tezuka (name referenced to pluto) aims to be Universal Zynq/AD9363 firmware builder for plutosdr board and other boards: PlutoSDR, Pluto+, AntSDR (e200), LibreSDR.

Target of tezuka firmware is to maximize features of the board and integrate interesting projects on multi-target boards.

• Frequencies extension : 47.5Mhz-6Ghz
• Switch RX1/RX2 , TX1/TX2 seamlessly
• Complex 8bit mode to extend streaming bandwidth with host (14Mhz stable bandwidth through usb, 45MHz through GbE network)
• Audio gadget to be recognized as a soundcard (virtual cable not needed anymore)
• SD boot support : easy update, no risk of flashing, high amount of memory
• Include Maia-sdr transparently
• Publish basic information about the current state on local mqtt server
• Many other (need to be documented)

ADI launch PlutoSDR as a learning platform and it is ! But since 2 years, updates are mainly focused on expensive phaser (around 2500 Euros) product https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0566

Thus, official firmware updates are no longer focus on new features for SDR enthusiastic people.

• In release section (https://github.com/F5OEO/tezuka_fw/releases)
• Choose your right firmware depending on hardware and software, depending on name.
• Download your selected configuration on https://github.com/F5OEO/tezuka_fw/releases
• Unzip it. If you have a board with SD card, prefere this way for updating your firmware.

Use one the method :

• Flash on memory : paste pluto.frm to pluto drive and eject (detailed update procedure https://wiki.analog.com/university/tools/pluto/users/firmware)
• Write SD card : Copy contents of sdimg folder to a fresh FAT32 card formated.

A soon as firmware is updated, you could see a usb drive with parameters in config.txt (orginal parameters are described at (https://wiki.analog.com/university/tools/pluto/users/customizing)

• Satdump (https://github.com/F5OEO/SatDump)
• sdr++ (https://github.com/F5OEO/SDRPlusPlus)
• Soapy based software(https://github.com/F5OEO/SoapyPlutoPAPR)

Other great SDR software could use soon new features (SDRConsole, SDRAngel...), stay tuned !

Buildroot documentation has the list of required packages.

The following packages must be installed for building Maia-fw related code:

sudo apt install pkg-config libssl-dev libclang-dev

Now clone this repo and get buildroot

git clone https://github.com/F5OEO/tezuka_fw
cd tezuka_fw
./getbuildroot.sh

source sourceme.first
cd buildroot
# If you want to use the build in a Docker container, then run the following command here:
#  utils/docker-run
make pluto_maiasdr_defconfig && make

For a list all supported boards run (this might take a while):

make list-defconfigs

The items at the bottom are the ones supported by Tezuka.

Buildroot does not allow whitespaces in the PATH environment variable. On WSL several paths with whitespaces are added. The following script can be used to remove any path with whitespaces. It also deletes any leftover ':' at the end:

export PATH=$(echo $PATH | tr ':' '\n' | grep -v ' ' | tr '\n' ':' | sed 's/:$//')

If you encounter errors related to CMAKE policy version, it's because newer versions of CMAKE (3.27+) have stricter policy requirements. Setting CMAKE_POLICY_VERSION_MINIMUM=3.5 tells CMAKE to use policies from version 3.5 or newer, which helps maintain compatibility with older build scripts and dependencies that may not be fully compatible with the latest CMAKE policies. This is particularly important when building packages that haven't been updated to support newer CMAKE versions.

Run the build with:

CMAKE_POLICY_VERSION_MINIMUM=3.5 make
