The build system is currently supported on host PCs running Ubuntu 20.04 LTS 64-bit.
In order to build and deploy Linux to your ADSP-SC584-EZKIT 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 python
CrossCore Embedded Studio contains OpenOCD which is used to transfer U-Boot into RAM for the first initial boot of the device. The tools are created for 32-bit architecture and therefore requires a 32-bit libz package to run. Download and install it.
$ wget https://download.analog.com/tools/CrossCoreEmbeddedStudio/Releases/Release_2.10.0/adi-CrossCoreEmbeddedStudio-linux-x86-2.10.0.deb $ sudo dpkg -i ./adi-CrossCoreEmbeddedStudio-linux-x86-2.10.0.deb $ sudo apt install lib32z1
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
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
The example is fully contained in the Analog Devices Yocto Linux github repositories.
To install the sources: TODO: Make sure its the correct repo, branch, manifest file etc
$ mkdir ~/lnxdsp $ cd ~/lnxdsp $ 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-2.1.0 \ -m release-yocto-2.1.0.xml $ ./bin/repo sync
Yocto requires the environment to be configured before building is possible. A setup-environment script in the lnxdsp
folder contains all the required environment settings for your build target.
Source the setup script for your board:
$ source setup-environment -m adsp-sc584-ezkit
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.
You can build three different versions of the root filesystem; minimal, ramdisk and full. To build the example images invoke bitbake from within the build directory created previously.
$ bitbake adsp-sc5xx-minimal $ bitbake adsp-sc5xx-ramdisk $ 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
Copy the U-Boot & the init binary files to the /tftpboot directory, so that U-Boot can be ran from the board's RAM, along with the U-Boot loader file so that it can be uploaded to the target board:
$ cp tmp/deploy/images/adsp-sc584-ezkit/u-boot-sc584-ezkit /tftpboot/ $ cp tmp/deploy/images/adsp-sc584-ezkit/init-sc584-ezkit.elf /tftpboot/ $ cp tmp/deploy/images/adsp-sc584-ezkit/u-boot-sc584-ezkit.ldr /tftpboot/
Before installing the software on to the development board, ensure that the following cables are connected:
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
$ cd /opt/analog/cces/2.10.0/ARM/openocd/share/openocd/scripts $ sudo /opt/analog/cces/2.10.0/ARM/openocd/bin/openocd -f interface/<ICE>.cfg -f board/adspsc584_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

In a third console window launch GDB and type target extended-remote :3333
. This will make GDB to connect to the gdbserver on the local host using port 3333. Then, load the init file into RAM by typing load init-sc584-ezkit.elf
and run it by typing c
. Hit Ctrl+C to interrupt thereafter.
Terminal3: GDB

(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
U-Boot 2020.10 (Aug 23 2022 - 13:09:23 +0000) CPU: ADSP ADSP-SC584-0.1 (Detected Rev: 1.1) (spi flash boot) VCO: 450 MHz, Cclk0: 450 MHz, Sclk0: 112.500 MHz, Sclk1: 112.500 MHz, DCLK: 225 MHz OCLK: 150 MHz Model: ADI sc584-ezkit I2C: ready DRAM: 112 MiB MMC: Loading Environment from SPIFlash...

In the U-Boot console, set the IP address of the Host Linux PC that hosts the U-Boot loader file (u-boot-sc584-ezkit.ldr
) on TFTP.
Terminal1: minicom
=> setenv serverip <SERVERIP>
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.
Next, run the U-Boot update command to copy the U-Boot loader file from the host PC to the target board, and write it into flash:
=> run update
You will see an output similar to the one below:
=> run update Speed: 100, full duplex Using dwmac.3100c000 device TFTP from server 10.37.33.116; our IP address is 10.37.33.113 Filename 'u-boot-sc584-ezkit.ldr'.

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.
In order to boot Linux, the TFTP server should be setup as above and (for both NFS and RAM boot) a copy of the kernel image should be copied into the /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc584-ezkit/fitImage /tftpboot
For RAM boot a copy of the image containing the filesystem needs copied to the /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc584-ezkit/adsp-sc5xx-ramdisk-adsp-sc584-ezkit.cpio.xz.u-boot /tftpboot/ramdisk.cpio.xz.u-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
The root filesystem should then be copied to /romfs.
$ sudo tar -xf tmp/deploy/images/adsp-sc584-ezkit/adsp-sc5xx-full-adsp-sc584-ezkit.tar.xz -C /romfs
Next, on the target, from u-boot, run one of the following command:
=> run ramboot or => run nfsboot ...... ...... Starting Update UTMP about System Runlevel Changes... [ OK ] Started Update UTMP about System Runlevel Changes. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@ @@@@@@@@ @@@@@@@ @@@@@@@@ @@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Analog Devices Yocto Distribution www.analog.com www.yoctoproject.org adsp-sc584-ezkit login: root Password: adi root@adsp-sc584-ezkit:~#
