Raspberry Pi 3 - Framework Issue

[rmc]

Hi,

I am having trouble running Legato 19.04 on a Raspberry Pi 3. The framework has been built, along with the kernel configurations, as per the instructions at: Configure Raspberry Pi - Legato Docs

When attempting to start Legato on the Pi, the following error messages occur:

root@raspberrypi:~# /./mnt/legato/start 

Message from syslogd@raspberrypi at Jun 21 16:31:20 ...

Is anybody aware of what could be the cause of this issue?

Thanks.

How to get started with Legato on Raspberry Pi3

I am a newbie. I would like to know what are the steps to get a quick startup with Legato AF running in my Raspberry Pi 3. I want to experiments some of the features that Legato is promoting such as IPC scheduling and kernel modules’ support. Can you please let me know if there is a support for RP3? and if so, can you please let me know what are the steps to follow. I have been looking at the docs and there is an option with make “make raspi”, but I could not get it to make in my host ubuntu mac…

Unfortunately, our Raspberry Pi support is not up-to-date, and one of our main issue is that Legato doesn’t work on kernels 4.14 and above. This is a compatibility issue with SMACK and we are working on addressing that, but there is no testing of Legato on RPi at the moment.

we’re cross-compiling legato for a i.mx6 board based on a SoM by Toradex and see the same issue. Our kernel version is:
Linux colibri-imx6 4.9.144-2.8.5+g5758a8e648a3 #10 SMP Thu Jun 27 14:47:17 UTC 2019 armv7l armv7l armv7l GNU/Linux

We’re willing to try/patch stuff, but any hint would be very welcome.

Could you try with latest Legato version (19.11)?
It seems that SMACK should be disabled with some kernel 4.x versions.
