Dear list

 

I followed the installation-instruction as given on the website for brickd and brickv. After the installation of both, I tried to connect to the attached HAT (version 1.9) using brickv.

The brickv started without any problems. But brickv wasn't able to connect with localhost:

An connection error occurred. Please check host, check port and ensure that Brick Daemon is running: [Errno 111] Connection refused

Trying to start brickd manually, I got the following information:

2024-07-01 16:50:12.151642 <I> <main_linux.c:369> Brick Daemon 2.4.5 started (pid: 2989, daemonized: 0)

Question:

• Do I have to install a brickd-version for 64bit manually? And if yes, which version would that be?
• Or do you have any other ideas and recommendations?

Browsing the forum, I found several issues like the current one:

• 12334-error-installing-brickd

But somehow, I didn't understand the solution.

Looking forward to any suggestions.

Cheers,

Currently there is a problem with Raspberry Pi 5 and more recent Linux kernel versions.

Please try the attached brickd version.

There will be a new release shortly. Sorry, for the long time it takes us to fix this problem.

Edit: Attachment deleted. Brick Daemon 2.4.6 has been released. Please install the official release instead.

Dear photron

Great, I just updated brickd using the update-tool of the Raspberry and it works.

Thank you very much for all your work.

Cheers,

Yvo
