- Walk the partition table if the requested partition is not bootable Previously, if the specified boot partition was not bootable the bootloader would stop and advance to the next BOOT_ORDER. If the new PARTITION_WALK option is set to 1 the bootloader will now check each partition in turn starting from the specified partition before advancing the BOOT_ORDER. This feature is intended for use with A/B systems to handle the case where autoboot.txt is missing / corrupted. This change enables the system to failover to the next available bootable partition. The autoboot.txt file is not scanned during the partition-walk phase i.e. there is no recursive processing of autoboot.txt files. This option is only supported on physical block devices (SD, NVMe, USB) and not RAMDISK. USB assumes a single high speed device, partition walks on multiple USB devices is not recommended and may cause timeouts.
- Improve keyboard handling in boot menu Try and make it more likely that we have enough time to perform key detection. Ignore mice, which were being enumerated and slowing things down.
- Add DT /chosen property signed-boot boot.img hash Make the sha256 hash of the boot.img file available via device-tree /proc/device-tree/chosen/bootloader/boot_img_sha256 if signed boot is enabled.
- filesystem: GPT autoboot/reboot partition number fixes for Pi4 and older
- Fix problems when setting arm_freq_min=arm_freq and display clocks if performance governor is not enabled.
- Add set_reboot_order API and config.txt properties If set_reboot_order is defined in config.txt or set via vcmailbox then this will override the bootloader config BOOT_ORDER property on the next reboot. The parameter is stored in a reset safe register and is cleared by the bootloader after reading it. Typically, the config.txt value only be used via rpiboot to override the boot-order on the next reboot. Otherwise, it should reside in a conditional section so that the boot order is not overridden on every reboot. Example, test network boot sudo vcmailbox 0x0003808b 4 4 0xf4612; sudo reboot
- Improved SDRAM refresh timings for Pi5 - 16GB
- Add an option to wait for the power button to be pressed before booting. If POWER_OFF_ON_HALT=1 and WAIT_FOR_POWER_BUTTON=1 in the bootloader config then the bootloader will wait for either the power button to be pressed or an RTC alarm before booting. The wait state switches the PMIC to STANDBY mode which is the lowest possible power state.
- Update SDRAM timings for BCM2712D0 products.
- Fix a potential timing issue introduced in the 2025-01-06 release when enabling PCIE_PWR when booting from SD/USB.
- Stop the fan after after fan-probe After the fan-probe has completed drive the fan PWM GPIO to high if a fan was detected and let the OS take over.
- Add SD_QUIRKS for hardware bringup / workarounds Add a new SD_QUIRKS flags property which can be used to disable high-speed mode (bit 0). Other bits are reserved for future use.
- Change uart_2ndstage default to 1 on Pi5 Change the default to 1 because this gives useful diagnostics for device-tree loading with minimal overhead. Set uart_2ndstage=0 or BOOT_UART=0 to disable this.
- Move M.2 HAT+ detection to early boot. Initialse M.2 HAT+ detection before DDR init to give NVMe drive firmware more time to boot.
- Disable fan PWM before shutdown Drive the RP1 fan PWM GPIO high before entering the VPU sleep (POWER_OFF_ON_HALT=0) to stop the fan spinning.
- Disable fan PWM GPIO between RP1 init and fan probe Drive fan PWM GPIO high during early boot to disable the fan until it is probed during the device-tree setup stage. This stops the spinning at max rpm during network-install.
- arm_dt: enable_uart defaults to 0 on 2712 The default value of enable_uart on 2712 is 0, regardless of the presence of the debug UART cable, so guarantee that the default is always set correctly.
- Add net install to boot menu Press N (or shift).
- enable_uart: Require enable_uart=1 to enable RP1 UART console See: #643
- Enable banklow (and so NUMA) by default banklow=1 (2712) and banklow=3 (2711) give the best performance.
- enable_uart=1 now enables a Linix UART console on the 40-pin header unless a cable is detected on the dedicated boot-uart.
- Recreate internal bl31 stub from clean git tree to fix dirty commit message.
- rp1fw: Add FIFO_STATE & DRAIN_TX, fix CAN_ADD_PROGRAM RP1 firmware eb39cfd516f8c90628aa9d91f52370aade5d0a55 adds methods to drain the TX FIFO and retrieve the state of both FIFOs. It also fixes the CAN_ADD_PROGRAM implementation, which was fatally broken.

- Enable initial_turbo=60 by default This reduces the time to get load and decompress the kernel.

- rp1-fw: Add the mailbox firmware interface, and PIO support that uses it.
- rp1-fw: Turn off unused 25MHz Ethernet refclk
- Update recovery.bin to the most recent version required for CM5 and Pi500. (firmware version 2024-10-21)
- NUMA - Add system_heap.max_order=0 when needed - configure this setting automatically depending on whether NUMA is enabled.
- Fix PCIe BAR setup issue which prevented NVMe boot from working with some PCIe switches See: raspberrypi/firmware#1833
- Boot-menu improvements Remain in the forced boot mode until the menu is used to select a different boot-mode or reset to the original boot-order.
- Introduce a new boot-menu feature where pressing SPACE at power on gives the user a one-shot option to select a different boot mode. e.g. Select USB boot if the default SD card is corrupted or unavailable.
- Display the bootloader network-install UI for longer on a cold boot to make this feature more visible to first time users. To revert to the previous behaviour remove NET_INSTALL_AT_POWER_ON=1 from the bootloader config.
- Support non-UUID HAT mapping Extend the HAT map support to allow matching on product and vendor strings, as well as product ID and version. As a minimum, there must be a product string - if that matches, the other keys are considered. Without a product key, the UUID is compared as before.
- Remove requirement for GPT ptable array to be at LBA-2 See: #585
- 2712C1 clock manager improvements to slightly reduce idle power ~50mW saving

- debug: Only display the program_pubkey log if configuring secure-boot
- Default to 2GB start for PCI bus addresses on 2711 and 2712 This change also constrains the window size to 2GB, so all PCI bus address assignments fall below 4GB, avoiding a potential bug with 32-bit BARs in esoteric bus topologies (e.g. lots of GPUs).
