meta-adi-oran-bsp

This Yocto layer defines a board support package for all of ADI's Yocto-based O-RAN transceiver reference hardware designs. This includes firmware, the boot chain, a kernel, and drivers, but does not include the userspace software. (Software is provided in another layer.)

Machines

This layer defines the following machines:

adrv904x-rd-ru (a.k.a. Kerberos) is the O-RAN mid-band radio unit reference design for adrv904x-class transceivers.

Dependencies

oe-core (kirkstone) meta-arm

For FPGA platforms: meta-intel-fpga

For Intel FPGA platforms

Download & install the appropriate version of Quartus Programmer tool. Use the following install path: /opt/intelFPGA_pro/<version>. (You can download the programmer only from intel.com, e.g. v21.3 installer: QuartusProProgrammerSetup-21.3.0.170-linux.run)

21.3: adrv904x-rd-ru

Furthermore, please ensure that libncurses5 is installed: sudo apt-get install libncurses5

Licensing

Recipes are released under the MIT license. See COPYING.MIT for details.

Patches

Please submit any patches against the meta-adi-oran-sw layer to the O-RAN Support mailing list (pci_support@analog.com).

Building for adrv904x-rd-ru

Configure Yocto to build for adrv904x-rd-ru:

machine=adrv904x-rd-ru
echo "" >> conf/local.conf
echo "MACHINE = \"${machine}\"" >> conf/local.conf
echo "DISTRO = \"oran-distro\"" >> conf/local.conf

To build U-Boot, run: bitbake virtual/bootloader
To build the kernel, run: bitbake virtual/kernel
To build the root filesystem, run: bitbake adi-console-image -c image_cpio
To build SD image, run: bitbake adi-console-image

NOTE: Version strings for Linux and U-Boot to include ADI platform names set in steps 6 & 7 are optional.

System and image features

These images contain features can be enabled/disabled, such as INTEL-FPGA*,TF-A or Intel Remote System Update (RSU). This section will list features and document how they're enabled.

Note: INTEL_FPGA is enabled by default for machines with Intel FPGAs, like the Agilex on adrv904x-rd-ru. It is disabled by default on machines that do not have an FPGA.

Enable TF-A

Description: Enable or disable Arm trusted firmware in the boot image. This feature is enabled by default, to disable, set ADI_CC_TFA="0" in local.conf.

Relevant Variables: ADI_CC_TFA

Default Values: ADI_CC_TFA="1"

Enable Intel RSU

Description: Enable or disable Intel Remote Update in the system image. This feature is enabled by default, to disable, set ADI_CC_RSU="0" in local.conf.

Relevant Variables: ADI_CC_RSU

Default Values: ADI_CC_RSU="1"

Login with SSH key

Description: Configure SSH public key in the system image to allow ssh login. This feature is disabled by default, to enable, set ADI_CC_SSH_PUBKEY to the ssh public key to use in in local.conf.

Relevant Variables: ADI_CC_SSH_KEY_DIR

Default Values: ADI_CC_SSH_KEY_DIR=""

SD image size

Note: valid only for adrv904x-rd-ru

Set the SD image size by setting bootsize and rootfssize respectively, e.g.:

echo "BOOT_SIZE = \"256M\"" >> conf/local.conf
echo "ROOTFS_SIZE = \"1024M\"" >> conf/local.conf
