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](https://docs.legato.io/latest/raspbianMain.html) When attempting to start Legato on the Pi, the following error messages occur: ```bash root@raspberrypi:~# /./mnt/legato/start Message from syslogd@raspberrypi at Jun 21 16:31:20 ... Legato: *EMR* | configTree[945]/framework T=main | messagingInterface.c DirectorySocketReadable() 559 | Failed to receive client fd from Service Directory (-6: LE_FAULT).

Thanks. ---

Hi @rmc, I suggest you search into the forum similar topic about RPI 3, as there several of them which could help you .

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.
