Hello,

I work on a touch panel with raspberry pi cm4. Only the runtime needs to be run on it and it is used as an operating station. I installed pwrrt V5.9 and the problem occurs at "pwr start". The attached picture shows the response to "pwr start" and "rt_ini -i".
Is it necessary to install pwr V5.9 or is pwrrt V5.9 enough?
During the installation, I followed the "installation manual" and "designers guide".
Please advise how to solve the problem and start pwrrt.

Any help or advice is welcome!

Hi eiver,

You are trying to start the node raspberrypi on bus 517. So either this node is not configured on this bus in the directory volume, or it's not built or distributed.

If you it is configured in another bus you can change the bus in /etc/proview.cnf. Otherwise you can change the bus number in the BusConifg object, and node name in the NodeConfig object in the directory volume.

Hi Claes,

Thank you for your reply!

The problem is solved, but a new problem appears. In the attachment I am sending you the results when using the command "pwr start" and "rt_ini -i".

Please advise how to solve the problem.

When you have started with rt_ini you have to reset with

> source pwr_stop.sh

before you can start again.

Hi Claes,

Thank you for your reply!

I reset with "source pwr_stop.sh" and when starting with rt_ini I got:
mq_send: Resource temporarily unavailable

Is there a possibility of an error on the development station?

Hi Eiver,

mq is only used for the system message logging and you might have lost some message but it will not affect anything. I have a vague memory that increasing some quota in sysctl (fs.mqueue.msg_max?) can fix it.
