Yocto Linux 2.2.0 Quickstart Guide for ADSP-SC594
This version is under development
The following instructions are for the ADSP-SC594-EZKIT development board (the EV-SC594-SOM System-on-Module (SOM) board attached to the EV-SOMCRR-EZKIT carrier board). For instructions for other processors and development boards please refer to Linux for ADSP-SC5xx Processors 2.2.0 (develop)
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-SC594-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
Installing CrossCore Embedded Studio
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_2.11.0/adi-CrossCoreEmbeddedStudio-linux-x86-2.11.0.deb $ sudo dpkg -i ./adi-CrossCoreEmbeddedStudio-linux-x86-2.11.0.deb $ sudo apt install lib32z1
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
Installing the Sources
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 ~/gxp $ cd ~/gxp $ 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 develop/yocto-2.2.0 \ -m develop-yocto-2.2.0.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 gxp folder contains all the required environment settings for your build target. Source the setup script for your board:
$ source setup-environment -m adsp-sc594-som-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.
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 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
Running U-Boot on the Board for the first time
Copy the U-Boot SPL and Proper elf files to the tftp directory:
$ cp tmp/deploy/images/adsp-sc594-som-ezkit/u-boot-spl-sc594-som-ezkit.elf /tftpboot/ $ cp tmp/deploy/images/adsp-sc594-som-ezkit/u-boot-proper-sc594-som-ezkit.elf /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 J13 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
- On the SOMCRR-EZKIT is a set of micro switches labelled SW1. These should all be set to the OFF position before continuing.
- The Power jumper JP1 on the EV-SC594-SOM board should be fitted so that it shorts the two pins closest to the edge. This will enable the routing of power from the SOMCRR-EZKIT.
- The BOOT MODE selector on the EV-SC594-SOM board should be turned to “0”.
The FAULT LED on the board will come on the first time the device is powered on. This is due to the
BootROM failing to find a valid image stored in QSPI. Once the QSPI has been correctly programmed this will no longer be the case.
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/2.11.0/ARM/openocd/share/openocd/scripts $ sudo /opt/analog/cces/2.11.0/ARM/openocd/bin/openocd -f interface/<ICE>.cfg -f board/ev-sc594-som.cfg
Where
<ICE>should be replaced withice1000orice2000depending on your hardware. When successful you should see a message similar to the console output belowOpen On-Chip Debugger (Analog Devices CCES 2.11.0) OpenOCD 0.10.0-gd1ba667 (2022-04-13-15:58) Licensed under GNU GPL v2 Report bugs to <processor.tools.support@analog.com> Info : only one transport option; autoselect 'jtag' adapter speed: 5000 kHz Info : halt and restart using CTI adspsc59x_a55_init Info : Listening on port 6666 for tcl connections Info : Listening on port 4444 for telnet connections Info : ICE-1000 firmware version is 1.0.2 Info : clock speed 5000 kHz Info : JTAG tap: adspsc594.adjc tap/device found: 0x0282e0cb (mfg: 0x065 (Analog Devices), part: 0x282e, ver: 0x0) Info : JTAG tap: adspsc594.cpu enabled Info : DAP adspsc594.cpu DPIDR indicates ADIv6 protocol is being used Info : adspsc594.cpu: hardware has 6 breakpoints, 4 watchpoints Info : starting gdb server for adspsc594.cpu on 3333 Info : Listening on port 3333 for gdb connections
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 U-Boot SPL into RAM by typing load u-boot-spl-sc594-som-ezkit.elf and hit Ctrl+C to interrupt.
Terminal3: GDB-

Booting the minimal image from QSPI
The U-Boot console is used to copy U-Boot (SPL and Proper), the minimal root filesystem image and the fitImage (which contains the kernel image and dtb file) into RAM and then write them to Flash. Copy the required files from <BUILD DIR>/tmp/deploy/images to your /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc594-som-ezkit/stage1-boot.ldr /tftpboot/ $ cp tmp/deploy/images/adsp-sc594-som-ezkit/stage2-boot.ldr /tftpboot/ $ cp tmp/deploy/images/adsp-sc594-som-ezkit/fitImage /tftpboot/ $ cp tmp/deploy/images/adsp-sc594-som-ezkit/adsp-sc5xx-minimal-adsp-sc594-som-ezkit.jffs2 /tftpboot
In the U-Boot console, set the IP address of the Host Linux PC that hosts the binary files on TFTP. Also, set the same address to the variable serverip
Terminal1: minicom-
=> setenv tftpserverip <SERVERIP> => setenv serverip <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:
=> run update_qspi_sc594
If your network does NOT support DHCP, in the U-Boot console configure the board IP address and remove the “run init_ethernet;” from the “update_spi_sc594” command.
=> setenv ipaddr <IPADDR>
=> edit update_spi_sc594
=> edit: <remove "run init_ethernet;" from here> sf probe ${sfdev}; sf erase 0 ${sfsize}; run update_spi_uboot; run update_spi_fit; run update_spi_rfs; sleep 3; saveenv
=> run update_qspi_sc594
After removing “run init_ethernet;” from update_spi_sc594, issue the “run update_qspi_sc594” command as above.
You should see output similar to the following.
=> run update_qspi_sc594

Booting Linux Using TFTP
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 and dtb file should be copied into the /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc594-som-ezkit/Image /tftpboot $ cp tmp/deploy/images/adsp-sc594-som-ezkit/sc594-som-ezkit.dtb /tftpboot
RAM Boot
For RAM boot a copy of the image containing the filesystem needs copied to the /tftpboot directory.
$ cp tmp/deploy/images/adsp-sc594-som-ezkit/adsp-sc5xx-ramdisk-adsp-sc594-som-ezkit.cpio.xz.u-boot /tftpboot/ramdisk.cpio.xz.u-boot
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
The root filesystem should then be copied to /romfs.
$ sudo tar -xf tmp/deploy/images/adsp-sc594-som-ezkit/adsp-sc5xx-full-adsp-sc594-som-ezkit.tar.xz -C /romfs
Booting into Linux from TFTP
Next, on the target, from u-boot, run one of the following command:
=> run ramboot
or
=> run nfsboot
......
