Rockchip RK3576 EVB1 v10

Rockchip’s own RK3576 reference board. boot2deb ships it for one reason: its device tree is already in mainline. A build of rk3576-evb1-v10/forky therefore exercises the whole RK3576 chain, with no board device tree of ours in the picture. The kernel builds its DTB from its own tree, and u-boot builds against the DDR loader and BL31.

That makes it the SoC-path validator. When an RK3576 build breaks, building this recipe answers whether the fault is in the SoC layer (kernel definition, kconfig fragments, patch series, rkbin blobs) or in a particular board’s .dts. Compare it with the H96 MAX M9, which carries a device tree of its own.

boot2deb build rk3576-evb1-v10/forky

The board defaults to the loader u-boot series rather than the display u-boot a consumer board ships. That is the minimal rockusb image, the dev-board bring-up posture. The display and util variants are both in its supported_uboot_series, so a build can select either:

boot2deb build rk3576-evb1-v10/forky --uboot-series rk3576-util

See RK3576 u-boot images for what each series carries and The maskrom loader for streaming one into RAM.

Status

The image builds, and nobody has booted it on the hardware. It is expected in the support matrix. Every axis it resolves is shared with the H96 MAX M9, which is validated. It differs only in using an upstream DTB instead of a board one. If you have this board, a boot report is the one thing that would move it.

rk3576-generic

devices/rk3576-generic.toml is not a board. It is a tool host, and it exists so the SoC-generic u-boot images have somewhere to live. Those are rk3576-generic/loader and rk3576-generic/util, whose payload builds from the rk3576-generic control DTB and is byte-identical on any RK3576 board. Those recipes are u-boot-only deliverables (deliverable = "uboot"): they name no suite, no kernel, and no image.

Reach for them when you are bringing up an RK3576 board boot2deb has no device file for yet. They will flash and drive it before anything board-specific exists.
