tmp/deploy/images/adsp-sc589-mini/adsp-sc5xx-ramdisk-adsp-sc589-mini.cpio.xz ~/mnt/boot/ramdisk.cpio.xz.u-boot $ sudo cp tmp/deploy/images/adsp-sc589-mini/sc589-mini.dtb ~/mnt/boot/ $ sudo cp tmp/deploy/images/adsp-sc589-mini/fitImage ~/mnt/boot/ $ sudo tar -xf tmp/deploy/images/adsp-sc589-mini/adsp-sc5xx-minimal-adsp-sc589-mini.tar.xz -C ~/mnt $ sudo umount ~/mnt
The file system and kernel image are now installed on to the SD Card. The SD Card can now be safely removed from the Host PC.
Booting Linux from the SD card
Insert the SD card to target board, and reset the board and enter into U-Boot
=> run sdcardboot or => run ramboot_emmc
The linux kernel will then boot up using the file system stored in SD card.
Booting Linux from USB Mass Storage
Formating USB stick
Frist step is to format USB stick to U-Boot supported formats.
To format the USB stick, follow the commands below. The example code in this section assumes that the USB device is reported to be /dev/sdb. Ensure that you change these commands to use your device.
$ sudo fdisk /dev/sdb /* Create primary partition 1, 256M size*/ Command (m for help): n Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-3887103, default 2048): PRESS ENTER Last sector, +sectors or +size{K,M,G} (2048-3887103, default 3887103): PRESS ENTER /* Save partition */ Command (m for help): w
Format the USB stick to EXT4 filesystem
$ sudo mkfs.ext4 /dev/sdb1
Writing kernel and rootfs image to USB stick
$ mkdir ~/mnt $ sudo mount -t ext4 /dev/sdb1 ~/mnt $ sudo mkdir ~/mnt/boot $ sudo cp tmp/deploy/images/adsp-sc589-ezkit/adsp-sc5xx-ramdisk-adsp-sc589-ezkit.cpio.xz ~/mnt/boot/ramdisk.cpio.xz.u-boot $ sudo cp tmp/deploy/images/adsp-sc589-ezkit/fitImage ~/mnt/boot/ $ sudo umount ~/mnt
or for SC598-mini
$ mkdir ~/mnt $ sudo mount -t ext4 /dev/sdb1 ~/mnt $ sudo mkdir ~/mnt/boot $ sudo cp tmp/deploy/images/adsp-sc589-mini/adsp-sc5xx-ramdisk-adsp-sc589-mini.cpio.xz ~/mnt/boot/ramdisk.cpio.xz.u-boot $ sudo cp tmp/deploy/images/adsp-sc589-mini/fitImage ~/mnt/boot/ $ sudo umount ~/mnt
Booting Linux from USB Mass Storage
To boot from ADSP-SC589-EZKIT run this commands in u-boot
setenv usbload 'ext4load usb 0 ${initramaddr} /boot/${initramfile}; ext4load usb 0 ${loadaddr} /boot/${imagefile};' setenv usbboot 'usb start; run usbload; run ramargs; bootm ${loadaddr} ${initramaddr};' run usbboot
To boot from ADSP-SC589-MINI there is need to disable emac0 device in u-boot device tree, as USB and ethernet port share same pin and can't run simultaneously. Inside Yocto directory type
devtool modify u-boot-adi
edit build/workspace/sources/u-boot-adi/arch/arm/dts/sc589-mini.dts by adding
&emac0 { status="disable"; };
To rebuild U-boot after modifications
devtool build u-boot-adi
Booting rootfs from USB Mass Storage
Follow the step how to setup USB stick in chapter above. Set environment variables in U-boot
setenv usbargs 'setenv bootargs root=/dev/sda1 rw rootfstype=ext4 rootwait earlycon=adi_uart,0x31003000 console=ttySC0,115200' setenv usbload 'ext4load usb 0 ${loadaddr} /boot/${imagefile};' setenv usbboot 'usb start; run usbload; run usbargs; bootm ${loadaddr};'
And type to boot
run usbboot
Now the rootfs is set to your USB stick and amount of space equals of size of partition on USB stick.
Booting Linux Using TFTP
In order to boot Linux, the TFTP server should be setup as above and a copy of the kernel image should be copied into the /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc589-ezkit/fitImage /tftpboot
or
$ cp tmp/deploy/images/adsp-sc589-mini/fitImage /tftpboot
NFS Boot
For NFS boot we use the Network File System which is stored in local Ubuntu Host. This is suggested when you do application development. To setup the NFS server:
$ sudo apt-get install nfs-kernel-server $ sudo vi /etc/exports #Add following commands /romfs *(rw,sync,no_root_squash,no_subtree_check) $ sudo mkdir /romfs/ $ sudo chmod 777 /romfs/ $ sudo service nfs-kernel-server start
We can verify that the NFS service is running by executing
$ sudo service nfs-kernel-server status
The output will indicate that the server is active, i.e.
● nfs-server.service - NFS server and services
Loaded: loaded (/lib/systemd/system/nfs-server.service; enabled; vendor preset: enabled)
Drop-In: /run/systemd/generator/nfs-server.service.d

If it's reported as inactive, wait a few moments and check the status again.
The root filesystem should then be copied to /romfs.
