[MORELLO-SDK] Morello Linux 1.6.1

by Vincenzo Frascino

Hi All, I am glad to inform you on the availability of a new version of our SDK and base rootfs images for Morello (1.6.1). After months of hard work we are happy to share with you what we put together. Honoring our motto "Let Linux developers focus on the porting of their own application", we feel that this is another steps in the right direction. [Morello SDK] In less than 10 minutes you should be able to setup a docker container with everything you need to build an application for Morello. - Documentation: https://sdk.morello-project.org/ - Code repository: https://git.morello-project.org/morello/morello-sdk New in 1.6.1: - Dynamic linking support for llvm/musl. - Experimental C++ support for llvm/musl. - Initial version of GCC/GLibC (with static linking). If you want to try a demo of the SDK that runs on a Morello FVP (for more information on what is an FVP: www.morello-project.org) please have a look below: [Morello Linux] In less than 10 minutes you should be able to setup a docker container with everything you need to build and boot into a Morello Debian environment. - Documentation: https://linux.morello-project.org/ - Code repository: https://git.morello-project.org/morello/morello-linux Note: The documentation covers the instructions for Linux but if you know what you are doing and are familiar with docker no one stops you from running our solution on Windows or Mac. New in 1.6.1: - New kernel based on Linux 6.4. - Graphic environment support with 3D acceleration (compat mode only). - Shared folders support on FVP to simplify development. Note: This release does not include a new version of the Android environment. Further Android releases are now deprecated. Ongoing releases will focus on the Morello Linux Environment. Are we done with it? No, by any mean. This is just the beginning and we need your help and collaboration to make sure that we improve our solution to meet developers needs: your needs! So why don't you try it and let us know your thoughts? Thanks and Regards, Vincenzo

[meta-morello][PATCH] kernel: go back to nobranch fetch

by Pawel Zalewski

For some reason nobranch was removed in the past despite overall agreement that this is the way and now when the kernel has been rebased to 6.4 the fetch is failing again. Go back to `nobranch + commit ref` and stick with it. Switch to morello-last-6.1 tag while at it.
