The current size of the rootfs is below 98 MiB, so we can add a second root partition to the image while keeping the overall image size the same. * Add appropriate variables to the barebox defaultenv so the bootchooser can decide into which partition to boot * Use the already existing bootstate in the upstream barebox Device Tree * Map partitions in rauc-udev compatibility layer Signed-off-by: Roland Hieber --- .../barebox-vexpress-defaultenv/init/bootsource | 2 +- .../barebox-vexpress-defaultenv/nv/boot.default | 1 + .../nv/bootchooser.state_prefix | 1 + .../nv/bootchooser.system0.boot | 1 + .../nv/bootchooser.system1.boot | 1 + .../barebox-vexpress-defaultenv/nv/bootchooser.targets | 1 + configs/platform-v7a/barebox-vexpress.config | 3 ++- configs/platform-v7a/barebox-vexpress.config.diff | 2 ++ configs/platform-v7a/config/images/vexpress.config | 7 ++++++- projectroot/usr/lib/udev/rules.d/90-rauc-partitions.rules | 6 ++++++ 10 files changed, 22 insertions(+), 3 deletions(-) create mode 100644 configs/platform-v7a/barebox-vexpress-defaultenv/nv/boot.default create mode 100644 configs/platform-v7a/barebox-vexpress-defaultenv/nv/bootchooser.state_prefix create mode 100644 configs/platform-v7a/barebox-vexpress-defaultenv/nv/bootchooser.system0.boot create mode 100644 configs/platform-v7a/barebox-vexpress-defaultenv/nv/bootchooser.system1.boot create mode 100644 configs/platform-v7a/barebox-vexpress-defaultenv/nv/bootchooser.targets diff --git a/configs/platform-v7a/barebox-vexpress-defaultenv/init/bootsource b/configs/platform-v7a/barebox-vexpress-defaultenv/init/bootsource index b42659c5e78b..4432e021fb0f 100644 --- a/configs/platform-v7a/barebox-vexpress-defaultenv/init/bootsource +++ b/configs/platform-v7a/barebox-vexpress-defaultenv/init/bootsource @@ -4,4 +4,4 @@ if [ -n "$nv.boot.default" ];
