Hi Alex,

We have been running Android and Linux successfully with 1.4 release and during my time with the platform I have not seen this. It looks like morello-aarch64 branches start at 1.3, so it is possible that it was never tested as in your setup. The musl-libc is not (yet) dynamic linking-capable, that is why the apps are statically linked.

Kind regards, Pawel

Hi all,

We've been working on building and booting the 1.1 Morello release on the Morello hardware we have here

ref: https://community.arm.com/support-forums/f/morello-forum/53643/building-for-...

We've got the vanilla Poky build booting on the board and now want to prove out that the CHERI support is trapping memory write overflows.

We followed Deepak's advice to build the examples from morello-aarch64, which seem to be configured to build statically.

Copying these across to the root filesystem and running results in a "Bus Error" though.

Does anybody have any thoughts on what we might be missing here?

Thanks!

Alex
