Update to newer build root newer version?

[fllay]

is there a way to upgrade this build root to newer version?

[jmfriedt]

Depending on how familiar you are with Buildroot ... I have started backporting https://github.com/trabucayre/redpitaya which is functional with the latest BR on a Zynq7010 similar to that of the RedPitaya. I am not in the lab this week to test, will let you know when the port is complete. Thank you for your interest in this project and reminding that it is out of date.

This branch was a try, in early 2023 to update this repository with a more recent buildroot.
Using redpitaya repository is not enough:

• PlutoSDR requires to have the gateware loaded at boot time,
• rootfs image is located into a flash chip with requirements to read dtb, rootfs, etc.
• lot of init scripts are mandatory to configure USB as serial+network interface to avoid bricking the board

The error here was to try to have something totally similar to ADi's repository: it's really a nightmare to bump the version due to the webserver and (lot of) associated files. The best way (I think) is to reduce complexity by just having bare minimal files/packages.

Thank you for the answer. Now I stuck at build root installation. It said that it requires kernel 4.14 so I plan to modify

BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https://github.com/analogdevicesinc/linux.git"
BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="c2041af164e263d852897cf90edb5cca9f677579"

to get 2018_R2 branch. Is that enough? Or I will face other errors? To my understanding, I need to follow the step in the tutorial

• build PL to get bit file (I follow the tutorial and I got the bit file)
• build the driver (I will get both static and dynamic lib ). In order to do this, I need a build root environment to cross compile the driver and I stuck here.
• build an application. Again, I need the build root environment.

I think that I just make dfu_frm and it will give me the firmware and dfu that I need.

BTW, I try to install ubuntu 18.04 on my two years old machine but keyboard and trackpad don't work. Ubuntu 18.04 is too old.

Update :

After I switch to Phoenix branch, I manage to the last point but I got the error

However, it seems to make everything ok. until the last step make dfu_frm and the error

which I think due to build root was not complete. Any idea on this?

BTW the build root script seems to have a problem with this repo

https://github.com/analogdevicesinc/plutosdr_scripts

I have to git clone it manually. Then everything is ok except that partition table error.

Hi,

I missed this thread for a while...

The https://github.com/oscimp/PlutoSDR/tree/bma_pluto branch is working with Buildroot 2024.11.1.

@jmfriedt: Do we merge PlutoSDR with oscimp_br2_external ? And then, support the coming 2025.11.1 ?

TODO:

• README
• minimal example for plutosdr

[jmfriedt]

I think there was a good reason why trabucayre wanted to keep PlutoSDR separate from oscimp_br2_external... but I cannot remember! But of course upgrading to a newer BR release is welcome.

[trabucayre]

Yes: upgrading Buildroot and all softwares is relevant. I think a big cleanup to removes all html stuff and only keeping packages, configs and scripts is required to simplify futur updates.

oscimp_br2_external is a generic repo with customization for boards, some packages (more or less temporary stored in this repo before mainline when possible).
PlutoSDR has a clear focus on a specific board with every mandatories packages and scripts. It's more clear for users and theoretically more easy to maintain
