[PATCH 0/2] Add Radxa ROCK 5B+ defconfig

[Bryan Hinton]

This series adds initial support for the Radxa ROCK 5B+ (RK3588).
It introduces a new defconfig that mirrors the ROCK 5B baseline
while building from the vendored upstream DTS snapshot
(rockchip/rk3588-rock-5b-plus).

Tested on ROCK 5B+ rev 1.2 (32 GB LPDDR5) booting U-Boot from microSD card.
Build used:
  - TPL rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.19.bin
  - BL31 rk3588_bl31_v1.51.elf
  - GCC 15.1.0 toolchain

The eMMC controller enumerates even without a soldered module. SPL → U-Boot
boot verified; SD and USB enumeration work as expected.

Thanks,
Bryan

[PATCH 1/2] configs: Add rock5b_plus-rk3588_defconfig

[Bryan Hinton]

Add initial defconfig for the Radxa ROCK 5B+ (RK3588), tested on board
revision 1.2 with 32 GB LPDDR5. This mirrors the existing ROCK 5B baseline
and uses the DTS from U-Boot’s vendored Linux snapshot
(rockchip/rk3588-rock-5b-plus).

Build and test details:
  - U-Boot build: 2026.01-rc1-00232-g0673831a738b-dirty (Nov 04 2025 - 21:18:07 -0600)
  - Toolchain: aarch64-linux-gnu-gcc (GCC) 15.1.0
  - DDR TPL: rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.19.bin
  - BL31: rkbin/bin/rk35/rk3588_bl31_v1.51.elf
  - Boot medium: microSD card (U-Boot image written via dd)
  - SoC: RK3588 (8× Cortex-A76/A55)
  - DRAM: 32 GiB LPDDR5 detected
  - eMMC socket present but module not soldered (controller still detected)
  - Verified: SPL → U-Boot prompt
  - `mmc list` shows SD + eMMC controllers
  - USB EHCI/XHCI enumeration works (`usb tree`)
  - Control FDT present (`fdt addr ${fdtcontroladdr}; fdt print / model`)
  - Default environment: `fdtfile=rockchip/rk3588-rock-5b-plus.dtb`

This configuration reuses the ROCK 5B base defconfig with minimal adjustments
and builds from the upstream DTS snapshot. Follow-up patches will enable
NVMe, Ethernet, and saveenv support.

A thing we don't talk about enough is that defconfig files can use
"#include". So how much is different here from
configs/rock5b-rk3588_defconfig and could we instead do something like
configs/rpi_4_acpi_defconfig does to just augment an existing defconfig?
Next, this needs to update a MAINTAINERS file at the same time in order
for CI to pass.

Please don't include that, and make sure this is the output from a "make
savedefconfig" so that we don't have noise in the file later when it's
resynced automatically. Thanks!

Please take a look at the existing "rockchip: Add support for ROCK 5B+"
series at [1], it extends the rock5b target to also support the 5B+
variant instead of adding a new defconfig target.

Re: [PATCH 0/2] Add Radxa ROCK 5B+ defconfig

[Bryan Hinton]

Thanks, I did see that. When I pulled mainline master, I only saw the 5b defconfig and dtsi includes in arch/arm/dts. The plus dts file was in dts/upstream/src/arm64/rockchip and appeared to mirror the dts configuration in Linux mainline arch/arm64/boot/dts/rockchip for the 5b+.  I tried the dts configuration a few different ways and reduced it to just including the 5b config per Tom in the patches just sent.
I’m doing other testing on the board related to memory and timing, and hope to submit some more mainline contributions in the future.

Which TPL do you use for testing the rock5b+?

Please try the existing series and if possible review it instead of
sending a new conflicting series :-)

The plan is to use a single rock5b defconfig target for both 5B and 5B+.
And in the future the ROCK 5T should also be able to the same target.

> 
> Which TPL do you use for testing the rock5b+?

The latest ddr bin from rkbin at the time when my series was sent back
in July and August when my series was sent, should have been the
v1.19.bin blob. Did you have an issue with a TPL blob using my series?

With my series applied you should be able to build the rock5b target
and when booting on a 5B+ you should be able to see something like

  Model: Radxa ROCK 5B+
  SoC:   RK3588

and this will indicate that the 5B+ device tree is correctly used.

Jonas

I reviewed your sdram and configuration changes for the patch you sent and rebuilt u-boot with those changes applied from dts/upstream.

ok. I tested various compiles of u-boot from radx, collabora, armbian, and u-boot mainline. The different builds and device trees are not consistent for the 5b and 5b+ boards so getting everything under a single defconfig would be great.

I used the official blob referenced above and not all of the peripherals and bus power up properly. I noted that there are variations of the TPL binary in different public repositories with varying memory clock settings based on the file name descriptions, with the original file referenced above implying lp5_2400MHz.

Yes, I applied your v2 series patches and re-built.  I have a boot log from the u-boot build for your patches. I will send that as a reply to the original thread.  

As you probably know,  peripheral support on this board appears to be spread across vendor branches.
