Hi @sowvikroy,
note that you should clone legato with `repo`, cf [GitHub - legatoproject/legato-af: Legato Application Framework](https://github.com/legatoproject/legato-af#clone-from-github)
Then try to also declare the `RASPI_SYSROOT` env. variable.
It should be able to detect it by itself but it’s failing to do so.
I’ll try to solve this for the next release.
BTW, as a warning, the raspi support is quite unmaintained unfortunately.
It builds but that’s the extend of our testing at the moment.
Please let us know if you encounter any runtime issue.
Thanks

Hi @CoRfr,
I think we got a runtime issue as follows. Could you please help me with this

What is the version of your kernel? (`uname -a`) ?

Also I tried to make a quick patch that might help with the start-up.
I’ve not tried it though.

hi @sowvikroy
for more information please have a look to the following page [Configure Raspberry Pi - Legato Docs](https://docs.legato.io/latest/raspbianMain.html) which describes how Raspi is handled with Legato.
Unfortunately, we could not add more support on Raspi,
best regards
