The problem with the linker address is already solved. You can shadow the `tool/run/boot_dir/hw` path. This is explained (partly) in release notes 20.05: https://genode.org/documentation/release-notes/20.05#Board_support_outside_the_Genode_main_repository You add the empty file `tool/run/boot_dir/hw` to your repository include the original version of the genode main repository in that file with the following line: source [genode_dir]/tool/run/boot_dir/hw Now, you can overwrite certain functions, e.g., `bootstrap_link_address` to add your physical link address, or `base_src` to denote the base library package for your board. When building, you have to tweak your RUN_OPT variable in addition to the changes of the REPOSITORIES variable. Just replace the following lines in your `etc/build.conf`, which otherwise includes `[genode_dir]/tool/run/boot_dir/hw`: ifdef KERNEL RUN_OPT += --include boot_dir/$(KERNEL) endif Instead you would write: ifdef KERNEL RUN_OPT += --include [path-to-your-repository]/tool/run/boot_dir/$(KERNEL) endif I hope that help.
