In a November 4, 2025 project report, the team said Tumbleweed could start from a microSD card and reach an HDMI graphical desktop. That milestone involved Linux support as well as U-Boot: Pi 5’s RP1 chip places several key peripherals behind PCIe, adding work beyond basic SD-card boot.
What U-Boot support means on Raspberry Pi 5
U-Boot is part of the boot route openSUSE uses to reach GRUB2. According to the openSUSE project authors, the Raspberry Pi’s EEPROM firmware starts Raspberry Pi OS’s vendor-developed Linux kernel directly. openSUSE instead uses GRUB2, which relies on UEFI interfaces to locate boot files; U-Boot supplies those interfaces on this route. The project therefore needed support in both U-Boot and the Linux kernel, not just a bootloader that could start the board.
This is a different boot path from Raspberry Pi OS’s direct firmware-to-kernel approach. It matters to someone trying to boot a distribution that uses GRUB2 and expects UEFI services, rather than to every Raspberry Pi 5 owner.
Why Pi 5 required more than SD-card boot
The first step was getting the BCM2712 system-on-chip and its SD host controller working well enough to boot from microSD. But Pi 5 moves many peripheral controllers—including USB, Ethernet, SPI, I2C, and GPIO—into the RP1 chip, which connects to BCM2712 over PCIe. The SD controller remains in the main SoC, so early SD boot did not mean the other hardware was ready.

The openSUSE account describes kernel work involving BCM2712 interrupts and pin control, RP1 clocks and GPIO, the RP1 PCI device, and its Ethernet controller. A February 2025 Raspberry Pi engineer forum comment described RP1 upstreaming as dependent on BCM2712 PCIe support and discussed configuring RP1 with an overlay. That comment is a dated status note, not a complete account of current upstream support.
How support developed
May 2024: minimal boot from SD
On May 28, 2024, Andrea della Porta submitted a Linux ARM patch series adding minimal BCM2712 and SDHCI support. The stated goal was to boot a Raspberry Pi 5 from SD and get a UART console. The patch author reported testing an upstream kernel on Tumbleweed both through U-Boot → GRUB → kernel chainloading and by booting the kernel directly from the first-stage loader. This was an early boot milestone, not evidence that all Pi 5 components worked.

November 2025: Tumbleweed reaches a desktop
In their November 4, 2025 report, openSUSE authors Ivan Ivanov and Lubos Kocman said Tumbleweed booted from SD card to a graphical desktop over HDMI. They said Ethernet, Wi-Fi, Bluetooth, USB, and HDMI should work once Linux had started. At that report’s publication, however, U-Boot did not support USB, so a USB keyboard could not be used in U-Boot or GRUB2. They described U-Boot support for the BCM2712 PCIe root complex as future work for disk boot, and noted that Ethernet fixes were still in progress.
Later build guidance is not a complete support verdict
A seL4 technical reference accessed in October 2026 says U-Boot 2024.07 and 2026.07-rc5 were confirmed to function on Pi 5. It also states that, as of June 2026, U-Boot did not yet contain Pi 5 device trees; its build guidance recommends rpi_arm64_defconfig while using the device tree supplied by firmware. This is useful guidance for that documented build context, but it does not establish the complete upstream U-Boot status as of October 2026. The project’s November 2025 limitations should likewise be read as status at that publication date, not assumed to describe every later build.

What the reported setup involved
The openSUSE authors advised updating the Pi 5 EEPROM before trying their images and writing an openSUSE Tumbleweed appliance image to a microSD card. They also recommended connecting a Raspberry Pi Debug Probe while experimenting: some users had encountered a hang at the U-Boot stage, and a serial console can help investigate boot problems. This is project-authored setup advice, not a guarantee that every board or image will boot successfully.
For their installation path, the practical essentials are a compatible Tumbleweed image and microSD card. The project report does not specify a required card capacity or speed, nor does it identify a power-supply or cooling change as a requirement for U-Boot support. Raspberry Pi’s official hardware documentation recommends a 27 W USB-C supply for Pi 5 generally; that recommendation is not evidence that a new supply is needed for this bootloader work.
